Laptop battery health isn't 100% anymore

Hey everyone.
I just checked my laptops battery health, and it's now 73 percent, and not 100% anymore. I don't know what to do to boost it up to 100% anymore
Please help me. I don't want to spend money on a new laptop battery. Do I have to???

You can't. The battery's maximum charge level will decline with use. Since you've provided no other relevant information about the battery it's impossible to provide any more assistance.

Laptop battery always on full, 100% when connected to AC

Hi,
I usually use my laptop on AC with battery removed. Last week I used it from battery, then connected the laptop to AC. If I remember correctly battery started to discharge to 90 something percent after a while, but now it is always on full.
acpi -b
Battery 0: Full, 100%
I have the following packages installed:
local/laptop-mode-tools 1.61-2
local/acpi 1.6-1
local/acpid 2.0.16-3
local/linux 3.5.3-1
My question: is it fine to have the battery always on full? Or was it better when it was charging/discharging automatically?
Thanks

Let me clarify myself. When the battery is in place and the laptop is running from AC, sooner or later you will see that the battery is fully charged. When this fully charged status has been accomplished, charging stops and battery starts discharging (let's say from 100% to 95%) then charging starts again. I think that was the way it worked some weeks ago. My experience in this very moment is that battery is reported to be fully charged. Always. No drop from 100%.
I think the charger electronic prevent the battery from overcharge, but I don't know why is the change in the behavior described above. Was it a bug and now it's fixed or now we have a bug.
Anyway, people contradict each other how to prolong the health of a battery, but I found that usually they say if one usually uses a laptop from AC the best thing is to remove the battery when charged to 50-60% and store in a dry place, and from time to time it's advised to charge/discharge it.
Uh... what make is your laptop, for example I'm using a Compaq laptop so my laptop has a big Compaq at the base of the screen and nice big Q on the back. I wouldn't be surprised if your laptop is a Dell. Google for product reviews for your laptop: So, since my laptop is a Compaq and it's a CQ60-420US
I'd type
CQ60-420us battery charge/discharge behavior
or something like that into the address bar for chromium, and then press enter.
EDIT: The best way to use/store a battery, and you can quote me on this 'cause I took a Electrical engineering class last semester and know what I'm talking about, is to just charge it all the way up and then use it till it's almost out of battery power. If you charge it when it's at half capacity it will eventually do bad stuff to the battery, or something like that. Anyway, it's just healthier for the battery to have the chance to fully discharge per every full recharge. You don't have to let it go all the way to 0%, 'cause your laptop will probably cut off if you do that, so let it get as close to zero as you feel comfortable with.
A good program for keeping an eye on power stuff is wmacpi. It's what I use, since conky isn't reliable on my hardware when it comes to the battery. Install it thusly:
packer -S wmacpi
and run it thusly:
$ wmacpi
If you use openbox, like I do, you can add the following line to your ~/.config/openbox/autostart file.
wmacpi &
Here's an image of wmacpi showing a laptop being run off AC power.

My brand new laptop battery doesnt charge upto 100%

my battery does not charge upto 100% its stops at 99% after hours of charging. what do i do?

Hi @ekezie
Welcome to the HP support Forums!
I understand that your notebook battery will not charge to 100%, I am happy to assist.
Since it is new did you interrupt the charge cycle at all. On many notebooks there are for lack of a better word charge thresholds to prevent the battery from charging when it is already above a certain level when first plugged in. This is to prevent repeated short charge cycles, which can reduce battery life. That may be the sort of thing that is happening.
However I would recommend taking a look at this page, and running the tests.
Testing and Calibrating the Battery (Windows 8)
Here is a document you may wish to look at, for future reference as it is useful for prolonging the charge duration.

IStat Pro Battery Health 100% No Way!?

iStat Pro seems to be functioning correclty I have removed and reset it, but I continues to display 100% Battery Health. It also says I am 123 Cycles in, and I have had this laptop for some time now.
1. More then likely this is not the correct information, but how do I get this widget to display the correct info?

islayer.com states...
"What is battery health?
This is a comparison between your current battery capacity and the capacity of it when it was new. For example, if your battery lasted 5 hours when it was new, a figure of 50% suggests you should get 2.5 hours out of your battery now.
As you can see, battery health isn’t something you have control over and there’s not much you can do to change the figure without buying a new battery. Don’t worry about it though, it just means that your battery doesn’t last as long as it used to."
My System Profiler States...
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 5356
Remaining Capacity (mAh): 5356
Amperage (mA): 133
Voltage (mV): 12590
Cycle Count: 126
iStat Pro displays 100% Battery Health. How is this possible with almost a year of solid use and 126 cycles.

Best Battery Health not working in Windows 7 after Windows 8 installation

Hello everybody, I'm having an annoying problem with my G475.
It came with Windows 7 installed, and the option "Best Battery Health" was working fine.
Then I upgraded to Windows 8 (fresh install) and installed the Energy Management drivers.
Since "Best Battery Health" wasn't working on Windows 8, I installed back Windows 7 (fresh install).
But now, the option "Best Battery Health" is not working anymore!
It stays checked in the software, but the battery keeps charging until 100 percent.
I did the "Battery Gauge Reset". It finished and the problem persisted.
I also tried to change settings in safe mode, didn't work.
Please help!

hi kauptman,
Welcome to the Lenovo Community.
Just want to verify, have you also installed the following in order:
1. Intel Chipset Driver
2. AMD Matrix Storage Manager Driver v1.2.1.210
2. Lenovo Energy Management v6.0.1.5
If the apps listed above are already installed, I recommend you:
1. Drain the battery (use the computer until it prompts you that the battery is low)
2. Change your power plan settings to Power Saver / High Performance and re-test if battery stops charging at 90% or 95%.
If the problem still persist, I recommend you restore the unit by using the Lenovo Recovery Disc. If the recovery partition is still intact, click here on how to create a facotory restore dics.
Hope this helps.

SCCM Report for Laptop Battery Condition

Good morning,
We are in a situation where we're needing to monitor conditions of laptop batteries in the school district I manage. I have added the laptop batteries class(Win32_Battery) and have all required/requested information checked under this class. This
has been set for a week, so all devices should be inventoried by now.
How do you recommend my getting a report together that shows battery condition/etc? The fields I would like to see are ones such as:
Win32_Battery
battery status
design capacity
design voltage
Expected Life
Error Description
Full Charge Capacity
Really anything that will help us in knowing which laptops batteries need replacing.
I am not that knowledgeable about SQL reporting/SCCM reporting, so any help in getting this is greatly appreciated. Any resources that you can point me in for getting more familiar with creating my own reports would be greatly appreciated. I
don't even know where to begin.
Thank you!

Good you have added the class. Please use the following link for the detailed information about Win32_Battery:
https://msdn.microsoft.com/en-us/library/aa394074(v=vs.85).aspx
Last Full Charge should guide your decision on replacement.

My laptop had water spilled on it 3 days ago, I let it sit as instructed by best buy . I am on it right now but the mouse movement isn't smooth anymore and it is slower. The first time I turned it on it didn't respond at all, how bad is the damage.?

My laptop had water spilled on it 3 days ago, I let it sit as instructed by best buy . I am on it right now but the mouse movement isn't smooth anymore and it is slower. The first time I turned it on it didn't respond at all,can anyone tell how bad the damage really is without actually seeing it ? Do you think maybe it will be just a simple repair or am I looking at a whole new logic board?

Until you take it in so that a technician can look at it, it is all guessing and nothing more.

Having serious issues with battery health, how could it be?

hello,
newbie to this forum but not to apple devices.
my big brother gave me his MacBook Air about 2 months ago. he bought it in august of 2009. when i got it, it ran Windows 7 (dont ask me why that what he wanted). i did update to the system and installed snow leopard etc...
after install the iStat pro i noticed that the battery is in good condition, 93%. i thought he ruined the battery cause he always plugs his laptops/netbooks to a power source.
i dont understand why but in the first month i had 90%-92% health, and in the past few weeks it went down to 88%-90% and a few days ago it was 86%. today i went to school and when i opened my mac the battery health os on 84%!
i really dont understand why.
i follow the instructions and wait until the battery is empty, recharge to 100% and again waiting... etc... there is no overuse and when im home i usually work on my stationary computer.
the computer overall is in great shape, i dont understand the problem maybe one of you guys can help a brother out...
thanks in advance!!!

hello,
newbie also to this forum, does anyone can confirm that when the battery gets older, the maximum load percentage will decrease so that 100% capacity will never be reached anymore?
Tks.
Erick

Any way to prevent charging my laptop battery??

Hi all,I own Pavilion 6080se,I would leave my battery in my laptop,but I'm worry about it,coz I think I short my battery life with this,I think coz of draining 1 persent my adaptor charge it to 100% and with discahrge 1 persent again this proccess Continuing....So it ca make my battery damaged....
am I wrong??any sugg.? is there any apps to control battery charging??I mean any options to disable charging....
I use Windows 7 64-bit....
regards...

There aren't any programs to control battery charging for your laptop so it will always charge to 100%. Some business laptops (Lenovo and Dell) support battery thresholds and disabling charging.
the battery can become damaged over time if the computer constantly charges the battery from 99% to 100%. if you don't use your battery very often, you can drain it to 40-60% and remove it from your computer.
The battery can be worn down from not being used also. If you never use a laptop on battery, it may simply go bad one day. I have several batteries with very low cycles, and they don't work anymore. I also have a battery with nearly 800 cycles and it works perfectly.
HaggisCat: I don't understand where you're getting "you get an hour" from. Most laptops last around 2-6 hours with a battery that has little to no wear. Additionally, 13% is probably what you have your specific computer set to. The default tends to be around 4 or 5% when the computer hibernates or shuts down.

Battery Health Degredation

I've had this MacBook for about two weeks. In only three cycles the battery health is down to 95%. Is this normal or is this a bit soon for it to have lost 5%?

No, it isn't normal. I had bought a new battery and in two weeks I was shocked to see it went down to 77%! I went to an Apple store to have it checked out, and they replaced my battery free of charge. Sometimes new batteries go faulty, so I would advise you to do the same. You paid enough for the computer already; you don't need to pay $100+ dollars for a new battery.

Battery health decreased rapidly after charging problems.

Hy a few weeks ago the health of my mid 2010 MacBook Pro was still 79% which is normal since it has more than 1000 cycles.
Then following incident happened:
My battery was almost discharged, 30% or so, so I connected it to the AC power. After a while I wanted to see how much it was charged but the indicator in the corner still indicated the same 30% or so, only when I disconnected it it changed to something in the 80% range. I used my computer for a while like that and I noticed that the battery indicator was not chaning. Only when I connected or disconnected the AC power did it update.
I decided to reboot the machine and this solved the problem. I recently noticed however that my battery health now dropped to 63% which seems very much in a short period of time.
I know that normally charger will deliver less current to the battery when it is near 80% in order to prevent overcharging and maintain battery life as much as possible. I wonder however if the drastic decrease could be because of the power management thinking that the battery was only partly charged and thus delivering to much current to an almost full battery? If this is the case do you think that Apple would intervene for the costs of a new battery? I know I would have had to replace it sooner rather than later but this does change a lot I think. My computer is not in warranty anymore and I don't want to pay 49€ for one intervention. There are also no official Apple stores in Belgium and the authorised resellers really don't offer the same service.

sweex,
since your battery has over 1000 cycles and has 79% of its original full charge capacity remaining, Apple considers your battery “consumed”; they will not intervene for the cost of a new battery. It’s entirely your decision when to replace your battery, but irregular charging results are to be expected for as long as you use your present battery.
If no Apple-authorized service center in Belgium offers the option of changing the battery, then you should let Apple know so that they can find an organization who will do so. I don’t know where you are in Belgium, but this search around Brussels shows seven different Apple-authorized service centers which all claim to service Macs, and the one in Aalst is noted as being a Premium service center.

Battery Health and ways to bring it up again?

I've had my MacbookPro for a little over two months now and 31 cycles on it. However, I have already lost 7% battery health, leaving me at only 93%. I'm pretty sure that this is not good, and that the loss shouldn't be this rapid.
I'm sure it has something to do with the way I use the computer. I leave it on quite often, which I know isn't a good thing, but had no idea that it would drain the battery like this. In some cases the computer is on for days at a time. I've gotten into a routine where each morning I turn it off for the bus ride to school, where I use it throughout the day. The night before it remains on so that I can quickly check things in the morning.
I currently use my MacbookPro as a semi-desktop. I have it hooked up to an external monitor, and use a wireless mighty mouse and wired keyboard, which is primarily the reason it's on for such long stretches.
Now that you have some background as to what I do with the computer I'd like to know if there is any way to replenish the battery health, or if that 7% is lost for good.
I've read up on this calibrating of the battery business, and I'm going to try it this weekend (can't during the week because I need it fully charged for school each day).
What exactly does this do? Does it actually replenish the battery health or just determine it's actual current percentage?
I'm using the widget iStat Pro as my monitor of battery health.
If any other information is required, I'd be happy to provide it.
Thank you.

dnovelta:
use the battery frequently and lightly for best longevity. Apple states "An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge."

Courcoul:
Full Charge Capacity (which is what the specific battery clocked at the factory when first tested).
Just a minor correction, but can be significant. Full charge capacity is not "what the specific battery clocked at the factory", it's a nominal value, i.e. a general property of the battery type, not that specific battery. Specific batteries have a range of full charge capacities (when new). In fact, it's not even measured, it's calculated - for the 15", it's a 60 Watt-hour battery (from the specs), and it runs at 10.8 V (printed right on the battery). Thus, with a basic formula (W = V x A), an algebraic rearrangement, and some simple math, 60 Wh / 10.8 V = 5.555 Ah = 5555 mAh (~5500 mAh, which iStat uses as the denominator for "health", although I have read that under Leopard iStat uses 5600 mAh, just a rounding difference). My 17" with a 68 Wh battery calculates to 6296 mAh, ~6300 mAh - my replacement battery actually started with ~6800 mAh in System Profiler.
Just FYI...

MacBook Pro 13'' late 2011 battery health problem!!! HELP!!!

I have a MacBook Pro 13'' late 2011.
It's this normal? How do I increase my battery health?
Can I change my battery?

When did you buy it?
Do you run it down to near zero % before recharging? Which is a bad thing to do.
Do you charge it to 100% before you take it off the charger?
Do you always disconnect the charger once it reaches 100% even if you are right next to an AC outlet. Which is a bad idea.
Batteries only last so long. Over use it and it will go bad sooner.

MacBook Pro battery health?

I have and early 2011 13" MacBook Pro. The other day, the "service battery" warning came up, so I took it to the Apple Store. The "Genius" there told me that because I do not let my battery die every time I use my laptop, I am mistreating the battery and therefore the battery cannot be replaced on Apple Care. At the time, I had about 295 charge cycles on my almost 2 year old laptop. When I told the tech I didn't know this because I was never told I had to let it die every time I used it, and that they should inform you of that, he snarkily responded "well, when you buy a car they don't teach you how to drive it".
The man told me to let my computer completely die, and then let my laptop completely charge without using it for several days to "retrain" it, and that AppleCare can only replace a battery that's "in the red". When I got home from the Apple Store, the warning light was gone despite me not touching my laptop at all.
I did some research and the Apple website, first of all, said it would replace a defective battery if it shows diminished capacity or it's failed, not just failed. I also noted that these batteries are rated for 1000 charge cycles. Also, I saw that the Apple website recommended fully discharging your battery once a month for optimal capacity, not after every use. This is what I already do.
At the AppleStore, when the tech was running his software I noted that my battery health was about 80.5%. I installed a battery monitoring application from the App Store called Battery Guard and it is telling me I currently have battery health of 78% and 300 charge cycles, so it seems to me that by allowing my computer to discharge/recharge, my battery health is declining.
Does anyone have experience with this, or advice about what I should do? I'm considering going back to the Apple Store and confronting them with my new knowledge that I got straight from the apple website.

That's the worst advice someone can give you. You don't have to let your computer run out of battery or you will damage more the battery. Instead, I recommend to make full cycles (discharge the battery, put it to charge when you consider necessary and charge it fully).
Unibody Macs batteries are designed to have 80% of their capacity after 1000 charges. Read > http://www.apple.com/batteries/notebooks.html Something happens with your battery, so take the computer to an Apple Store or reseller to have the battery replaced, more when OS X is telling you that your battery has to be replaced

Can Apple replace my macbook pro (mid 2012) retina's battery if I think that the battery health has gone bad/in need of and renewal?

Can Apple replace my macbook pro (mid 2012) retina's battery if I think that the battery health has gone bad/in need of and renewal???
I've had my Macbook for about 11 months now and i use it every day; its gone though about 420 cycles of charging and using the power, and i noticed the battrey preformance has decreased (as expected). The problem isn't sevear yet but it would comfort me knowing that i could replace the battery in the near future
Please contact me or answer the question if you know anything about this!

No only if they think under warranty/AppleCare, but your likely able to pay for a new battery if they have them, which they might not yet since it's such a new machine still.
BTW, I have a Early 2011 17" MBP, 27 months old, charges to 97% and has only 14 cycles.

Laptop battery health isn't 100% anymore
