Ibook battery or powerbook battery?

I am still struggling(ibook or powerbook)and was wondering how the 12 inch powerbooks battery holds up in real world conditions. How many hours of dvd can you watch? Are there settings you can change or different batteries to buy?

Well personaly I would go with the PowerBook they're much faster and the 12 inch is really portable. I have a 12 inch PowerBook and when I have the screen brightness to the lowest setting before the back light goes off and the volume off along with the bluetooth I get about 5:15 min. which is fine for me when I'm on a road trip with my laptop I turn bluetooth and airpot off and turn the screen a little bit up and the volume up I get just a little bit less then 5 hours. There are settings you can set that can make it longer too. Thanks hope this has helped

12" Powerbook BATTERY PERFORMANCE NO GOOD

I have owned a 12" powerbook for just under two years.
The battery only lasts 4 - 10 minutes.
Apple support says that my only solution is to purchase a new battery. I am a bit disappointed

I was getting only 1-2 hours the first year and 1 hour the second....I tried a lot of things to fix this--everything everyone else mentioned and more.
SHARP CONSTRAST: My 12 ibook G3 (4 year old) still has a great battery and runs for 3-4 hours typical (airport on).
I see a major design flaw. The processor should be further from the battery and the battery should be closer to the fan. The machine runs too HOT for the lithium battery they ship.
I suggest that everyone reads http://www.batteryuniversity.com/ See if you are taking care of your battery. I was able to get a free replacement. I noted that degradation started day one as a result of excessive heat (talk to customer service higher ups).
Li-ion batteries are not all created equal-batteries Apple shipps now are said to be more resistant to heat degradation--we will see!
My battery (model A1060) was not on the list for replacement, but I think it should be included. It would be nice if people note their battery model number in this forum.

Dead ibook.... new battery...battery on moherboard???

I have an iBook 500 Mhz... it recently started having issues with the date and time wich i attributed to the dying battery that didn't hold the charge for long... one sad day it didn't turn on anymore.... which i attributed once again to the dead and discharged battery... so i bought a brand new battery from the apple store wich came in with half charge... so i plugged it a few hours ago to completely charge the battery before turning on the computer (as it said on the manual when the compter was brand new). So now i looked at the battery charge status and the same two leds are illuminated... seems like it is not charging.... and i tried to turn the computer on to no avail...
any comments or suggestions...?
does the ibook motherboard has a battery like the desktop computers? when that battery (which among other things holds the date and time) dies the computers don't turn on... could that be the case here?
Thanks for your help...

Hi, and welcome to Apple Discussions.
Does the adapter charge the battery? Does the adapter power the iBook?
Have you tried resetting the PMU?
In our experience here, if there is a problem with the dc-in board, the iBook will not run on the AC adapter, nor will the adapter charge the battery. The iBook will only run from a charged battery. If the battery charges and/or the iBook runs on the adapter, then it is likely not the dc-in board.
The same symptoms can happen with a bad adapter (no charging, not running on the adapter).
This doesn't sound like what is happening with yours, however.
There is a capacitor on the logic board which maintains the date and time settings. That capacitor could be malfunctioning, or it could be a malfunctioning PMU (also a part of the logic board).

PowerBook battery calibration - reserve battery power - Dr. Battery

Hello,
I have a new replacement battery from Dr. Battery for my 12" PowerBook G4.
I decided to calibrate the battery as described by Apple. That is, from a full charge, keep working on battery power and keep doing so when it gets to near zero when you see the 'plug in to power or computer will go to sleep' message. The reserve battery power will kick in and the computer will sleep after a few minutes; you'll see the twinkling light on the latch come on. Shortly after that, charge the battery to full.
This is how my original Apple batteries used to work, always. But the Dr. Battery battery simply crashed or shut down my PowerBook soon after the 'plug in to power or computer will go to sleep' -- the laptop couldn't/didn't go to sleep. What's more, when I restarted it, the date had reset to 1-1-1971. Does this mean that a Dr. Battery battery cannot store reserve battery power? Is there some way to fix it?
The strange thing is that the first time I calibrated in this way with this new battery in the first week of January, it *did* work like it should.
Thanks for any info.

The reason the time and other Prameter RAM settings were altered is because the G4 "12" Powerbook does not have a separate PRAM battery to maintain these values. Instead it uses a small capacitor which will maintain the PRAM settings only for a short time such as when changing a battery. The battery evidently spent it's charge when your PowerBook shut down.
I use a neat utility named coconutBattery to monitor battery status.

Is iBook G4 (early 2004) battery hot-swappable during sleep

Is the battery of an iBook G4 (early 2004) hot-swappable while the computer is in sleep mode and the power adapter is not connected?

No. Download the iBook Manual from this page:
http://www.apple.com/support/ibook/
On page 46 of the manual, it says to shut down the iBook before removing the battery.
The online instructions for iBook battery replacement can be found here:
http://docs.info.apple.com/article.html?artnum=88121
Again, it tells you to shut down the iBook before removing the battery. This has not changed for the iBook G4.
Here is the list for part numbers for backup batteries:
http://docs.info.apple.com/article.html?artnum=86181
Note that all iBooks are listed as n/a (not applicable) when it comes to backup batteries. Since your iBook does not have a backup battery, the battery is not hot-swappable.

Best battery for Powerbook Titanium?

Hi,
I just bought a Powerbook Titanium 1 Ghz from a friend and want to replace the battery. The battery gives me about 1 hour of life and runs dry even when it is off. I've seen 3rd party batteries for about $90. Can anyone point me in the right direction on my first step to improving this classic?
Thanks.

Does anyone know anything about these batteries? I see them sold from various resellers and on ebay, I think they are far east manufactured and are much cheaper than the newtech batteries.........
The question is, are they any good?
http://www.global-stores.co.uk/model.php/181771+a1078laptop-batteries?gclid=CIOYhvvQpZACFQ6ZQwod6FHhhQ#UNMAK012
I have two batteries which are down to about a quarter capacity and don't really want to spend another £100 before Christmas on a new battery.
Cheers

Is my original powerbook battery ok?

Sorry, if this subject has been covered in previous threads. I've trawled the web with no joy, so far.
My original powerbook battery which has hardly been used and shows fully charged (on laptop screen indicator and battery led lights, when battery check button is pressed) will not run the powerbook. Without the power adaptor being connected, the powerbook shuts down after minutes.
Can anyone suggest a fix on this, or point me in the right direction for further information.
Thanks, in advance

Your battery is dead, partly because it has hardly been used and partly because it's old. The average lifespan of a Powerbook battery that has been treated well is 2-4 years. A few batteries last longer than four years, but they are rare. A battery that sees little or no activity will die faster than one that is used lightly but regularly.
You'll need to replace your battery. When you get a new one, read this outstanding User Tip for information about how to make it last:

IBook sometimes boots on battery power

I recently inherited an 800MHz iBook G3 that has been acting strangely. Its internal hard drive was shot (it made loud clicking noises) but I got it to boot off an external firewire HD. The machine works great when plugged in to AC power, but acts very strangely when on battery power. It wouldn't boot on battery power, but if the iBook was running I could unplug the adapter and sometimes the iBook would run for a while and then shut off and other times it would immediately shut off (the battery was 100% charged).
I replaced the internal HD, hoping somehow it would solve my problem, but it didn't. I have done some more experimenting and it seems if I have had the iBook plugged in to AC power for a while (like overnight), the ibook will boot on battery power and run anywhere from 10 seconds to a minute before powering completely down. After that, the machine is completely dead and I have to plug it in to AC power to get it to boot again. Also, when it reboots, the time is messed up. I get an error message that says "Your computer's clock is set to a date before March 24th 2001. This may cause some applications to behave erratically. Please use the ..."
I have reset the PRAM and PMU repeatedly, I have tried other batteries (and while none of them were new they worked in other ibooks) with the same result. I also tried my battery in another ibook and it booted and ran that ibook just fine. Something in my ibook just shuts it down. I get some sort of system halt call in the log file.
I'm at a loss... anybody have any ideas as to what could be wrong or what I can do to fix it? Thanks for the help.

Hey JW.
Well like SU says:
"It sounds like there is a bad connection between the battery and the computer. "
So what I have seen on these is a bent locking tab on the battery lock. I had a few in here like that. I could lift the iBook 1" when it was running on battery and if I dropped that small bit it would shut down. Bending the locking tab back solved the problem. Careful it's fragile.
Also like Rhonda says it could be a logic board problem.
I've seen the super capacitors on the G3s go bad. Typically it's a .22 Farads @ 5.5 VDC. What happens is that the cap blows up (probably due to over filling like in the classic cases of cap failure in the past). It's easy to see since the outer case gets peeled back.
If you're date and time is constantly messed up I'd suspect that. I've replaced those caps with ones I bought from Electronics Goldmine.
Since that cap holds settings on the PMU it would also affect power if there were small transients that could cause you problems. The super cap system is designed to hold settings for around 30 seconds while you change batteries but if that cap is dead it wouldn't hold settings for a millisecond.

"battery not available", battery not charging

I just bought a NuPower battery fo my IBook G4. It's been working fine for a month or so. However, now my computer won't charge the battery. Near the battery icon at the top of the screen, it at first says "caluculating..." and then says "battery not available". Further, sometimes even when the power cord is plugged in (and the LED's are lit up), it still runs on the battery power and says the power is not plugged in. And, the lighting on the LED's do not correspond at all with the battery charge(i.e. it is sometimes green even though there is no battery power). Maybe these are 2 different problems?
Any advice would be appreciated-I'm no where near a MAC service provider.

Old battery and inaccurate battery guage

My 3 year old Powerbook battery seems to be on its last legs.. I am only getting a little over an hours usage before it poops out. What bugs me though is that the battery gauge in the menu bar doesn't reflect this.. it tells me I am at something like 80% when my PB puts itself to sleep due to the battery being drained. I have 'calibrated' the battery, but that doesn't have any effect.
Is this just the way it works? I would have expected that the battery gauge would go down quicker, in sync with the battery, but it seems the gauge is out of sync with the charge left in the battery.
A second question - my battery info shows the full capacity and the remaining capacity to be pretty close - how come I am running out of juice?
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 7540
Remaining Capacity (mAh): 7536
Amperage (mA): 0
Voltage (mV): 12296
Cycle Count: 408
Thanks for any advice for a battery know nothing..

What you're seeing is a lithium battery about to die. It's not unusual for the battery to work for awhile and then just suddenly lose power - so your battery gauge may be working correctly, it just can't predict when the battery will suddenly drop off
Apple says a properly maintained battery should retain 80% of it's capacity after 300 charge/discharge cycles. If you haven't read it already, Apple's article on battery maintenance is at http://www.apple.com/batteries/notebooks.html

Battery Recall / New Battery is horrible!!!

I signed up for the battery recall for the MacBook Pro 15" and received the replacement battery the next day. The old battery would give me a charge for about 2.5 - 3 hours. On a full charge the new battery only gives me about 1:17 average. What can I do about this?
The only difference is that I upped the RAM from 1 GB to 2 GB.

Interesting to read so many mentions of problems with battery serial numbers.
According to Apple my fairly new MBP is entitled to a new battery as the Bat serial number ends with 75B.
When I fill in the on-line form I am told that my battery serial number is either in error or does not need replacement.
Does this mean that some batteries ending in 75B (and the others mentioned by Apple) do not need replacing.
My MPB has a battery life of only about 2 hours - which is about the same as my Xp laptop I have cursed for so long.
My former ivory iBook had a useful battery life of over 5 hours so what we now gain in speed and hype we lose in lap time.
Anyone else had similar probs?

My battery recall replacement battery just died :(

My nearly-three-years-old iBook G4 had a battery that was part of the infamous bad batch that had to be recalled so dutifully I entered my details to the recall page got my replacement battery and sent off the might-potentially-explode-at-any-time unit in the UPS box to be disposed of by Apple. This was a year ago or so I can't really remember.
Yesterday I unplugged my iBook and took it downstairs to copy some files over to my external hard drive, plugged in the firewire cable, started copying and then - foomp - my iBook just switches off. Odd thing to happen I thought - not so odd more oh-god-no! was that it wouldn't switch back on.
After pressing and holding the power button and removing and replacing the battery a few times I get a bit scared. My white plastic wonder is dead! I take out the battery one more time and press the button to give a charge status and it gives no lights! Not even the one green blink for 'please charge me now I'm thirsty!'.
I get the power adaptor and plug it in to the wall and the other end into my iBook (no battery inserted yet) - green ring lights up - press the power button and I get the reassuring chime! Yay! iBook lives again!
When I finally get booted into OS X I plop the battery back in the power plug light turns orange and the menu bar shows 'Charging..." and the battery shows 0%?
Zero percent? How come? My iBook stays plugged in the vast amount of time fully charged up and ready to go, every now and then going cable free to be my internet browser while I watch TV in the living room.
But after some time the menu bar still show 'Charging..." and "0%"?
I leave my iBook there for some time more, the power plug still glowing orange, before I check the underside and the battery is cold (far colder than the rest of the now mildly warm iBook), so definitely not about to explode. Good news.
I try all the usual tricks like resetting the PMU and PRAM and NVRAM and permissions etc. etc. but still "Charging..." and "0%".
My other battery (a spare I bought a few months after my iBook) works fines and charges lovely so my iBook isn't to blame.
Here's what I need to know - is this battery a goner? Can I send it to Apple to be repaired in some way (I doubt I'll be able to get a warrantee replacement out of this I'm fairly sure coverage is out) or do I have to go the whole hog and spend £90 on a new battery?
iBook 12" 1.2Ghz Mac OS X (10.4.9)

I imagine you have already checked to see that your replacement battery wasn't also recalled. But you might check and be sure how long ago you got it and how long the warranty is--very possibly it might still be under warranty. I think you can find all this out by calling the Apple store, as they can look up your account. They might also be able to tell you how to report this to Apple, as it might be indicative of another battery problem that they may not know about yet. I think these batteries are actually manufactured by Sony and others, and if there is a defect, the manufacturer--and not Apple--will bear the cost of repair or replacement. So Apple might be willing to help you here. It's at least worth a shot. Apple likes to have happy customers.
Good luck!

N73 BATTERY BP 6M BATTERY HEATING DURING CHARGIN...

N73 BATTERY BP 6M BATTERY HEATING DURING CHARGING AND DISCHARCHING WITH IN HOURS FROM CHARGING ITS SIZE IS ALSO INCREASED

Please replace your battery with new one RIGHT NOW. Continue using this BP-6M may cause danger.
Usually turning heat while charging is normal, especially when charging in big current. And after the battery get older and older, the internal resistance will incrase as well, and this will generate more heat while charging. However, if the battery gets very hot while charging, much hotter than before, or suddenly become hot, you need to pay extra attention to it, 'coz this is a dangerous signal that saying your battery may have problems.
BUT, if a battery becomes to discharging quickly, in most case you need to replace it as quick as possible, for there may be slight short circuit inside it. If you continue using a battery in this condition, the level of short circuit may increase and at last, it may be totally short circuited and EXPLODE or BURN.
You've said the size of your battery is also bigger than before, so I can 99% sure that, your battery is no longer usable, REPLACE IT RIGHT NOW and handle it properly.

What does it mean "Battery Health" Check battery in the battery menu bar?

Check the full status by going to the apple in the left side of the menu bar, About This Mac, More Info, System Report, Hardware, Power and see what it says about the Cycle count, Battery Condition, Battery Capacisty, charge remaining.
Condition should be Normal or there is a problem
Ratio of charge remaining to cpacity should be close, round off, to the reported battery charge percentage.
Cycle count tells how many charge cycles the battery has been through, typical lifetime cycle count for a current generation battery is 1,000 cycles.
