Replace Backup Battery

My installer put the backup battery in the attic. I'm disabled so I don't stand a prayer of getting up there to replace the battery. What do I do when it's time to replace the battery? How do I know the battery needs changing? What's the average before a battery needs to be change?

Mine began beeping about a week ago. I could find nowhere on the general website that addressed this problem--even in the automated help (i always got remote control battery replacement...not helpful). Nor was i initially able to get real, live tech support. This morning i got through and was advised consistent with this string: ie verizon warantees the back-up battery for one year only; after that it is your problem. the website is:
fios.asurion.com
please note: there is no www. before the address.
there are only three tabs on the website: home; order; log-in.
the battery at this time costs just under $50.00 (not sure what shipping is).
I am pleased with Fios (though the Verizon customer support website could use some help), but charging you 50 bucks to replace the battery is something not even the cable company would do.
note also: the back-up battery powers only your phone service in the event of a power outage (according to tech support; no internet, no tv). So...i thought (and was advised by tech support) i could just take out the battery to get rid of the beeping...didn't work.
hope this helps you avoid what it took me to figure out.

Backup battery replacement specifications

I have scanned MULTIPLE pdf manuals on replacing the FLAT backup battery in the 17" iMac G5 with the ambient light sensor AND NOWHERE DOES IT TELL YOU WHAT KIND, TYPE, SPECS, ETC. It just says replace it with the new one.. well duh!
There was no battery under the little clip for me to compare it to otherwise I wouldn't have a problem. In fact, I don't understand how the machine was working before since it had been working perfectly fine a couple days ago. I cracked open the case to replace/upgrade the hard drive and when I put back together unit will not boot. Cracked open the back and that was when I noticed the little flat battery compartment was empty???????????
I have replaced those little 3.6v purple backup batteries for 20 years. Why didn't they just stick with SAME BATTERY they have used for over 20 years

The battery is a CR2032 3 volt lithium button battery that you can find for about five dollars in any Radio Shack.

How do I open the door to my Optical Network Terminal (ONT) to replace the backup battery

I have an ONT that looks like this: http://www.verizon.com/cs/groups/public/documents/adacct/bbux400-open.jpg How do I open the door to it to replace the battery? Thanks Ben

My ONT BBU (Battery Backup Unit) looks just like yours. The door is where it says ONT 314 and Verizon.
On mine, I can just grip the edge of the lower right and corner of the door, under the lights and buttons where it says SOHO, and pull the door open.
That exposes the battery.

Replacement of backup battery

Where can I purchase a backup battery? Can I install this myself? If not, where should I go for the installation?
Thanks,

Hello,
Which model of T-series ThinkPad do you have? Knowing that may be helpful in determining which type of battery your notebook computer has and the associated replacement steps for it.

Backup Battery

I have an iMac G3 CRT, indigo. It won't hold date & time anymore. The help menu tells me I may need to replace the backup battery but I can't find any info on where it is or how to accesss it. Anybody got info??

Welcome Dale!
This is the battery as sold online:
http://eshop.macsales.com/item/Newer%20Technology/BAA36VPRAM/
Radio Shack stores cary the correct battery as part number 23-026, but will charge you three times the online price (the example I posted is typical).
If you open the RAM installation door on the bottom of the case, you can see the PRAM battery. A non-metallic grasping tool like plastic forceps makes replacing the battery easier. Make sure to note the polarity of the old battery and duplicate it when installing the new one.
Most PRAM batteries last a long time, but start to die quickly when the computer is off wall power. Best practice is to leave Macs plugged into the wall socket even if they are not getting much use. If you must unplug one for an extended period of time, remove the battery and tape it to the case.

Replacing CMOS battery on T21 notebook-anything that I should know?

Hi all.
New to this forum so I hope I do things as expected
I must admit that I am finding it harder to find relevant material on this site as opposed to when it was the IBM site. I guess that the dating of my T21 does not help either.
My poor old T21 needs to have the backup battery (CMOS) replaced but before I do that is there anything that I need to be aware of, like precautions to take before I unplug it and/or anything that I need to do after I plug the new battery in?
Any advice appreciated.
Regards Janset

Hi there tfflivemb2
Thanks for your reply. As it was it was not too late, I only received my new battery from the US today (ex eBay)
And you are right, that small screw driver is a definate must for the installation. IBM really did not think it through when they engineered the installation of the backup battery did they?
If they go to all that bother to make a capture device to hold the backup battery, why did they not incorporate the connector into that same capture device so as to facilitate things?
Anyway it is now done (after about 20 minutes of fiddling about) by this geriatric.
Regards

Backup Battery Replacement HowTo

Has anyone posted a picture, a video, or even a clear set of instructions for replacing the battery in the BBU? My battery is positioned behind a molded plastic "hold-down" ridge, and there's not a lot of room to maneuver it, or even remove the connectors.
TIA

HaroldWho,
This may not be the exact setup you have, but the same principle will apply:
1.) First, make sure the screw on the right-hand side of the battery backup has been removed.
2.) Once you have removed the screw, grab the left-hand side of the cover panel. There are two tabs that must be pressed in.
3.) Once the tabs are depressed, pull the panel out and then up.
4.) This will expose the battery. There is a tab on each side of the battery. You don’t have to pull these apart, simply turn the battery to the side and slide it out.
5.) Once you have removed the battery, disconnect the leads from the top of the battery.
6.) Note: This process is not accurate for all types of BBUs currently deployed, but is close enough for all but MDU and SOHO installations
Hope this helps!

Chris

Can I just disconnect/remove Fios backup battery?

I cut off my home phone service due to not needing/wanting it any longer a few months ago. Now the backup battery is beeping every few minutes. I assume that means it needs replacing. But it's also my understanding it's only for the phone. I now only have fios cable/internet services. I disconnected the battery and took it out, but that annoying beeping continues. I have even hit the alarm off button on several occasions but it still continues. Am I missing a step or something. I'm about over it and contemplating switching back over to the local cable provider Cox Communications.

People, when you reply to someone's post, do you even read it? He is stating the following:

I assume that he wants to know how to shut off the beeping. He does not want to buy a new battery or pull a cable off of a battery that is already out of the box! He just wants to stop the beeping, period.
My only suggestion is to take the box apart and cut the wire to the speaker (alarm), this will silence it for good. Otherwise, you will have to purchase a battery and plug it in to keep it charged.
Sorry for my little rant!

I did, in fact, read the post. The unit itself is causing the beeping (not the battery), and as I said, this is usually caused by the unit not receiving power. Remove the CAUSE, and the symptom should be resolved. I did not suggest anything to do with the battery itself.

Backup Battery Question

Hi
I've been asked to get a Titanium up and running which has been left in a storage cupboard for years. After reading through this forum it's becoming obvious that the reason it won't power up or charge the main battery is because the internal backup battery has run flat. I've tried a few suggestions such as resetting the PMU, leaving the power cord plugged with the main battery removed, etc, but after a few days of this I think replacing the internal battery is the only way I'm going to be able to revive the machine.
I've downloaded take-apart instructions and am fairly IT competent so I'm not put off by this, but I'm confused as to which battery part code I should order - there's three different ones for the Titanium. I don't have any documentation for this machine and as I can't start it I can only say it's the 500Mhz model with a VGA connector on the back.
Does anyone know which battery I should order?
Thanks =0)

Took the plunge and opened the case up - was able to get correct part number by searching on Google using code stamped on backup battery =0)

T410 - how to recharge backup battery after - ERROR 0251 System CMOS checksum bad

Hey people
I would like to know how to recharge the backup battery ( internal one, keeping clock and date etc. )
i got the
Error 0251 System CMOS checksum bad— Default configuration used.
message and after looking at the T400 manual they write what to do:
Charge the backup battery for more than 8 hours by connecting the ac adapter.
ok sounds good, but i cant figure out how to properly charge it,
do i need to put the normal battery pack out and then attach it to the AC adapter, or not?
Does the laptop need to be running or will it be charged also turned off?
i would really appreciate if u could help me out and tell me the proper way to recharge!!
thanks already,
cheers,
Andi

Hello and welcome,
I didn't know that the backup battery was rechargeable. I don't think it is. You might be better off to just replace it.
The Hardware Maintenance Manual page 80 shows how to access it. According to the System Service Parts T410, the FRU number is 02K7078. They should be easy to find and inexpensive.

Change backup battery or not?

I am in the process to replace the thermal module of my W510 machine. I have opened the cover and saw the backup battery. I am curious that is it a good time to change the backup battery? Do I need to change it or not? It is not that easy to open the cover like this. What's your advice?

Depends on the battery type. There are actually rechargeable types, so these will appear to last the life of the machine, or at least the time the original owner has possession of the unit.
If the battery is not the rechargeable kind, look for 2-3+ years. In any event, it's a good idea to change when the system is open if it is in a normally inaccessible area. as this will avoid any corrosion that may occur as the battery ages. Otherwise wait until the system looses it's memory <g>.
Interstingly, my Nikon has a CR1616 button battery, and it's been over 4 years now, and still working.

Type of battery -- mid 2010 13-inch macbook; and how soon do I need to replace dead battery?

I'm trying to replace the battery on my mid 2010 13-inch Macbook. I'm not sure what kind of battery I need to get, and can't seem to find any indication in "System Information". It's a "MacBook7,1" with Intel Core 2 Duo and Processor Speed: 2.4 GHz. I found this battery on amazon: "Apple MacBook Pro 13 Inch Mid 2010 Battery 60Wh, 5500mAh". Will it work? Do I need to get one with a particular power capacity, or anything like that?
I'm also wondering how quickly I need to get the problem fixed. My computer stopped working yesterday unless plugged into a power source. I don't really want to send it away to get it fixed, as I have a lot of work I need to do on it over the course of the next week. If I buy a battery online, wait for it to arrive, and install it (a process that will probably take at least 4-5 days), will I be leaving it too long? Or is it OK to continue just running my computer off the mains for now?
Thanks!

PS: here's some other info I found, after my earlier post timed-out:
See how a determined DIY user with some skills & abilities could dissect & replace battery:

Find an Apple Authorized Service Provider
Visit an Apple Retail Store
An Apple Store or Authorized Apple service provider could replace the battery
for the cost of the part, and a fee for the tech time. This may vary by location.
Hopefully this helps. The part is not considered 'user replaceable' but it is possible.
Good luck & happy computing!

After changing the battery in my iphone 4s, the phone will not boot up. I only see the apple and when it sits for a few minutes, a code shows above it. What is going on? Did I damage the phone by replacing the battery?

My sister gave me her iphone 4s for my son. It needed a new battery so, I bought one and replaced it. after doing so, it will not power up. I can only see the apple on the screen and when left for a few minutes.... 10 lines of numbers and codes show up at the top of the screen. Did I ruin the iphone by replacing the battery? Was a simple switch so I don't understand what is going on. Have never had one of these before.

iPhones are not user servicable.
Take the device to a competent repair person or buy a new one.

MacBook Pro 13 Early 2011 Battery Degradation to Not Detected, User Replaced New Battery also Not Detected, Please Help!

I have a MBP early 2011 13 inch and do not have Apple Care. After I installed Mountain Lion I noticed the battery health was dropping pretty rapidly, with a service battery warning. I tried resetting the SMC and PRAM and even a clean install. I took it into an Apple store and they said I should have cycled it more, but I could still use it. The health dropped and dropped until a battery would not even be detected. Because Apple would not replace it for me for free and I didn't want to pay for them to do so, I bought my own battery. Once I replaced the battery with the new one, it still says there is no battery connected.
When I detach the battery and then attach it again, the battery indicator lights on the side show 4 dots. When I plugged in the MagSafe connector, the fifth light started blinking (I thought it was charging) and then it went back to all of them blinking indicating no battery detected. The computer also automatically turned on when I connected the MagSafe.
I have tired multiple times to reset PRAM and SMC even after installing the new battery to no avail. I can use the machine with the MagSafe connected, but as soon as the cord is unplugged or bumped, it goes into the emergency sleep mode.
Any thoughts on what might be ailing this not yet two year old machine? My first Mac lasted 7 years before any logic board fail so I hope that is not it. Anything I should try that I haven't yet? Any ideas on what this might cost me through Apple?
Thanks!
