Kind of a silly question but I was looking to buy a battery replacement for my macbook pro. See signiture. My macbook pro uses a lithium ion battery. I noticed that eBay sells the same battery but in a lithium polymer type. Would it work in my computer? What is the difference really anyway? Should I assume that the lithium ion gets 300 cycles and the lithium polymer gets 1000 cycles. I know thats with the new uMBP but what about the aluminum MBP?
View 7 Replies View RelatedI've been having with my 500MHz Ti Powerbook. It has been acting very temperamental during startup where it will not startup at all, the fan will come on but no screen, or it will chime twice (and it's a weird sounding chime) and not startup, or it will freeze after logging in or during the log in stage. I got it to boot up once, but since then... it's dead. It will not startup. A friend tells me it's the internal lithium (PRAM?) battery that needs to be replaced
View 2 Replies View Relatedthe PRAM battery clearly is failing fast. After two assurances from a large local computer seller/repairer (Best Buy) that they could indeed go to her apartment, and after acquiring the correct battery for her, I have now found out that they won't go to her apartment because the computer is more than six years old. Dead end there! Does anyone know of a place in New York City (or an individual) that would both visit her apartment and be sufficiently conversant with the innards of such an old Mac that there would be a good chance that the battery will be replaced without harming the computer? There doesn't seem to be anything wrong with it besides the failing PRAM battery, but Barbara is willing to pay handsomely to have her baby fixed, even if it means having the person go over it with a fine-tooth comb and charging accordingly. The computer is extremely heavy, or I'd take it in to the Best Buy store myself, and though we could get it into a taxi (with help from a doorman), there is the problem of getting it into the store and downstairs, where the repair area is. I'm strong but probably, not strong enough to do it, and we don't know anyone who could help. Any thoughts? There are multitudes of repair places and individual repairers in NYC, and many who visit people's apartments, but we clearly need someone who knows very old iMacs intimately and is not afraid to approach the problem.
View 6 Replies View RelatedI have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!

View 6 Replies View RelatedI've owned my Air for about 4 months now, and on the rare occasion that it sits unused for a few days, I always find that the clock has reset itself to something like 1-1-08. I'm guessing there's an internal battery to blame?
View 2 Replies View RelatedMy battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
View 4 Replies View Relatedi have a 13" mbp with 130 cycles an i use it extensively.its been about 6 months since i bought it and i noticed tht apple will cover my battery in warranty fr one year only if it has less than 300 cycles on it.
my problem is tht i typically use my laptop fr no longer than 4 hours at a time. which means i recharge the battery jus before the battery meter hits red an counts 1 cycle as complete.thts why i got less number of cycles on the battery
cn i continue doing this without any adverse effects to my battery and its life ??
I get the whole part about that I set my laptop to go to sleep in 5 minutes, and if I close the lid it'll go to sleep, and the little light at the bottom starts to pulse, etc. But in sleep mode, my battery seems to drain extremely fast!
For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!
If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.

I have an early 2008 non-unibody MacBook Pro. For about a year now, the status of the battery has been "replace soon." I was still getting a pretty good amount of time off of one charge so I wasn't too worried. This past Saturday morning, I woke up, checked the battery indicator lights on my computer (it had been sleeping since the day before) and it said it had about 60% percent so I opened it. I was on the Internet for about 10 minutes before it shut off without warning.
It wouldn't turn back on when I pressed the power button, so I plugged it in and it turned back on. When I checked, the battery status was "replace now." After using it, I turned it back off and left for NYC for the weekend and didn't bring it with me. When I got home last night, I plugged it in and tried turning it on with no luck. The battery indicator light was flashing one light, so I just assumed it would need to charge for a bit before it would turn back on. After about two hours, when I went to bed, it still was flashing just one light. I kept it plugged in over night, and this morning when I checked it, the battery indicator lights showed that it was fully charged, but it still wouldn't turn on. I still kept it plugged in throughout the day just in case, but it still won't turn on even though all the lights are lit. Is the battery just showing me false information, or should I be worried about more than just the battery?

purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?
i just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.
-What can I expect if just doing normal every day stuff (web surfing mostly?)
-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?
I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.
Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.
been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.
I just got a Mac Pro Octo 2.93. It has a 4870 card and 4 1tb drives. I also have a Sonnet E4P e-SATA card installed. Would a 780 Watt 1200 VA surge suppressor be enough?
The other question is about waking the computer up. My old G5 Quad (7800 GT card, E4P card, 2 500gb drives and 8gb RAM) would wake up and while the afore mentioned surge suppressor would beep, the room electrical breaker wouldn't be tripped. Using that same suppressor for the Mac Pro results in the breaker being tripped when the computer wakes up. Would getting a bigger suppressor help with this? In other words, does a unit with a bigger battery capacity allow the battery to take the extra load when the computer wakes up preventing the breaker from tripping?
I'm not sure if this is SL related, but I get the service battery warning when I click on the battery status. iStat reports it at 62% health. Rev B 1.6 just 6months old. Should I bring it to apple or is it just a bug of SL?

So, I randomly clicked on my battery and noticed this "Service Battery" message. I had never seen it before. Obviously, this isn't a good thing. My Mac is 3 and a half years old so I'm not surprised this message poped up. So, I opened Coconut Battery and noticed my current battery capacity is at 65%. Even though charger says it's green, my battery isn't even charging. Should I make an appointment with Apple? My AppleCare expired so i'll have to buy a new battery when the time comes. I'm sure they're not cheap, either.

I calibrated my MacBook Pro battery and then noticed that the battery life seemed slightly shorter after that. I calibrated it according to this: [URL]
Just wondering if I have done anything wrong...
One more question... What do they mean by "At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep." Does it mean that I have to use the computer until it just shuts down or should I shut it down once the "Low Battery" warning pops up?

I want to get a battery backup for my PowerMac G5 dual 1.8ghz PPC, but the numbers confuse me. the UPS selector tool on APC's website suggests I can get away with one that runs at 800VA.i dont need it to last long, I'm really just looking for something that will protect from surges, condition the power, and give me enough time to shut down in case of a power outage. I wouldnt need more than a few minutes, and I dont expect more than a few minutes power supply.

View 4 Replies View RelatedI have got a macbook pro with 2.2 ghz AMD 6750 graphics card. Its around 8 months old. The battery used to last around 4 hours but recently I get around only 2 hours. I have tried to change settings in energy saver to improve battery life but its still the same. I ve noticed that when it shows AMD graphics in about my mac, it takes more battery life. So, I guess its using more battery at that time. Ive read it switches automatically depending on the task but is there anyway to change it in settings?
Also, how is it possible to get the best possible battery life? Should I keep charging and discharging it every now and then.? Currently I unplug the adapter as soon as it gets fully charged and the battery last for over 2 hours (surfing, listening to music, half an hour of video).
