I bought a 3rd party battery for my MBP. I put it in and after cycling the battery i noticed that the full charge capacity was only 3990mAh (supposed to be 5500mAh). I returned the battery today and got and an upgraded replacement. this shows the full charge capacity at 4995mAh (supposed to be 5600mAh).
is this normal. Do I just need to give it some time or is it something with the batteries.
I received my new 15", i7, 128gb ssd, 8gb ram macbook pro on april 19th. I love it and have no problems. Have any of you guys noticed that the full charge battery capacity, which is found under system profiler-power, varies often. When I first got the macbook pro the full charge capacity of the battery was around 6830. Now with each charge it seems to go down slowly. At first it jumped from 6800 to 6600 and now stays at around 6520. Is this normal?

I have a 1.67 GHz Powerbook G4. This morning it was fine. When I got home from work, it decided that it suddenly no longer wants to stay on when not plugged in. The battery is showing a full charge. The light on the plug is green. But the second I unplug the cord from the laptop, the entire thing shuts down.
View 6 Replies View RelatedI noticed that the full charge capacity for my mac varies. On first charge it indicated 6580mAh, then on second charge 6685mAh(which the software indicated that I was able to fully charge to this capacity), then now after I unplugged it for a bit it now says the full charge capacity is 6850mAh. I'm planning to calibrate my battery on this discharge.

Late 2008 refurb Macbook Pro, 2.53ghz, Windows 7 RC (therefore forced to use the 9600 at all times). According to this report, the MBP got around 3&1/2hrs of run time with a dimmed screen and watching videos. From a full charge, I start browsing the internet (no videos at all), and my battery reading read as follows
91% 1hr, 16mins
90% 1hr, 20mins
89% 1hr, 24mins
87% 1hr, 23mins
Not only were the readings all over the place, but even from a full near charge I wasn't even getting an estimate of 2hrs, while Apple advertised 4 for the late 2008 model, and the review I linked to says they got 3&1/2. Do I have a bad battery, or does simply running the 9600 reduce the battery life by such a drastic amount? I have already calibrated my battery following the guide on the Apple website.
My wife's Macbook 2.1 is acting strangely. The Battery indicator led's are full (green) the charger led is also green and the software shows 100% battery is charged. After a couple of seconds after disconnecting the charger it switches off. I've tried resetting the SMC and this allowed a full nights use without the charger but on the next day it went back to only holding for a couple of seconds. I don't want to have to reset the SMC every day. It's running on 10.5.8 and is all up to date.

Then I can reboot work for half an hour until battery is like 50% then it shuts off again... then I can reboot again and work for some more time. I've checked with coconut battery and when the computer stops at 70% I still have like 1700 mAh...I've reset PRAM, power management, etc...
Of course my battery is old, but it should work until 00%... not stop at 70%. Before I spend like 100$ (that is what a macbook pro battery costs here in Mexico) I'm willing to try anything...
I have a Week 01 MacBook Air, and I just started to notice that my MBA has not been performing its best since I bought it.
This morning I at 0745am, but now its 0831 and my battery is now at 53%; is there something wrong? I took a stopwatch and averaged it at about 53-55 seconds where the battery will drop 1%.
According to coconut battery, current battery capacity is 4670 and original battery capacity is 5090, and the system profiler says that I'm at 31 charge cycles. And YES, i've reset the PRAM, PMU/SMC, and calibrated my battery
I have a 1.33Ghz 12" powerbook and recently it has started to just shut off when the battery is saying it has around a half hour left, instead of it warning me that the battery is low and it will go to sleep soon. and then it won't restart until I plug it in. is there any way for me to fix this besides getting a new battery? This battery is not covered under any recalls, and there is no applecare left on the computer. also if it matters the computer is running 10.4.10.

View 4 Replies View RelatedBasically I'm having issues with my newly acquired Powerbook G4. When i bought it the battery was not working at all so have now installed a new replacememnnt battery which works fine but having some slight issues. So...
First time I charged it, it reached 100% but green light never came on to indicate full charge. When I run the PB off the battery it gets to 20% and it shuts down without any warning it's low on battery (trying to switch it on after this is impossible, it clearly has no life) After the above I connect the power lead and start up the computer, the battery indicator starts charging from 20% onwards. Something fishy definitely going on and I have no idea what it could be, I calibrated the battery but it has always cut off at 20% since first charge/discharge.

I have a MacbookPro mid 2009 and have some problems with my battery. This morning I noticed that the battery was empty through it was supposed to be in sleep mode during the night. My battery has 97 cycles and has 99% of its original capacity. What could be the cause of this problem ?
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 RelatedIf 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.

View 1 Replies View Related 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?
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 want to make sure nothing else is wrong with my Macbook..have never replaced the battery in 3+ years...Always says not charging and once the magsafe is removed Pro shuts off...is completely dead battery the only problem..?

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 check my HD and it was almost full to capacity, it shows I had 2.2 TB of photos and 1.5 TB of audio.
I don't know if this photos and music kept adding each time I sync my iphone or each time i log on to Facebook.
Anyway I would like to FREE UP THE SPACE but how, and would I need to have 3plus TB of external DH to do this, or what??????
