MBP Battery Health

Unlike NiMH and NiCD and losing voltage and raising internal resistance, LiPO and Lithium Ion batterys lose capacity every cycle. Even so, LiPO and LiON batteries are some of the best battery tech out there.

I use LiPO in my professional rc cars where a 5000mah 2 cell LiPO will be drained anywhere between 10-30 minutes running modified class. You have to watch where the batteries come from. Some get 20 cycles before the capacity drops, but from the good mfgs, you should get 200-300 before capacity starts dropping. Also, if your battery won't hold a charge anymore, dont keep it!!! Thats utterly dangerous.

In the rc world, if a battery gets puffed up or we have to toss it because you can't put enough energy back in, you slice open the cells, and drop them in a 5 gallon bucket of salt water for 1-2 weeks, then toss in the trash (don't worry, its completely safe then)

I need to research which plant Apples cells come from. I believe there are only 3-4 great quality manufacturing plants, some are acceptable and some are even completely dangerous. Just imagine how much energy is stored into these things. The fires are quite fast and fierce, but usually over pretty quickly.

Actually its not the most dangerous, its just a different type of "explosion" NiMH and NiCD are like little grenades, but can take more abuse. I had to toss a soft case lipo because I picked it up with to much force (squeezed too hard when pulling from my vehicle) I made a dent in it with my fingers. That was a $100 battery that I had to dispose of after only 3 cycles.

I am dissappointed by my battery life.

86% in 21 cycles and I have performed 3 calibrations. At what point do I hit the Genius Bar?

I'd be okay with it if I could get more than 2 hours of WiFi use :(
 
What the heck?? Now it says 1108 mAH (20%) from the original 5500 mAH, and only 5 cycles. It's dropped over 30% today!

Bad battery?? Is this covered by Applecare?
 
My System Profiler indicates 117 Cycle Count

Coconut Battery indicates 4 Cycle Count

Furthermore, my Battery Life is up to 91% now...this program would seem to be worthless on 10.5.1?!

edit: coconutBattery thinks I am plugged-in when I am no where near the power and visaversa?

iStat Pro says mine is 99% at 45 cycles? Could that be right? Seems too high compared to everyone elses.
 
I'm at 47% health after 87 cycles. My MBP is only 6 months old. Would the standard Apple Care 1 year warranty warrant me a new battery if I went to the Apple Store?
 
You know what they say... A cycle a day keeps the doctor away.

47 cycles/98%.. had my MBP for almost 2 months.

You should check to see if your battery was recalled. I say this since it's a Sony battery and your computer is the right age.

Could you please show me where it says that? It would be great to have this when you discuss with applecare.

so sorry! i lost track of this thread and youve probably found the site now. so im just replying just in case you havent found it or rang applecare yet. says it under battery lifespan here
 
I think I have a serious battery problem. Coconut battery says my battery capacity is 1842 out of 5500 with 5 cycles. My power settings says I have 26 cycles. However, my capacity has dropped significantly. :(

I'm looking at 94% at 61 cycles.. and I've had this for just about two months.
 
DONT take the battery out while using it plugged in. Apples computers are designed to use some of the battery while plugged in. If you take out the battery your computer is not getting enough energy to run properly.
 
"DONT take the battery out while using it plugged in. Apples computers are designed to use some of the battery while plugged in. If you take out the battery your computer is not getting enough energy to run properly."

LOL. No, just no. Not true at all! They use more power with the battery in - to charge it.

off topic what is your rc car model?:D
I have a Tamiya TNX 5.2 and this car is a beast..but its loud and heavy.. in Germany the nearest nitro car track is 100 miles away..but if i had an electric car i can use one just around the corner :cool:...so i'm thinking about switching to electric
 
After a year and a half, my MB battery health was 67% and 161 cycles. I called up Apple and they overnighted me a new battery for free! I just have to mail back (postage paid by Apple) my old one or they charge me for it.

If anyone is under 80% health AND under 300 cycles, call Apple! You will get a new battery.
