Hi,

Looking to buy a base 13" MBPro from 2/2011 with 141 Charge Cycles and a full charge of about 5347 mah. Does that sound reasonable for its age? Is it still a good battery (at least based on that)?

Thanks,

Sam

If you're not already doing so, use iStat Pro (free) or iStat Menus ($16) to get accurate readings of your battery health and cycles and computer uptime, among many other things. A forum member has posted a copy of iStat Pro that has been "tweaked" to enhance compatibility with Mountain Lion. You can download it here.

It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

Thanks though I looked through that already. I don't have the computer to run tests hence why I was asking.

Got it. Now that I re-read your post, I see that by "looking at" you mean you're looking to buy, not describing one you own. That capacity is roughly 92% of original, so yes, it's fine.

Sorry, it was worded confusingly. Thank you so much!

If it helps, my MBP (in sig), 3/2011, has 121 cycles, and 97% health.

These new non-replaceable batteries appear to last FOREVER, so I wouldn't worry about the number of cycles, unless it was up over 300.

They are SUPPOSED to last ~1000 cycles, with 80% health.

Non-Replaceable battery? I had the bottom off of my MBP upgrading the RAM, and the battery looked like it was replaceable. Can someone verify this information? Thanks.
 
The battery is not "User Replaceable" so if you replace it on your own, you void your warranty. Apple does not sell the batteries to end users. Apple is only charging about $20-$30 above what a user replaceable battery costs through Apple.

The built in battery is good for about 95% or the people with 6-7hrs+ of battery life.

Good news. It looks to be easily user replaceable.

And if under warranty I would send to Apple. But after the one year you can do it yourself. Keep in mind some of the AppleCare info on battery replacement is depending on issue with the Battery. I called Apple and got a generic answer. What I got from it was if it was worn out via use it is not under warranty. Only if there is a defect.
