On Topic! Is this MBP battery OK?
Posted by: lost in space
Date: February 24, 2020 07:29PM
I bought a 2009 13" MBP from one of our brethren here a few years ago for my wife. We've been happy with it. I believe she's been pretty good about keeping it plugged in- it shows only 94 cycles on the replacement battery, which has a mfg date of May 2014 and status of 'Good' according to Coconut Battery. It runs down in about 40 minutes running a movie in FF, though. I don't have much laptop experience, so I'm wondering if that's normal for a battery of that age. We're on the brink of upgrading to something like a 2014-early 2015 13" MBP Retina or putting in a new battery. Just used for Word, email, and sloshing around the web. Any thoughts?

A really good battery can last 6-7 years, but this is pretty normal for an avg battery. Any useful life past three years is gravy. I bet it smells like rotten fruit (meaning that there may be a tiny leak)

I suppose I should mention the battery is from our sponsor. So 6 years is a good run for a battery, then?

6 years is a GREAT run for a battery.

Ditto, 6 years is more than solid. You did just fine. That's what I've done with the wife's '09 MB and my mid-'10 MBP...just replace batteries and upgrade RAM/drives 'til something unrepairable (or just impractical to fix) makes you give up the machine.

I would not buy (or frankly, trust) any other non-OEM battery than OWC's Newer brand. Been buying them again and again since they came out way back in the day.

It's not unusual for video to knock hours off your battery life.

How long does it last when you're just browsing the web or checking email or word-processing?

I let it charge overnight, then ran it today FREE FROM BROWSING, unlike my mis-typed "battery life from browsing" two posts up. It ran for a bit over three hours, about a quarter of that time on a screensaver. Anyway, three hours from 100% charged to 5% is pretty good for a six year old battery then?

I think you're well over on the "good" side of the bell curve.

I wouldn't expect a 6-year old battery for a 2009 to break an hour.

My 2008 is on its 5th battery, latest one just a few months old and it gets 3hours if I go easy on it. (Maybe technically 4th battery. One replacement was DoA.)
