Took a chance on a new old stock Apple Li-Ion on the 'bay, for $20, as I had bought one a couple of months ago and it came back to life very nicely. This one, not so much. Any advice from anyone re info below?
Battery is recognized; can charge; charge drops from 100% to 0% in a matter of about a minute (can't get through a full boot, for instance). I have cycled charge-discharge about 6 times now after giving long, full overnight charges. The full charge capacity of the battery keeps dropping as shown in the system profiler. It has gone from showing 4500mAh to 2452mAh now. When it charges, it goes slowly from 0% - 5% and then jumps to showing 100% very quickly.
Any benefit in keeping at the charge-discharge method, or is this one toast?
I assume the "freezer overnight" method is only useful for NiMh batteries, not for Li-Ion?
I'm quite honked at the seller, he had two return policies in his listing and I only saw one of them. I've been mostly fortunate with eBay, but this was a case of a dirty seller. Battery probably had high heat exposure at some point and so it's n/g.
