Hey all, I was hoping to get some advice on my MBP battery situation. I have 15" MBP (non-unibody) running 10.5.8 and battery update 1.3 that is around 18 months old (so it's out of warranty) and was purchased as a refurb. Like a chump, I paid poor attention to my battery, including leaving it plugged in pretty much constantly and not cycling it regularly. Anyways, I never really noticed any issue with its charge up until a few weeks ago when I could tell a big drop off in its charge time off the power supply. I checked iStat Pro and sure enough the battery's health had plummeted to around 30 percent after 76 cycles. The charge remained 100 percent. I tried to cycle it a lot over the next few days or so, but the problem only seemed to get worse and now the health is at around 15-20 percent and the charge 97 percent. Knowing the MBP battery reputation and my poor handling from the get-go, I am resigned to the fact I'll need to get a new one -- but I was hoping to see if anyone experienced a similar drastic drop and if maybe this could be more than a defective battery? Any help or advice is greatly appreciated... thanks!
