I too wish I'd have researched complaints before buying here. I thought HP was overcharging for laptop battery replacement, so I bought one from this place at half the price. First, it didn't fit right and I had to file down some edges, but it worked. But after about 9 months it can't hold a charge (runs max 30 mins.) and the HP battery test says it fails. No savings in the long run. Buy a good battery instead and treat it right, it'll be a better deal (I left mine sitting in the docking station way too long, it only lasted 2 years). read full review »
