I bought a battery for my t-mobile MDA (htc 8125) smart phone. I waited for my dying battery to kick the bucket and then I charged up and started using the battery from BargainCell. It started to die immediately. A month and a half of light use and the battery is totally dead. It won't take a charge.Their customer service told me to get bent. I'd take your business elsewhere. BargainCell batteries sell defective stock.
