Found this interesting article at Mobile Crunch that provided a link to a chart. The chart lists a handful of TP2 batteries and it results. According to the chart, my battery made by Andida is BS. I got mine on ebay for $9.99 claiming a 2000 mAh- but according to this test, the actual mAh are 1101... Funny thing though, with the original OEM, 1500 mAh, Touch Pro 2 battery (which tested at 1414 mAh), I have to charge it about 3 times a day. And with the Andida battery only once. I got way better results with the Andida battery. Compare yours. Or if you are in the market to buy a new battery...this chart is helpful.
