I Bought 2 for my palm pre 2. Ran dr battery program and they have a max of 83 and 87 percent. Seller said they were new so my question is do they need to have a few charge cycle to calibrate properly cause my factory one said 100 percent after the first charge or is the seller lying. He had 100 percent positive reviews but i suspect other phones he sells batteries for dont have a program that is that easy to check battery stats on or people dont bother. They were only four dollars each and match my palm battery exactly so they arent knockoffs best i can tell.
