I was curious what the battery reading was at full charge and once discharged (when the ipro shuts off). The charged reading was what I expected at around 4.2v. The discharged ready has been right around 3.3v but one of my batteries was reading 3.7mv?? I put an X (so I know which one it is) on it are did a recharge and it came back up to 4.2v. Let it sit overnight and it still read 4.2v. I put it back in my PV and it lasted a couple of days and when it shut down the marked battery was back down to 3.7mv. The battery has only been charged 3 times but should I toss it??
