Since last week, my batt has lost just about 1/2 it's charging capacity. What happened? I guess that it eventually had to happen, but this precipitous drop was a little much. As it was, it maxed out @ 1h10-15 mins. Now, as I unplug it, I get anywhere from 30-40 mins (abs max now - closer to lower end). Very bummed about this... not trying to buy a new bat - although the unit is so worth it - but they cost just about $300! Was looking to join the AL Club house anyhow, but boo... is this how the end starts? Used batts are the hardest to buy (esp online). Oh well, just venting.
