    Battery charge in excess of stated mAh rating - need advice.

    I was charging a 4200 mAh 3s LiFe battery and my charger showed 4400 mAh and it was still charging. Normally this battery peaks at 10.80v (charger showing mAh <= 4200) and this time it was only showing 10.67v (charger showing mAh = 4400).

    No sign of puffing or damage but I stopped charging the battery for saftey reasons and thought I would ask for advice.

    I do not run a lvc with my LiFe but have never seen this happen. I have read that LiFe cells shouldn't fall below 2.4-2.5v threshold. My battery showed 7.85v when I put it on the charger so I didn't run below spec.

    Should I put it back on the charger and watch it closely? Any thoughts on why the charge is exceeding capacity?

    This type of support must be handled by the manufacturer. They will be the best source for correct information.
