Do your batteries stay charged when left in the charger?
A co-worker has a 14.4v drill that he uses very infrequentley. lets say once a month. He keeps the battery in the charger. When it's time to use it, the battery has no charge. He has changed batteries and chargers and he still has a problem.
Do the chargers shut down after the battery reaches it's charge? Does the charger monitor battery voltage after a charge? It seems I remember that car chargers monitor battery voltage and automatically start recharging.
Thanks in advance,
Bill
