Those batteries are used in home cordless phones, laptops, and older cell phones. Basically to have a chance to re-condition them is to drain them completely (turn off all power-saving features) and then fully recharge them. If the first time it doesn’t work then try two more full discharges and recharges. Not using it at all during this process. If the battery is still bad after this then it has developed a memory that cannot be erased easily. As to on the charger all the time, most laptops (and home phones) will stop charging the battery once it is fully charged. Leaving Ni-MH and Ni-Cadium batterys charging all the time can hurt them and make them develop a memory. If you have a Li-Ion battery, which is what is used in all modern cell phones and some laptops, then leaving it on the charger all the time will not hurt it at all. What hurts Li-Ion batteries is letting them die out completely. This works if it is a Ni-MH or Ni-Cadium. Those batteries are used in home cordless phones, laptops, and older cell phones.
