Most new older style rechargable batteries need to be conditioned first
before regular use.They should be fully charged up and then put in a
flashlight and leave the flahlight turned on untill the batteries
completly drain down and do the same thing again a couple of times or
otherwise they will devlope a memory and will not fully recharge
again.Once a month,they should be fully drained down again and fully
recharged at least once to keep them in good working condition.NiMH and
some other types of rechargable batteries are different and do not
develope a memory.Always read the instructions that came with the
rechargable batteries or the battery charger.
