I got this dynamite ac/dc twin peak charger and ive hardly used it sence i got this other charger in a trade. This charger is only 6 months old and ive only used it 3 or 4 times. This charger will allow you to charge two Ni-MH or Ni-Cd batteries at once. It is equiped with a advanced peak detection circuitry protects batteries for being over charged. This charger will charge 4/5 cell reciever packs and 6/7 cell car packs. Has two differant types of lead adapters. Uses AC or DC power, so you can charge from your car battery or wall outlet.
