Instead of throwing out dead batteries, recharge them with the Battery Recharger! This clever device reduces battery waste and saves you money by regenerating the charge in AAA, AA, C, D and 9-volt sizes. The Battery Recharger lights up while charging; a built-in timer shuts it off automatically after your batteries have charged for 24 hours. The Battery Recharger also allows you to charge different sizes of batteries at the same time. Simply plug this battery recharger into a household wall outlet; it works with alkaline, NiMH and NiCD batteries. Note: only one battery chemistry can be charged at a time. Do not charge alkaline batteries with Ni-CD batteries, alkaline batteries with Ni-MH batteries or Ni-CD batteries with Ni-MH batteries.Charge dead batteries for flashlights, decorations, LED candles, toys, portable radios, solar lights, and much more. Auto shut-off timer turns the battery recharger off when batteries have charged for 24 hours. Built-in indicator light shows the Battery Recharger is working.
