We've all scrounged for old batteries from game controllers, toys, or clocks to put in the remote or baby monitor. Thus, a battery charger starts making sense, as it prevents this annoying hassle. Having a charger means having recharged batteries on hand and no more running around stealing batteries from other units.
While there is an initial outlay for a good quality battery charger and reliable rechargeable batteries, the savings accumulate quickly. Recharge your batteries and alleviate the stress of battery hunting with a rechargeable system.
