Many of us have that spare battery lying around the house for that "just in case" spare. Or perhaps you have a vehicle that you only drive every once in while, or a classic that only goes out on those summer days, but never in the winter. Whatever the case, these chargers are designed just for these purposes! Maintenence Chargers are used to give a trickle charge (Slow charge over time) to batteries, so they stay charged while sitting around for periods of time without use. Small and compact, they can be mounted upon the wall or even inside your vehicle. All Battery Sales and Service Online strive to suit all your battery and accessory needs at low and competitive prices, so come browse our selections, and allow us the privilege of your business.
