It seems like RVers always need to store a vehicle or two. It may be your motorhome going into seasonal or long-term storage, a car that won’t be driven while you are away from your home base or a motorcycle that’s no fun to ride in the winter. Wouldn’t it be nice to be able to keep the engine-starting battery in those vehicles properly charged while you are away? Enter the Schumacher 1.5 Amp Speed Charge Battery Maintainer
This charger is designed for storage maintenance of any 6-V or 12-V lead/acid battery. It provides a regulated trickle charge to keep a fully charged battery topped off. It is not designed to recharge a depleted battery, but it compensates for small parasitic loads and the battery’s natural tendency to self-discharge over time. It also provides LED indication of charge status right on the front panel. The charger comes with a set of battery clamps and an additional cable with ring terminals to allow you to permanently install a charging connector on the vehicle’s battery.
I actually own five of these chargers and use them on my motorcycles, RV, truck and lawn mower. They are extremely well-built and reliable. Mine are four to five years old. I have also found that keeping one of these chargers on seldom-used vehicles will extend the life of the battery significantly. If you need a trickle charger, this is the one (or two orthree) to buy.
