Battery Tender will keep the power flowing

At the end of a long winter, you're probably eager to get your RV back on the road. Your trip could be cut tragically short by a dead battery, though. After months of disuse, batteries will flatline, leaving you with a vehicle that can't go anywhere - keep it fully charged with a Battery Tender.

This device allows you to maintain proper storage levels in virtually all types of batteries. The charging process is a simple four steps, after which you can rest assured knowing your RV will be good to go from day one. Your battery will maintain 70 to 80 percent power levels until you decide it's time to roll out.

The Battery Tender features temperature compensation to ensure an optimum charge voltage relative to how warm or cool it may be, and is spark-proof, even if leads accidentally touch.

"My truck, which is used for towing a trailer, does not get used often," writes one Camping World customer. "When the truck is not going to be used for awhile, I hook [the Battery Tender] up and no longer have to worry about it starting right up."
