Battery Accessories

What types of battery accessories do I need for my RV?

The basics every RV owner should have on hand are battery cables and terminals, battery boxes or trays for secure mounting, terminal cleaners and corrosion protection, hold-down hardware, and a battery disconnect switch for long-term storage. If you store your RV through the off-season, pair these with a winterizing kit to protect the rest of your systems at the same time.

How do I prevent corrosion on my RV battery terminals?

Corrosion forms when battery acid vapors react with the lead posts and copper cable lugs. Clean the terminals with a wire brush and a baking soda solution, dry them completely, then apply a terminal protector spray or felt washers before reattaching the cables. Inspect the connections every few months, more often if you boondock or run heavy 12-volt loads.

Will these battery accessories work with both lead-acid and lithium RV batteries?

Most cables, boxes, hold-downs, and disconnect switches in this collection are compatible with standard Group 24, 27, and 31 lead-acid, AGM, and drop-in lithium (LiFePO4) batteries. Confirm the amperage rating on disconnect switches and cables matches your battery bank's max continuous draw. If you also need shore power connection hardware, see our RV plug adapters and Southwire Surge Guard surge protectors.

Do battery accessories ship free?

Yes. Battery accessories ship free on orders over $100 within the contiguous United States. Smaller hardware items typically ship via standard ground in 1-3 business days.
