Frequently Asked Questions
Fitment & Compatibility
How do I know an accessory fits my battery?
Match the group size first — trays, boxes and hold-downs are sized to a group number, and every product page lists the one it fits. For cables, match the gauge and length to the run you are wiring.
What cable gauge do I need?
Heavier current and longer runs both need thicker cable. Trolling motor and cranking circuits want heavy gauge; accessory and electronics circuits need much less. If you tell us the load and the run length, we will size it for you.
Do I need a battery box or a tray?
A tray holds the battery in place; a box encloses it as well, which is what you want where terminals could be contacted or where regulations require covered batteries. Both are sized by group number.
Warranty & Support
What warranty comes with these batteries?
Terms vary by product line — the term for each battery is listed on its product page, and the full details are on our Warranty Information page. Register your battery online after purchase to activate coverage.
What if I am still not sure which one to buy?
Call our US-based battery team on 1-800-827-3232 before you order. Tell us the machine, the tray you are working with and how long you need to run between charges, and we will point you at the right part number, or message us.
