Use the finder on this page — it adds up the draw of the units you select, multiplies by your hours on the water and recommends a battery with headroom built in.

Screens rated for 16V run at the top of their voltage range for the whole day rather than dimming as a 12V bank drops. Confirm your units are rated for 16V before wiring one in.

LiFePO4 — lithium iron phosphate — is the most thermally stable lithium chemistry in common use. Compared with lead-acid it holds voltage under load far longer, weighs a fraction as much for the same usable capacity, and needs no watering or terminal maintenance.

Group size describes the case dimensions and terminal layout, not the capacity. Match the group size stamped on your current battery — every product page lists the group size and dimensions so you can confirm it fits the tray you already have.

A lead-acid charger can undercharge a lithium pack and shorten its life. Use a lithium-compatible charger — everything in our Lithium-Compatible collection is profiled for LiFePO4.

None of the routine watering or terminal cleaning that flooded lead-acid requires. The built-in BMS manages charge and discharge protection automatically.

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.

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.
