What battery does my boat or vessel need?

Boats need marine batteries that are resistant to moisture and salt corrosion. Deep-cycle AGM batteries are the most recommended because they can withstand repeated discharges and recharges without deteriorating.

What is a deep cycle battery?

A deep-cycle battery is designed to be discharged to 80% of its capacity and recharged repeatedly. It is ideal for boats where it is used as an extended power source. Do not confuse it with a standard starter battery.

Before you buy: check 3 key points

Although the batteries shown are sourced from information provided by manufacturers, we recommend checking on your current battery:

Dimensions (length × width × height, including terminals and protrusions)
The dimensions shown are the maximum of the battery and include the height of the terminals, small ridges at the base and any lateral protrusions. Measure your current battery completely, from edge to edge. The new one must be the same size or slightly smaller — never larger, it would not fit in the housing.
Positive terminal (left or right viewed from the front — check the battery photo carefully)
Stand facing the battery, with the manufacturer's label facing you and the terminals on top. Locate the terminal marked with +: if it is on your right, it is "positive right"; if it is on your left, it is "positive left". Do not rely on how the battery is mounted in the car — the position is always measured looking only at the battery itself.
Technology (AGM, EFB or conventional — Start-Stop requires AGM or EFB)
Depending on the manufacturer, the same technology may be labelled differently: AGM may also appear as VRLA, AGM Start-Stop or AGM Deep Cycle. EFB may appear as EF, EFB+ or Enhanced Flooded Battery. Conventional may appear as SLI, Lead-Acid, Wet or Standard. If your vehicle has Start-Stop, the battery must be AGM or EFB — never conventional.

If you have any questions, just ask us and we'll be glad to advise you with no obligation.

This is a standard or conventional battery for vehicles without a start-stop system

Does your car have Start-Stop?

Start-Stop switches the engine off at traffic lights. If your car has it, it needs an AGM or EFB battery.
