What type of battery does my caravan or motorhome need?

Caravans require two types of batteries: a starter battery (just like a car) and a service battery (for 12V appliances). The service battery must be a deep-cycle battery (AGM or GEL) to withstand repeated discharges.

Why can't I use a regular car battery in the caravan?

Standard batteries are not designed for deep discharge. If you discharge them below 50%, their lifespan is drastically reduced. Always use deep-cycle AGM or GEL batteries for your passenger compartment.

How do I find the right battery for my vehicle?

Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.

What warranty do the batteries have?

All our batteries come with the legal guarantee provided by consumer law against manufacturing defects. If a battery has a manufacturing defect, it will be replaced at no cost to the user.

How long does it take for the battery to arrive?

Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.

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 — the same as your current battery or higher)
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.

AGM / EFB batteries

AGM or EFB technology batteries: more charge cycles, faster recovery and a longer life than a conventional battery.
