What is a GEL battery?

GEL is a sealed lead-acid battery where the electrolyte is in gel form (not liquid or absorbed). It tolerates deep discharges very well and is ideal for cyclic use (solar, caravans, electric wheelchairs). Far more tolerant of deep discharges than conventional batteries.

When should I choose GEL over AGM?

Choose GEL when usage is mostly cyclic (repeated deep discharges) and ambient temperature is moderate. AGM handles extreme cold and high-current cranking better. GEL handles deep discharges better and lasts longer in caravans with steady consumption but infrequent cranking.

How long does a GEL battery last?

Between 6 and 10 years under normal conditions — longer than most technologies. Real-world life depends heavily on the charging regime (it needs a GEL-specific charger — the curve differs from AGM or conventional) and ambient temperature.

Can I charge a GEL with any charger?

No. GEL requires a charger with a specific GEL profile (max charge voltage ~14.1 V vs 14.4-14.7 V for AGM). Charging it with an AGM or conventional profile drastically shortens lifespan. Any modern smart charger (CTEK, NOCO, Optimate) has a GEL mode — always select it.

Does GEL handle the cold?

Yes, but not as well as AGM. For starts in caravans in very cold climates (-10°C or below), AGM has better cranking performance (higher CCA). For cyclic use (energy, deep discharges), GEL is the best option even in cold conditions.

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 engine comes with an AGM/EFB battery as standard: the car's charging system requires it even without Start-Stop. If in doubt, message us and we will confirm.
