## Description

More than 300 **boat batteries** from Exide Marine, Varta Professional, Fullriver, Optima Blue Top and Trojan: starting, cabin service and dual purpose, in conventional, EFB, AGM, GEL and lithium, 50 to 240 Ah.
For service use, work out your daily consumption in Ah and pick a capacity that stays below 50% depth of discharge. **Shipping in 24-48 h** to the marina or your home; batteries over 30 kg travel by freight.

## How to choose the right marine battery

The most expensive mistake in marine use is fitting a starter battery for service duty: the thin plates of an SLI cannot tolerate deep discharge and sulphate within 4-6 weeks of anchoring. The opposite is just as costly: using a service battery (thick plates) to crank an outboard — it doesn't deliver enough CCA and the starter motor doesn't get the peak it needs in cold water. **Each role demands its own battery.**
