Exide EN850: what it is and who it suits
If the logbook says Exide EN850, here are the numbers for the replacement. Weighing 25.4 kg, it needs a firm footing in the locker. Comparing capacity and weight on screen beats guessing in a chandlery.
Most batteries for boats and motorhomes land close to 110Ah, and this one does too.
Measurements, ratings and codes
Fitting and everyday care
Salt air on a mooring corrodes battery terminals faster than anywhere inland. Strap the battery down as firmly as you would the engine. Old and new batteries side by side make a weak team.
What lead-acid means for you
A classic lead-acid battery has lead plates sitting in liquid sulphuric acid. A wet-cell battery copes well with high engine-bay temperatures. Check the electrolyte level a few times a year if the battery has removable caps.
Check before ordering
- ✓ Cold cranking 750A: compare with your handbook's requirement.
- ✓ This reference uses lead-acid. If your current battery has a different technology printed on it, find out why before switching.
- ✓ Will it fit? The Exide EN850 measures 349 × 175 × 235 mm, so compare length first, then width, then height with the lid or bonnet closed.
