Optima YTS-4.2 for boats and motorhomes
Built for life on board boats and motorhomes, the Optima YTS-4.2 keeps lights and pumps going. With the positive on the left-hand side, the main leads should land where the old ones did. The code from the old battery is all the search box needs.
Among batteries for boats and motorhomes, 55Ah is at the smaller end. Big diesels and cold climates appreciate the 765A on offer here.

Fitting and everyday care
A yacht on a mooring all winter needs its batteries checked before launch. Strap the battery down as firmly as you would the engine. Old and new batteries side by side make a weak team.
How spiral-cell AGM batteries work and how to look after them
The unusual shape is the giveaway of a spiral-cell battery. Spiral batteries power winches and lights well. Deeply drained spiral cells may need a recovery function to wake up.
Make sure it fits your vehicle or equipment
- ✓ Check the EN figure on your old label against 765A.
- ✓ Check that the alternator or controller suits spiral-cell AGM.
- ✓ Check 254 × 175 × 200 mm against the tray, not just the old battery.
