Practical advice for boats and motorhomes
A campervan on a rainy week in Scotland leans hard on its leisure battery. Protect every terminal with a boot or grease and use tinned cable lugs aboard. A motor mover that struggles may be a sign of a weak battery.
About the technology: AGM
Each AGM cell is packed so tightly that the plates barely move, even on a bumpy road. Glass-mat batteries recover well after a deep discharge compared with flooded ones. A full charge now and then helps an AGM battery that mostly works part-charged.
Quick compatibility checklist
- ✓ Some equipment needs adapters for M6 terminals.
- ✓ Technology to match: AGM. Moving to a different chemistry may need settings changed in your system.
- ✓ Check 229 × 138 × 212 mm against the tray, not just the old battery.
