Fitting and everyday care
School-run traffic is a tough test for any eco-stop battery. Check whether the battery sits in the boot and needs a vent tube. Repeated deep drains from accessories left on age a stop-start battery fast.
Care tips for AGM batteries
Each AGM cell is packed so tightly that the plates barely move, even on a bumpy road. Wheelchairs and scooters often use AGM for clean, sealed power. A full charge now and then helps an AGM battery that mostly works part-charged.
Will the Fulmen FK508 fit?
- ✓ Diesels and big engines need the full 800A or more.
- ✓ The technology is AGM. Keep the same type as the original, and confirm your charger offers a matching profile.
- ✓ Grab a tape measure: 260 × 173 × 206 mm is what this case needs.
