Technical figures at a glance
Fitting and everyday care
Long-weekend sailors often run the fridge and nav lights all night. Set the mains charger, the solar regulator and any B2B charger to the AGM profile. Lights that fade by midnight are a sign the domestic bank has lost capacity.
AGM: how it works
Tightly packed plates and mats give glass-mat batteries a sturdy inner structure. Wheelchairs and scooters often use AGM for clean, sealed power. A battery tester gives a clearer picture of AGM health than a voltmeter.
Five checks for a perfect fit
- ✓ Starting current 605A: look for the EN value on your old label and choose this reference only if it is equal or higher.
- ✓ Terminal check: M8. Spade widths and post diameters vary, so match the type exactly.
- ✓ The technology is AGM. Keep the same type as the original, and confirm your charger offers a matching profile.
