Fitting and everyday care

Hilly routes and soft tyres drain mobility batteries faster than flat pavements. Use the charger supplied with the chair or one set for the AGM chemistry. Range that halves within weeks usually means worn batteries.

The AGM technology explained

Many glass-mat designs tolerate sideways mounting, as long as the maker says so. Motorcycles benefit from glass-mat batteries because they tolerate lean angles and vibration. Over winter, a smart unit set to its AGM programme keeps a glass-mat battery healthy with no effort.

Will the MK Battery ES3-12 fit?

  • ✓ Check that the alternator or controller suits AGM.
  • ✓ Dimensions to compare: 134.1 × 67.1 × 65.5 mm. Do not forget the base ledge, which the hold-down clamp grips on many vehicles.
  • ✓ Rated 3Ah: check that the charger or alternator in your system can refill a battery of that capacity in reasonable time.
