Installation and maintenance tips

A scooter used only once a week can lose charge between trips. Check the battery box for loose connectors every few months. Batteries that need charging twice a day for normal use have reached the end.

What AGM means for you

Picture a sponge holding the acid: that is roughly how an AGM cell works. Premium cars with lots of electronics usually come with AGM from new. Charge an AGM battery on a programme made for AGM, not a generic setting.

Check before ordering

• ✓ Sticking with AGM avoids surprises, unless your vehicle maker approves a change.
• ✓ Will it fit? The MK Battery 8A4D measures 537.2 × 213.6 × 249.7 mm, so compare length first, then width, then height with the lid or bonnet closed.
• ✓ With 198Ah of capacity, hold it up to the figure on the outgoing unit or in your equipment manual.
