Measurements, ratings and codes

Fitting and everyday care

Commuter scooters do short hops every day and rarely give the battery a full charge. A quick-connect lead left on the battery makes winter top-ups easy. Storing a bike for winter without a maintainer often ends with a new battery.

How AGM batteries work and how to look after them

Glass-fibre separators in an AGM battery act like blotting paper for the acid. Premium cars with lots of electronics usually come with AGM from new. Keep AGM terminals clean and tight.
