### How do I stop the motorcycle battery going flat in winter?

Connect it to a maintenance charger or disconnect it if the bike will sit for more than a month. A flat motorcycle battery sulphates in a few weeks.

## AGM technology in the MB10U

The MB10U is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.
