## Frequently asked questions about the Motobatt MBTX7U

### Motobatt MBTX7U or MB5U?

### How much does the Motobatt MBTX7U weigh?

### 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.

## Inside the MBTX7U: AGM technology

The MBTX7U 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.
