Care tips for AGM batteries

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. A full charge now and then helps an AGM battery that mostly works part-charged.

Check before ordering

✓ Capacity is 28Ah. Aim for the same figure as your old battery or slightly above, never much lower.
✓ As a AGM battery it needs matching charge settings in the alternator, charger or solar regulator.
