Installation and maintenance tips

A small shop's UPS keeps the till running through brief cuts. Keep spare batteries charged if they are stored for a while. A UPS that reports a failed battery test needs new batteries soon.

AGM: how it works

Gas produced during charging recombines inside an AGM battery, so it loses almost no water. Premium cars with lots of electronics usually come with AGM from new. Do not mix AGM and flooded batteries in one bank.

Five checks for a perfect fit

✓ Capacity is 2Ah. Aim for the same figure as your old battery or slightly above, never much lower.
✓ Check that the alternator or controller suits AGM.
✓ Check 150 × 20 × 90 mm against the tray, not just the old battery.
