Fitting and everyday care

A robot mower working every day in summer gives its pack plenty of cycles. Check the earth connection to the frame, a common culprit on garden machines. Robot mower packs that run out after a few minutes have reached the end.

AGM: how it works

Gas produced during charging recombines inside an AGM battery, so it loses almost no water. Glass-mat batteries shrug off vibration, which is why bikes and boats use them so often. Do not mix AGM and flooded batteries in one bank.

Questions buyers ask about the Fulbat SLA12-20

How much weight should I expect to lift?

The weight is 5.3 kg. Heavier batteries generally contain more lead and active material.

Does this battery start well in winter?

With 180A, it suits vehicles whose maker specifies that value or less. Cold climates benefit from extra.

Will the Fulbat SLA12-20 fit my tray and connect properly?

A physical match means the same case (182 × 77 × 168 mm) and the same terminal side (positive on the right-hand side).

Any tips for keeping a spare battery?

Yes, but all batteries self-discharge slowly. Check the voltage every few months and recharge if needed.
