Installation and maintenance tips

Data centres replace whole strings of batteries on a schedule. Run a self-test after the fresh blocks have charged. Batteries that look perfect from outside can still fail under load.

How AGM batteries work and how to look after them

Nothing sloshes around in a glass-mat battery, because every drop of acid is held in the separators. Glass-mat batteries recover well after a deep discharge compared with flooded ones. Replace an AGM battery whose case has bulged.

Five checks for a perfect fit

• ✓ Capacity 0.8Ah: equal to or a little above your old label is ideal.
• ✓ It comes with JST terminals, so check that your leads, lugs or plugs can attach to them without adapters.
• ✓ Sticking with AGM avoids surprises, unless your vehicle maker approves a change.
