Using it day to day: practical tips

An alarm panel beeping at three in the morning usually means its battery is low. Recycle old batteries through an authorised scheme. Batteries that look perfect from outside can still fail under load.

AGM: how it works

Valve-regulated construction keeps an AGM case closed during normal life. Backup systems rely on AGM because it can wait, fully charged, for years without fuss. Replace an AGM battery whose case has bulged.

Will the Long MSK440 fit?

• ✓ Check 197 × 170 × 342.5 mm against the tray, not just the old battery.
