Using it day to day: practical tips

Hospitals rely on standby batteries for critical equipment. Disconnect the load before working on a UPS without hot-swap. Forgetting to note installation dates leads to batteries left in service far too long.

AGM: how it works

Oxygen formed at one plate travels through the mat and recombines at the other. Glass-mat batteries recover well after a deep discharge compared with flooded ones. A battery tester gives a clearer picture of AGM health than a voltmeter.

Make sure it fits your vehicle or equipment

✓ Rated 4.5Ah: check that the charger or alternator in your system can refill a battery of that capacity in reasonable time.
✓ It comes with F1 terminals, so check that your leads, lugs or plugs can attach to them without adapters.
✓ The technology is AGM. Keep the same type as the original, and confirm your charger offers a matching profile.
