Installation and maintenance tips

A storm knocks out the power and the UPS takes over in a heartbeat. Let the equipment charge new batteries fully before relying on them. Exit lights that fail their duration test often need new batteries.

Buying the Long WP9B-4 online

Home alarm systems and garage door motors also use the Long WP9B-4. Standby batteries are judged on voltage, capacity and terminal fit. Buying batteries online by exact reference avoids mixing makes in one UPS string.

8Ah puts it squarely in the middle of the range for UPS and standby systems.

Questions and answers

What if I do not know my battery reference?

Look for the printed code on the battery label, then search on baterias.online for the brand followed by that code, for example Long WP9B-4.

Is this battery easy to lift?

At 3.46 kg, it is manageable for one person with care. Keep it upright while moving it.

How should I store the Long WP9B-4 if I don't fit it immediately?

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

Five checks for a perfect fit

✓ As a AGM battery it needs matching charge settings in the alternator, charger or solar regulator.
✓ Dimensions to compare: 150 × 69 × 105 mm. Do not forget the base ledge, which the hold-down clamp grips on many vehicles.
✓ Do not go far below your old battery's capacity; this one has 8Ah.

What AGM means for you

Glass-mat batteries are sealed, with small valves that only open if pressure builds up. Glass-mat batteries recover well after a deep discharge compared with flooded ones. Old-fashioned chargers without automatic cut-off are a poor match for glass-mat batteries.
