Direct 12 V 1.2 Ah SLA replacement

This sealed lead-acid battery fits UPS units that specify a 12 V 1.2 Ah pack. It matches the bp1.2-12, wka12-1.3f and wp1.2-12 part numbers for a 100 % OEM-compatible swap. Home-office users and small-server operators can install it without tools or configuration.

AGM chemistry runs maintenance-free

Absorbent Glass Mat construction keeps the electrolyte immobilised so the cell never needs watering or venting. The 1.05 lb unit delivers its rated capacity with low self-discharge during normal float service. Typical float life spans four to seven years under standard ambient conditions.

Two-year warranty backs the PowerStar brand

BatteryJack inc. supplies the cell under its PowerStar label with a two-year limited warranty on the battery itself. No cables, mounting hardware or monitoring software are included in the package. Buyers who need extended runtime or higher-capacity packs should select a larger Ah model.

Questions about this item

How do I install the 12 V 1.2 Ah SLA battery and which step is often missed?

Disconnect the UPS from mains, open the battery compartment, remove the old pack noting the red-to-positive and black-to-negative leads, insert the new 3.82 × 1.69 × 2.19 in unit, reconnect the leads in the same order, then close the cover and power on.

What maintenance or replacement will the 1.2 Ah AGM cell need later?

The sealed AGM design is maintenance-free; no watering or terminal cleaning is required. Plan to replace the battery after the expected 4–7 year service life or when runtime drops below acceptable levels.

What limit appears first on the 12 V 1.3 Ah pack during sustained discharge?

The 1.2 Ah capacity rating sets the runtime ceiling; under continuous load the voltage will fall to the UPS cut-off threshold once the stored ampere-hours are depleted.
