12V 2.3AH SLA battery for UPS units

This 12V 2.3AH sealed lead-acid battery delivers 28W of power for uninterruptible power supply units. It uses AGM technology with a recombinant design that controls over 90% of gas generation. The sealed construction prevents electrolyte leakage in any mounting position. It arrives ready for maintenance-free operation.

Suits UPS units needing T1 terminal 12V 2.3AH cells

Buyers replacing a 12V 2.3AH SLA battery with T1 terminals in a UPS or backup device will find a direct 100% OEM fit. The four-to-seven-year expected service life supports long float deployments. Shoppers needing higher capacity, different terminal types, or lithium chemistry should look at other models.

Simple drop-in swap with T1 terminal access

Installation requires disconnecting the old cell and connecting the two T1 terminals to the existing leads; no tools beyond a screwdriver are typically needed. The sealed, non-spillable design meets IATA requirements for safe handling. The only common issue is reversed polarity during reconnection, so verify terminal markings before tightening.

Questions about this item

Does my UPS need 12 V 2.3 AH SLA chemistry with T1 terminals to accept this battery?

Yes, this unit is a 12 V 2.3 AH sealed lead-acid battery with T1 terminals, so the UPS must be designed for that exact voltage, capacity and terminal type.

Will the 28 W rating and AGM construction work in a UPS that originally used a standard flooded cell?

The 28 W AGM battery is maintenance-free, non-spillable and recombinates over 90 % of gas, making it a direct drop-in for older flooded designs that share the same 12 V 2.3 AH T1 specification.

How can I verify the battery is delivering its rated 28 W after installation?

Run a self-test or load test on the UPS; the unit should hold voltage under load for the expected runtime and show no electrolyte leakage, confirming the AGM cells are performing to the 28 W rating.
