BatteryJack inc. WKA12-2.3F 12V 2.3Ah UPS Replacement Battery

SKU CH-YFVJ-TGEYY

A 12 V 2.3 Ah sealed lead-acid battery designed as a 100 % OEM replacement for UPS and security systems

  • Maintenance-free operation thanks to sealed AGM construction
  • Direct 100% OEM replacement for GT011T5 systems
  • Long service life rated at 4 to 7 years
  • Reliable 12V 2.3Ah capacity for backup power
  • Three-year coverage on UPS and backup devices

Direct Replacement Battery

The PowerStar 12V 2.3Ah unit is a valve regulated sealed lead acid battery built as a 100% OEM replacement for the GT011T5 National Power Light or Security system. It uses advanced AGM technology to deliver maintenance free operation in a rugged, economical package. The battery arrives new and ready to install without additional preparation.

Thermals Noise and Power

Sealed AGM construction means the battery runs silently and generates no measurable heat during normal float charging or standby discharge. There are no moving parts, fans or pumps to create noise, and the unit draws zero power when not supplying the load. Expected service life spans four to seven years under typical UPS cycling conditions.

Upgrade Path and Value

This battery replaces an exhausted 12V 2.3Ah SLA cell in compatible security panels, emergency lighting or small UPS units, restoring full runtime without changing enclosures or wiring. The jump is worth it when the original cell no longer holds charge or when preventive swap is scheduled before the four year mark. Buyers needing higher capacity or a different voltage must select another model.

Questions about this item

How do I install this 12V 2.3Ah AGM battery and which terminal step is often missed?

Insert the battery into the UPS tray, connect the red lead to the positive terminal first, then the black lead to negative; the step often missed is tightening both terminal bolts to prevent resistance buildup.

What maintenance or replacement will this sealed lead-acid battery need during its 4-7 year design life?

The AGM construction is maintenance-free — no water topping is required — so the only action is a full replacement once capacity drops below usable levels, typically after 4-7 years.

What limit appears first when this 12V 2.3Ah unit runs under sustained load?

The 2.3 ampere-hour capacity is the limiting factor; under continuous discharge the voltage will fall to the UPS cut-off point once the stored 2.3Ah is exhausted.
