The Simplex SLA-1154 is an aftermarket sealed lead-acid replacement battery for the Simplex 2081-9271 (also marked 112-047). Specifically, it provides 12 volts at 33 amp-hours of standby power for Simplex fire alarm control panels and notification appliance power supplies.
In addition, the SLA-1154 fits the same footprint as the OEM 2081-9271. As a result, it drops into existing battery cabinets without bracket modifications. Please note: this item ships in a minimum order quantity of two batteries, since most Simplex 24V systems use a series pair.
Why Replace with the Simplex SLA-1154
First, fire alarm batteries have a finite service life. NFPA 72 generally calls for replacement on a defined schedule. Therefore, regular planned replacement keeps the system within code.
Furthermore, the SLA-1154 uses sealed AGM (Absorbent Glass Mat) construction. As a result, it is maintenance-free, spill-proof, and rated for any mounting orientation. Also, the AGM design tolerates the typical float-charge regime used by Simplex panel chargers.

Compatible Simplex Systems
The SLA-1154 supports Simplex fire alarm panels and remote power supplies that originally specified the 2081-9271. However, always confirm the existing battery’s physical dimensions and terminal type before ordering. In addition, verify that your panel’s charger float voltage falls within the AGM range.
Replacement Best Practices
- Always replace batteries in matched pairs of the same age and brand.
- Date-mark each new battery at install for the next replacement cycle.
- Run a 24-hour standby and 5-minute alarm load test after install (per NFPA 72).
- Properly recycle the old batteries at a certified lead-acid recycler.
