The Simplex SLA1097 is an aftermarket sealed lead-acid replacement battery for the Simplex 2081-9274 (also marked 112-133). Specifically, it provides 12 volts at 10 amp-hours of standby power for Simplex fire alarm control panels.
In addition, the SLA1097 matches the form factor of the OEM 2081-9274. As a result, it drops into existing battery compartments without bracket changes. Furthermore, it ships ready to install with the correct Faston terminal style for the original cabinet.
Why Replace with the Simplex SLA1097
First, fire alarm standby batteries degrade over time and lose usable capacity. As a result, NFPA 72 calls for a replacement cycle to keep panels within code. Therefore, scheduled replacement is part of a healthy life-safety maintenance program.
Furthermore, the SLA1097 uses AGM (Absorbent Glass Mat) construction. Also, the sealed design is maintenance-free, spill-proof, and rated for any mounting orientation. Therefore, it suits the closed cabinets used in fire alarm installations.

Compatible Simplex Panels
The Simplex 2081-9274 was originally specified for several Simplex addressable platforms. These include the 4100ES, 4100, 4100U, 4020, 4010, 4005, 4002, and 4001 panels. However, always confirm the existing battery’s dimensions and terminal style before ordering. In addition, check that your panel’s charger float voltage matches the SLA1097’s range.
Replacement Best Practices
- Replace in matched pairs of the same age and brand for series 24V configurations.
- Date-mark each new battery at install for the next replacement cycle.
- Verify standby and alarm load capacity after install per NFPA 72.
- Recycle removed batteries through a certified lead-acid recycler.
