Simplex 2081-9274 — 12 V sealed lead-acid system battery rated 10 Ah at the 20-hour discharge rate.
Simplex panels take their secondary supply from two 12 V batteries wired in series for 24 V. At 10 Ah this is one of the four smaller sizes that fit the included cabinet on every Simplex panel series rather than needing an external enclosure. Lead-calcium grids and immobilized electrolyte give rated capacity on the first cycle.

- 6 in. W × 4.06 in. D × 4 in. high over terminals; 9.2 lb (4.2 kg)
- Dual-seal polystyrene cell cover; UL 924 recognized pressure relief valves

Neighbouring rows are 2081-9286 at 7.0 Ah and 2081-9288 at 12.7 Ah, and 2081-9275 at 18 Ah, which fits the panel cabinet on five of the nine series listed and needs an external cabinet on the rest.
