Simplex 2081-9271 — 12 V, 33 Ah sealed lead-acid system battery in the rectangular case, rated at the 20-hour discharge rate.
Simplex lists two 33 Ah batteries. This rectangular-case 2081-9271 is marked in its data sheet as typically for service. The square-case 2081-9276 is the one Simplex specifies for new installations. Two in series give 24 V; Simplex requires the pair to match in voltage, model number and appearance and to have about the same date of manufacture.
- 12 V nominal; 33 Ah at the 20-hour rate

- Approximate weight 26.6 lb (12.1 kg)
- Mounts inside 4100ES/4100U and 4010ES cabinets
- External cabinet required with 4003EC, 4007ES/4005 and 4100/4120 panels

Case shape matters when choosing between the two 33 Ah parts. A 4100 or 4120 cabinet takes the square 2081-9276 inside but needs an external cabinet for this rectangular one. Neighbouring capacities are the 2081-9287 (25 Ah) and 2081-9296 (50 Ah).
