Description
The US Battery US AGM 12V240 is a high-capacity 12V AGM battery rated at 230Ah in U.S. Battery's Group 921 case, built for equipment that needs a single large 12V battery instead of a series pack — think renewable energy storage, large cleaning equipment, and industrial applications with demanding runtime requirements.
Group 921 sits below the 4D and 8D cases in U.S. Battery's single-battery 12V lineup — enough capacity for serious equipment without the extra length of a 4D or the weight of an 8D. If 230Ah covers your runtime needs, this case is easier to handle and fit than the larger formats above it.
Why choose the US AGM 12V240
- 230Ah of deep-cycle capacity in a single 12V case
- Sits between standard Group sizes and the large-format 4D/8D cases
- DT-3/8 terminal for heavy-duty wiring connections
- Sealed, non-spillable AGM chemistry — zero maintenance, zero leak risk
