AGM Super Cycle 12V/38Ah (M5) - AGM battery for frequent deep discharges
AGM Super Cycle 12V/38Ah (M5) is an AGM battery designed for applications with frequent deep discharges. Improved electrochemistry makes it resistant to sulfation and plate softening even after repeated 100% discharges, with tests showing at least 300 full cycles. With 38 Ah it suits small mobile systems, small boats and off-grid applications.
Main features:
- Voltage and capacity: 12 V, 38 Ah (C20)
- Cycles at 100% DoD: 300 cycles
- Partial discharge cycles: 700 at 60% DoD, 1,000 at 40% DoD
- Recommended use: occasional 100% or frequent 60-80% DoD discharges
- Terminals: M5 threaded inserts
- Dimensions and weight: 267 × 77 × 175 mm, 9.5 kg
The Victron AGM Super Cycle Battery is designed for applications that involve frequent deep discharges.
Thanks to improvements in battery electrochemistry, it resists sulfation and plate softening, even after repeated 100% depth of discharge (DoD) cycles.
Tests have shown that Super Cycle batteries can withstand at least 300 full 100% DoD cycles. This makes them a reliable choice for mobile, off-grid and marine applications where occasional full discharges or frequent partial discharges are expected.
