Description
The Leoch LDC6-400-L16 is Leoch's largest 6V single-case AGM — 400Ah in the industrial L16 (BCI Group 903) footprint used for heavy-duty battery banks: large solar/off-grid arrays, industrial floor scrubbers and sweepers, and construction/utility equipment that needs to run a full shift without a swap.
Built with lead-calcium grids, copper-alloy terminals for high-rate discharge, and TTP-welded construction for low internal resistance. Rated for 1300 cycles at 50% depth of discharge, with high charge acceptance that gets it to 90% state of charge in about 3 hours — useful for solar setups with a limited daily charge window. UL recognized, IEC60896-21 & 22 certified, and IATA-approved for air freight.
Good fit for
- Large solar and off-grid battery banks
- Industrial scrubbers and sweepers
- Construction and utility equipment
- Telecom backup
