Description
The negative plate is reinforced with carbon (Lead Carbon), which reduces sulphation when operating in a partially charged state, usual for a solar power plant on cloudy days. The AGM VRLA design is sealed and needs no water top-up. Service life is at least 12 years for 12 V units and at least 15 years for 2 V cells. There is a front-terminal version LRCF with terminals on the front panel, convenient for dense mounting in racks and cabinets. The case is ABS UL94-HB, UL94-V0 optional. Such batteries are charged from a hybrid inverter with the profile for lead-acid AGM, observing the currents recommended by the manufacturer.
How to choose
Large solar plant storage is better built from 2 V cells, which give 4000 cycles and 15 years against 3200 cycles and 12 years for units. 12 V monoblocks of 80–200 Ah suit small autonomous systems, and front-terminal LRCF suit cabinets. If an even longer life is needed, compare with LFeLi 12.8 V LiFePO4 batteries, which have 5000 cycles but at 50% DoD, so a direct comparison with figures for 60% is not valid.

FAQ
How many cycles does an LRC lead-carbon battery withstand?
At least 4000 cycles for 2 V cells and at least 3200 cycles for 12 V monoblocks at a depth of discharge of 60% DoD.
How does Lead Carbon differ from an ordinary AGM battery?
Carbon in the negative plate slows sulphation at partial charge. That is why LRC tolerate daily cycling in solar systems better.
What is LRCF?
It is the front-terminal version of the LRC series with terminals on the front panel, for mounting in racks and cabinets.
What is the service life of LRC batteries?
At least 12 years for 12 V units and at least 15 years for 2 V cells.
What capacities are available in the LRC series?
2 V cells are made in 600–1000 Ah, and 12 V monoblocks in 80–200 Ah.
