Lead carbon batteries are better at sitting at partial states of charge (PSOC). Ordinary lead type batteries work best and last longer if they follow a strict ‘full charge’-‘full discharge’-full charge’ regime; they do not respond well to being charged at any state in between full and empty. Lead carbon batteries are happier to function in the more ambiguous charging regions.

Lead carbon batteries have longer a longer cycle-life. If you take the battery’s ‘end of life’ to be the point at which it can only be charged/discharged to 80% of its original capacity, a lead-carbon battery will last for 7000 cycles at 30% DoD daily – compared to 2000 – 5500 cycles at 30% DoD for VRLA-types and 800 cycles at 30% DoD for flooded batteries.
