Someone ran the numbers in an off-grid solar article and it was cheaper to hit golf cart batteries hard – 70% discharge or more – and replace them more often vs. doing the 50% routine and paying a lot for “trapped lead”. Joe Coquina

We used to figure 350 to 400 discharges into the 60-80% range. At least one of the battery manufacturers was starting to change the life expectancy & warranty to a function of AH used (modern commercial smart chargers can keep track of that sort of thing if properly set up). Service life for a 3000 AH forklift battery would be something like 450,000 AH with proper charging (8 hours use, 8 hours to charge, 8 hours to cool) and proper watering. That’s 300 cycles to 50% discharge. Rick Brass Washington, NC
