The hydrometer is the 'official' check I guess, but it takes time and is messy - or I'm impatient and sloppy.....

Good question on that load tester, wondr if it's like mine - basically a big resistor that puts about 100 amp load on the batt with a meter that reads voltage. Never used it on deep cycle batts, just the hydrometer. and voltage check.wombat _______________________________________________ Elec-trak mailing list Elec-trak cosmos phy tufts edu https://cosmos.phy.tufts.edu/mailman/listinfo/elec-trak
