![]() You'd have to ask the manufacturer what's correct. There are certanly ways in which a heavier batter can have less capacity, usually due to incrasing some other quantity, but here the cranking amps are the same, and the two capacity specs conflict. "Reserve Capacity" is how long they can deliver 25A for at 80F if fully charged, while staying above 10.5 volts.įor the first battery, that's 210, which equals 87.5 AH (at the 3.5 hour rate) yet somehow the (presumably) 20 hour rate is only 65 AH.įor the second, it's 130 which equals 54.17 (at the just over 2 hour rate) and that, as expected, is less than the (presumably) 20 hour rate of 85. Positive Terminal Location Top Left Front that lets you reach deep into the battery racks to completely probe the terminals. Negative Terminal Location Top Right Front Streamline UPS and lead-acid battery diagnostics with measurement and. ![]() I was wondering if there was possibly a typo on their website or if a larger battery could indeed have less amp hours of power. APPLICATION - this multimeter can be used as battery voltage meter, battery capacity tester and temperature indicator panel for car, marine, RV, boat, etc. ![]() I wanted to use this battery as a backup for my 1/4hp sump pump and also for a 56 ft-lb electric trolling motor so I really value a higher amp hour over startup cranking amps. Note: The figures in the AGM battery voltage chart, lead acid battery voltage chart, and car battery voltage chart are based on open circuit readings. I got it home and looked online and found that the group 29 battery weighs 10 pounds more than the group 27 battery and the group 29 had 20 amp hours less power than the group 27. The battery voltage chart below shows the voltage and approximate state of charge for each type of battery, including AGM batteries, lead acid batteries, and car batteries. Learn the importance of measuring the state of charge of deep-cycle batteries by evaluating open circuit voltage and calculating specific gravity of deep-cyc. 1-48 of 219 results for 'deep cycle battery tester' Results Price and other details may vary based on product size and color. I just got a group 29 duralast marine deep cycle battery from auto zone. ![]()
