This is the one I bought. I was attracted to the radial fins, they reminded me of a WWII fighter aircraft engine. 150W 200V 20A Constant Current Electronic Load Battery Discharge Capacity Tester 830479667608 | eBay
Is this cutoff setpoint the same for Gel Cells, or should it be something different? Paging Mainesail...You can set the "Shut Off" Voltage where you want the test to stop (10.5 per Mainesail's instructions).
How is that, Benny. Please explain.Nifty tester but testing one battery at a time can be time consuming and testing just the whole bank can yield inaccurate results.
What does that mean, Benny, a "comparative state of health," and how do you determine that with "a simple automotive voltage and load tester?" And what's the point?Suggest using first a simple automotive voltage and load tester to determine that all batteries in a bank will be in a comparative state of health before conducting the Capacity Test.
An automotive battery tester is useful for checking starting batteries, but no so useful for checking the capacity of your house bank. The automotive tester can put up to a 500 amp draw on your battery for a few seconds, much like what happens when you start the engine. This information is not very relevant in determining how much capacity your house bank may have lost. Whereas the testers that we are looking at drawdown at a max of 13 amps (150 watts or can be set for less). This is more inline with how we use house banks.Nifty tester but testing one battery at a time can be time consuming and testing just the whole bank can yield inaccurate results.

The cut off for all lead acid batteries is 10.5V (under load) per BCI 20 hour testing standards. If the tester does not have a dedicated volt sense lead then you'll need to figure in the actual voltage drop at the 20 hour load for the pos & neg wires.Is this cutoff setpoint the same for Gel Cells, or should it be something different?
