HF Battery testers
I have a bunch of car/truck batteries sitting around in my shop and I want to test them so I can recycle the bad ones and use the good ones for a rare non-electric-hookup 3 day campout with our TT. ...

Find the CCA of the battery
The LOAD you apply will be one half that.
Test only a fully charged battery
Use a clock or a watch
Load battery for 15 seconds
It must not sag the voltage below nine point six volts
Hold amperage steady meaning twist the dial more if necessary
If amperage then voltage sags on its butt the battery is unrecoverable
If voltage slowly sags below 9.6 volts check cells with a hydrometer
Test Golf car batteries in 12 volt 6 cell series
Load to 200 amps for THIRTY SECONDS. Must remain above 9.6 volts.
Results from a Carbon Pile test trumps anything gotten from an impedance teste but not the other way round.
