Battery load tester?

I wonder if anyone has used, or has an opinion on (hah!) this "battery analyzer", which apparently determines the internal resistance of the battery to gauge its capacity and health.

I had a deflated battery that couldn't catch it's breath but a good swift kick in the butt cured THAT

Never had a depleted bad battery test good on load test
you put a proper test using the specs for that battery's rated capacity
it will NOT test good if it can't carry the amps for the full TIME DURATION
a battery with an internal leakage, can carry full amps when tested at full charge, but still loose charge from the leakage
load capacity is just ONE test
holding voltage at rest is another test
as is reading the SG of Flooded cells

i have the Harbor Freight 500amp carbon pile tester
also available online under other brand names, same tester

it has been very useful, i'm happy with it

Wow, after 50 yrs of testing batteries, I learned something new:R

Last time I saw them, they were 20 bucks at Harbor freight. They are cheap but they work. Some cold hearted theif stole mine, so I replaced it w/ their $50 500 amp carbon pile tester.

Look on amazon tons of them just depends don't buy a cheap one you get what you pay for.

You can always just take the batts to auto parts store they can do for free
