Nice. Yes, I can see where that would be super handy.

Nice device! The one I have has a large heating element inside and a needle voltmeter in the front, probably from the 80s.

[@RickCT2000]

That looks like a great product!

Still enjoying this product? Just picked one up, can't really find any negative reviews.

Yes still running strong. Used it last week on my tractor

@@LivingWithAClassic thanks for the info! Have only heard a few complaints about it so far, so I'm pretty confident i got a reliable tool.

There is only one true way to test a battery. Charge it fully then apply a known load and time it, monitoring voltage until it’s at 50% SoC
