Can this product be used on a deep charge golf-cart battery?

It can only be used to detect the car battery, not to charge the battery. Our BM550 battery tester can test all 6v 12v 24v 100-2000 CCA car batteries.

Will this tester accurately measure internal resistance in a 12V deep cycle lawnmower battery?

It measures 6v 12v and 24v system batteries. It does read internal resistance but I’m not sure how accurate that particular measurement is because I have never compared this other battery testers.

How do i know if my car battery test result soh, soc, and cca numbers are good or not?

Not sure about social or soh. Cca is one of two prompted questions. If you are not sure of target cca, you might need to look up you battery model and confirm. Once you input cca, the meter goes through a test cycle and gives you actual cca. It decides good or bad based on the cca you input.

Will it give the remaining ah amp hours for batteries or just cca?

Reported values are CCA's. Remaining AH isn't part of the output. You could, roughly, determine the remaining AH through the SOC (State of Charge). For sake of example, if the battery is a 10AH battery, and the SOC = 80%, then you have, roughly, 8AH "left" in the battery. That's not exactly the best way to derive that but it's a ballpark. The element that isn't taken into account is why the battery SOC is where it's at (e.g. age, degradation, discharge due to parasitic draw, etc.). Depending on the combination of those factors will determine what the actual AH capacity is, at that SOH and SOC.

Mai più sorprese per le non partenze dell'automobile

Lo strumento è molto utile per non farsi cogliere impreparati quando la batteria non ha più le prestazioni dall'acquisto. Occorre verificare lo stato della batteria ogni sei mesi.
