Q5: How do I confirm if my vehicle battery is bad or good?
A: The battery tester will display SOH (State of Health), SOC
(State of Charge), CCA (Cold Cranking Ampere), Voltage,
Internal Resistance, and Rating, with an intuitive test result of
"GOOD" or "BAD" for your reference. If the internal resistance
is too large, it indicates a broken battery.
Q6: Can this battery tester estimate the remaining
capacity of my battery?
A: Yes. The battery tester will display SOC (State of Charge)
to express as a percentage of your battery's rated capacity, a
measure of its condition to assess the potential energy.
Note that a decent SOC (State of Charge) doesn't mean
the battery is in good condition. You need to refer to your
battery's actual CCA Value and Internal Resistance for further
analysis.
