What is the industry accepted guideline for determining an acceptable battery impedance value?
I tested a battery yesterday - it was a three year old Honda OE 51R battery.
The tester showed the charge to be 100% and the CCA was a bit above the 400 spec. Voltage was normal, and the testing was done about 1/2 hr after shutdown.
The impedance value was 6.90 mohm, which seems a bit high - and is what's concerning me.
Can anyone provide some guidance on this matter?
Thanks
