I always had an itch to get the battery tested – if I got a lemon fitted.
BHPian SilverSmoke recently shared this with other enthusiasts.
Decided to test the battery – ordered a tester online & got to work.
During the incident year back, battery was replaced (as a good gesture by Brite Skoda) with theoritical new battery – as older one got dead standing idle for 90 days in workshop. Hence, I always had an itch to get it tested – if I got a lemon fitted.
One can’t afford to do that when 90% of car is electronically dependent & controlled.
In this tester, there are three parts / phases.
After attaching the electrodes to respective terminals, it draws power & get started up.
In phase 1, battery morphology type is selected – in this it’s AGM.
Phase – 2 – Battery subtype is selected – SAE for our Varta.
In 3rd Phase, value for EDC (Estimated Discharge Current) is fed – it’s 680 Amperes for this battery. Enter the value mentioned on battery. Don’t confuse with DIN Amperes – it’s also mentioned & it’s different.
Last phae 4 is actual testing phase.
SOH – State of Health came 97%. Which is pretty good – depicting new battery was placed in.
Anything below 55% needs immediate replacement.
I.R. – Internal Resistance is 3.7 Mili Ohms – anything below 5 mO is nice.
Ideally it should be zero – meaning current is flowing with almost no resistance within the battery.
SOC – State of charge is 77% – good again but little below my expectations – it should be above 80% in regularly used car.
Volts are 12.5 – pretty much normal.
Actual Discharge Current – Cold Cranking Current is 663 Amperes
Hence, deducted the fact – this battery will keep serving for 2 more years atleast if maintained properly.
