In pics: Testing the battery of my Skoda Kodiaq using a battery tester

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.
