So my pickup truck was showing signs of a battery going bad I purchased a battery tester,
TOPDON AB101 Car Battery Tester 12V Car Battery Load Tester from Amazon and then tested the ‘15 Camaro out of curiosity (and just playing with the new tool) which was showing no signs of a battery issue and it runs the tests says to replace showing all the vital signs which aren’t good so I’m still skeptical thinking this 7 year old car has had to have the battery replaced (I’m the 2nd owner)
I check the battery date code and it shows 14/8/15 aka August 14, 2015 so 7 years 4 months and still starts amazing.

So it’s away for the winter on the Battery Tender and I’ll replace the Batt in the spring hoping the price drops a couple $$.
