Review on 🔋 LEICESTERCN Battery Tester: Ultimate Digital 12V Car Battery Load Test and Analyzer - Flood, Gel, AGM, Deep Cycle Battery Examinations by Lancy Rakesh

I bought this to test out a few batteries. of different ages (from two months to 5 years). Some that I knew needed "minor" [or beyond] replacement. EVERY battery is "100% good" tested. I followed the instructions carefully and tested the batteries in various "states" (ranging from 35 minutes to several tens of hours disconnected - and I used a Schumacher charger to find that the batteries were draining a bit and not 100% were loaded). Regardless of condition or condition, all batteries - and the same batteries - have been tested for "100% good quality". And yes, I checked everyone's CCA rating and set the analyzer to that number (the only variable you can control/set) - and according to that analyzer, all the results were the same. Maybe it's my personal analyzer, but there's no way every battery is literally perfect. I returned mine and will buy a more expensive analyzer in the hope of getting more logical results.
