🔋 ALLOSUN GK503 12V Automotive Battery Tester: Charger, Alternator & Cranking Check - Multi Function Car Battery Diagnosis Handy Tool, Blue Review

In order to test my car's battery and make sure it's safe to drive, I decided to buy a daily tester instead of a professional one. I searched on Revain and found this. As said, this item is really suitable for light daily use. It is so portable that you can hold it conveniently and take it with you wherever you go.

Works once, then only lights up next to "Crank Check" mode instead of showing the battery percentage. The battery isn't in the car so I don't know why it shows that (like the first time so nothing has changed). My charger shows full charge. I have used it several times exactly as directed. Cannot be returned, wasted money.

Excellent just what you need when looking for problems with electricity I thought I had a bad battery but after replacing the battery it died anyway so I thought the Allorator but with this tool does it It showed me that it was good. My 10 year old son discovered the problem when he told me my brake lights were on as he walked in the driveway so I check and am sure the brake lights are on. I thought it was the brake switch but not even that. The brake pedal has a hole where the switch is…
