Review: Great handy device - Had a flat battery in November 2022 due to the -8c weather, got the car jump started, taken it for battery test at local garage, they couldn't tell if the battery was recovering or not so failed the test but told me to drive the car to see if it would charge up and re-test it, I took it back to the garage they are saying it no longer shows as failed but charge and re-test,, it's getting tricky to determine if the battery is recovering especially with the winter we are having and the cold snaps and it being xmas and the car sitting on the drive. so I saw this item, which is fantastic, so small, clear display and it is showing the problem I have with the battery and that by driving about I am getting some improvements in charge and i'm able to track those improvements. Before I did this video, Car switched off , shows 11.7v, |I drove about 11 miles to Asda, tested it and it was 11.9v, went round the shop for 1 hour and half, retested in the car park before switching on the car, video is shot in rugby Asda car park. Got home, 12.1v, with engine switched off, so there is hope if I take it for another few spins. A new car AGM battery for Skoda Octavia 2017 models costs a whopping £358! so I'm doing all the testing I can to see if I can avoid replacing a battery which is just over 5 years old. What I like about this device it shows you clearly in digital form the voltage, and if you have the engine on you can see if your alternator is working as it should show this from 13v to 14.8v. Such an inexpensive useful item, don't need to get the hood open and a meter plugged in or use one of those devices that just shows lights, this is showing me exactly what I need to know. I have a blackvue magic pro / dashcam in the car which is designed to keep the cam powered when the engine is off until the voltage drops below and certain level and I can verify this is all happening while watching the this unit's display. Must buy for anycar!, answers questions like does my cigarette lighter stayed powered when the car is off, answer for mine is yes it does, so don't leave it plugged in when the engine is off and forget about it!.
Review: Nice and simple idea - Well made and simple just keep in y the cigarette lighter (if it is only live when engine running) and you will see when the battery needs charging
