does anyone have one of these ? I am guessing not as you all seem to have a lot more money than me . . . Any good or just trash ?

I paid £5.99 to see if I could determine my battery was on the way out , I am assuming it is because the 'Full' battery dropped to 'Low' within minutes before my very eyes, seems to start the car okay at present, . . . . going to charge it a bit over night and check tomorrow if the charge falls again.

Confess, yes I do. Had it for years, for the caravan battery and check the charging in the caravan locker.

Did you understand it ? I assume the green OK light means battery is alright, but if fully charged you wouldnt expect a drop from full to low within 5 minutes ? 2017 SEAT Ateca 4drive 2.0 xcellence (May 2022 -
