Agreed. My experience as well.Guys, don't get fussy over which brand of electricity you're going to charge your car with. Any charger is capable.
I have the ctek 5 amp item and the aldi. Personally I think the Aldi is just as good as the Ctek.
The Ctek being a bit more 'intelligent' does 'give up' on batteries that are failing whereas the Aldi one will recover ones that have been deeply discharged to a usable state.
