Hey. I would not recommend buying a cheap charger for your Audi. It wears out very quickly.

it be fine to use now mostly at least to get it to a state of charge to start the car! ---just not an optimum charge curve and may not get battery past 90% / or a bit over charge etc as it may be slightly confused logic when to cut out at its U vs A

my old off grid shed solar panel with charge controller ( that has different battery type settings) to suit pb and leisure batteries trickle charges batteries into life well just like the charge controller on a camper

on a side note the silver calcium batteries fitted to fords are rubbish at accepting a normal charge and have the smart charge system built in etc i replaced my new transit van battery with a stop start battery

CTEK MXS 5.0 has got to be the only one to go for IMHO

As recommended by BMW, Audi, Porsche etc
These are the ones you will find in all the showrooms

I use CTEK - which is Audi’s recommended charger. I have the CTEK MXS 10 which can be left connected long term to trickle charge and condition the battery.

I’m often away for 6 months at a time (Pre-Covid) and always hooked it up, and came back to a fresh battery every time

CTEK are good but the MXS series still do the 15.7 voltage desulphation pulse at the start of charging, regardless of charging mode. AGM batteries really don’t like that.

The ‘Time To Go’ series don’t have this.
