    Battery charging

    I have a 2017 Golf Estate Match 1.4 TSI DSG. Because of self isolation and lack of use over the last 4 weeks the display is telling me the battery is low.

    It will start and I run the engine a bit every week in the garage but I would like to put a battery charger on it.
    Can I put a trickle charge on the battery say 2 amps without disconnecting the battery and losing all the settings?

    Use a cTeck unit, very affordable. Put the earth to the body tag, not the battery terminal. When the world unlocks itself, I am expecting a huge demand for new batteries and jump start call outs... got one step ahead of the panic buyers for one by putting a new battery on Mrs Crashers Polo on Saturday as it was totally dead and would not take charge... three year old Exide Premium!

    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    I had the battery is low warning on my radio for along time before I brought a new battery, even though it starts up normal.

    There are plenty of trickle chargers on the market you can Google, mine only puts out 6A.

    How long should the battery be able to keep charge? My car managed one start after three weeks, and then would not start. I'm still not clear on how much of a drive is required to just recover the charge taken by starting the car, especially in light of all the magic boxes drawing current in a modern car.

    Hmm, well I started car, moved it, started it again and moved it back, next day put it on charger. Charger was showing battery was not in great state. Took it off charger this morning, car won't start, 10V odd only. Strange, seems like being on the trickle carger pushed it over the edge. Anyway, now I get to take car to dealers for battery testing and replacement...

    I have a CTEK and they sell Direct Connector Adapters which connect directly to the battery terminals. I leave this adapter connected permanently to the battery (one model also has an LED indicator state of charge) and just plug the charger lead into this adapter. Seems to work OK. CTEK make the same model of automatic battery charger for Jaguar, Aston Martin amongst others. They also offer a comfort indicator which is able to charge through the cigar lighter socket - just right for A-M owners!
