Charging the battery

Post by Troc2018 » Mon Apr 20, 2020 10:48 am

my car as sat on our drive for a couple of months now, so although it starts ok and doesent seem the battery is going flat I thought I'd give it a charge up
Looked in the manual and couldn't see how to charge battery in the index , so I looked through and found on page 261 that you must not charge the battery yourself it has to be charged in a vw garage because it needs voltage - limited charging whatever that is , never heard of this before I've always charged battery's myself even with them in the car still and never had a problem

Just use a C Tek trickle charger, it's what most VW dealers use on their showroom cars after all, I think the issue is the car doesnt charge itself fully when driving to allow for the battery regen to have space to fill the battery, I guess an external battery charger won't allow for this.

Does this also affect jump starting then? That’s a bit worrying.

VW Recommends using a VW garage.

I've looked at many vag group forums and indeed the interweb in general because I too was worried at first.
Anything I've read has said EFG & AGM batteries can be charged like an ordinary battery as long as you use a smart charger.
I've also read that on battery manufacturers sites.

I know I’m a bit old school but this is becoming a farce. As soon as the lockdown is over I’ll be looking to unload my all-singing all-dancing Catch 22 VW for something less sophisticated but a lot less trouble :| Go to the Dealer to charge a battery indeed.

They’ll be wanting to set up a Direct Debit next just so’s I can run about town. Bah.

I think I will invest in a c tec trickle charger found one on Amazon about £70
I don't know what v w expect you to do if your battery goes flat at home
Do I have to get my car taken to a dealer just to charge a battery ?

Hi folks.
I have a CTEK MXS 5.0 smart charger which has a program for AGM ( and EFB ) batteries. My battery is a Varta EFB and at some stage I will probably need to charge it using the CTEK if this lock-down continues. The charger handbook has a chart which explains the different charging programs. Under the AGM program it is stated that the charging temperature range is -20degC to +5degC ( -4degF to -41degF ). Surely this must be a mistake and it should read -20 to +50 like all of the other programs. What do you chaps think ?
