Hi,
Any advice on how to safely recharge or maintain the battery. Low battery warning light on, probably through low usage. I'll order a C-Tek 5 charger as I believe that is the one JLR have branded as their product,. Any recommendation on how to safely charge? Straight onto battery terminals? Remove battery (I've heard this is not necessary)? or through the towing electrics using a C-Tek adapter? I've read that some owners leave the C-Tek 5 wired up to the battery and then just connect to mains.
I use a Ctek mxs 10 connected to the tow electrics socket. You could also connect to the jump start terminals under the bonnet.
I wouldn't use the battery terminals as you have to mess around removing the trim in the boot and make sure you connect the -ve to earth not directly to the battery post otherwise the battery management system won't correctly measure the charge in the battery.

I use my car a lot but also run the FBH every morning. Modern cars often don't bother fully charging their battery so I aim to give it a 24-48 hour charge a couple of times over winter to ”condition" the battery.
The msx 10 can supply up to 10 amps so charges more quickly than the 5 but it also has a "supply mode". I use supply mode to power the car and protect the battery when the electrics are going to be on without the engine running e.g. caused by opening and closing the doors repeatedly when cleaning or packing for a long trip.

That's very useful info, thanks. I guess this adapter https://www.ebay.co.uk/itm/13-pin-plug-ada...2797697424 should do the trick. I'll get the Ctek msx 10 as useful for the boat and caravan. Hopefully all as smooth running as it seems to be for you.
If I have had to top the battery up I have put the ctek and mains socket under the partially closed bonnet to keep it all dry.
I like the idea of using the tow socket because you can do it with the car locked but wonder what’s the best method to keep the mains socket and ctek dry?
Hi, I converted my CTEK to croc clips. I just remove the battery trim cover and bring out the battery charger cable by the taillight. Just remember to connect the ground to the vehicle chassis and not the negative terminal. Else you by pass the battery current sensor.

I have a ctek socket hard wired to the battery . I then plug in the ctek lead and close the boot with the wire coming out next to the fog light. I have tried ctek external sockets on my cars and they always fail.
Hi
Thanks for all the info. I purchased the Ctek CT5 stop/start charger from Motorbitz (local to Poole). I've used the positive terminal and earth terminal under the bonnet as the charging point. There is a small hole just above the wheel arch (driver's side) which the Ctek connector fits through, The Ctek charger rests in a plastic tray and plastic bag under the engine protective shield (dry and out of sight). This allows the bonnet to be closed and the car to be locked while charging. All seemed to work without any problems. I'll see if I can post picture next weekend.
