I think I'll heed Washwipes advice and go through another Winter with my CTEK attached.
I have never had any warnings, bongs etc with this car, so what are the early signs of an end of life battery ? I don't want to be stuck somewhere with the damn thing refusing to start, especially with the caravan on the back.


Well worth fitting one of these so cheap its funny and are actually pretty accurate, but more importantly gives you a baseline figure to work from and if that changes you know you may have issues coming sooner rather than later.

Thanks. I've got a ciggy volt meter like that and I've tested it against a DMM within 0.1 volt accuracy. When I get in the car it sometimes reads 12.2 volts, which is low for a lead acid battery (should be 12.8v) but probably due to me doing short runs in the car. When I crank the engine it sometimes drops to 10.5 volts before resuming at 14.5v when the alternator kicks in. MY12 D4 HSE Ipanema Sand

Hi D4mation, I travel to Caldicot (Hour or so from here i live) to where i work. I know its a bit of a drive from Hereford but if you wanted to come that way i could help you replace the Battery and i have JLR SDD so i can reset the BMS for you


Thanks for offer matey.
I've decided to run the battery through another winter and plug in my CTEK from time to time. MY12 D4 HSE Ipanema Sand
