I'm having constant problems with battery charging now that winter is here. My drive to work is about 1 mile, and involves starting the car twice (I have to back the car into the road then lock up while I close the gates behind me). I keep having to boost start the car then give it a decent drive at the weekend or a trickle charge if it's lucky.
The problem is worsened by sharing my usage across 3 different Land Rovers, so they can spend a few days stood idle between journeys. The batteries (all brand new) are getting hammered.
What I want to do (certainly on the Burrt, which may be getting a load of PC kit fitted to it and gets less use than the other two) and probably the Disco and Ernie as well is engineer some kind of electric hook-up as per caravan sites. If I can find someplace to mount the socket (a bit of a challenge on the Discovery, but could perhaps be done at the same time as the LPG filler is fitted) I want to fit a battery charger to each vehicle and have it permanently wired into the battery. So I then get home at night and plug the car into the garage to recharge the battery overnight.
Does this sound feasible? Is there any problem charging the battery whilst it is still connected to the vehicle? It strikes me that it is just the same as the alternator does, albeit more gently.
