Charging the battery via the cigar lighter socket

[Trev96]

Occasionally my yeti’s battery gets low enough to not be able to start the engine. The problem is that the car has to be nose-in in the garage (no mains electricity), so I can’t open the bonnet.

 I believe that it’s possible to trickle charge it via the cigarette lighter socket using a good 12v battery . Has anybody done this? Would a 12Ah motorcycle battery do?Twice before I relied on a RAC bloke to help me push it out.

I've done it from the 12v socket in the boot regularly and the front lighter socket a couple of times.

No idea what your charger (Battery) would do, but it works with a 7A ctek.

 

I'd be surprised how well the 12v battery would do to charge, only because the chargers all do it at around 14v.
