LFA Battery trickle charger
Folks,
Can I connect the lexus (ctek) charger to the 12v socket in the glove box and keep the battery charged that way rather than directly to the battery in the back?
Thanks

Charging from the 12v cig should not be an issue unless the CTEK's output is over 10A. Most 12v plugs won't power on unless the ignition is on anyways. Any reason why you wouldn't want to connect it directly to the battery?

Charger troubles
I tried connecting directly to the battery but could never get the charger to switch from orange to green. No matter how long I left it, or played with the connections it wouldn't switch over to green. I even tried a second ctek charger I have and the same issue. I was wondering if the car had a current draw on it and so that's why the manual recommended disconnecting the negative terminal clamp and connecting direct to the battery post. I didn't want to do this as I would be resetting everything every time I did this.. Hence the question if I could try the 12v charger and see if this worked for me...
