This is why I suggested that someone come up with an easy way to wire a switch for the unit, so it only is on when needed.

Just replace the 12v battery with a name brand and be done with it. The OEM battery is underperforming and when the voltage gets to the point it needs to be charged up by the main pack, and the temperature is below a certain point, it can't put out enough power to throw the solenoid to charge itself. Install another decent name brand battery and this problem goes away.

No, not this. Definitely not this lol.

Throwing in a new battery and waiting for the problem to "go away" is not good advice.

LeftieBiker wrote:Given your situation, the best bandaid for you is a hardwired connection through the charge port compartment for a 2 amp or so battery maintainer. Just plug it in whenever you plug the car in to charge, and unplug it when you unplug the charging cable. That will also allow you to leave the car plugged in but not charging for as long as you like. It's what I use, except my Battery Tender JR is only 0.75 amp.


I've wondered if a trickle charger could be installed permanently, and wired to draw its supply power from the J1772 AC lines 1 & 2, whenever the car is charging from an EVSE. You'd need to fuse the charger leads where they connect to the AC lines 1&2; and you'd need a charger which accepts either 120 or 240v.

It's not something I'm going to do, but it seems like it could be done.

I have a 2A battery charger. I attach it while the car is charging. Damndest thing is, when the battery is out of the car, it will complete a charge in a few hours. When the battery is IN the car, the charger goes on forever. I wonder if the leaf is fooling the charger into thinking the battery reads lower than it actually is. I can't say i know much of DC battery physics, but I can say that some programmer booby-trapped my car.

The car is pulling enough power from the accessory battery to stop the voltage from reaching the preset maximum on the maintainer until several hours have passed.

But I didn't wait for anything? I just solved the problem. Pulled the trigger on a decent battery and haven't look back since.
