Totally ironic, but today we ran out to my in-laws to drop off groceries. It is about a 25 minute drive, mostly highway. We brought their groceries in, talked to them from the porch for maybe 10 minutes and went to leave and guess what, the Leaf was dead. I thought "You have got to be kidding me", honestly it was less than 15 minutes. So I flipped the back seat down, crawled in the back (hatch wouldn't even pop open), grabbed the battery (12v 9Ah SLA) and 10mm wrench. Plugged the battery in parallel had my wife try to start it, it lit up like a x-mas tree. I had her shut it off, disconnected the neg from the 12v battery and had only the sla battery on and she tried again and it fired right up. Reconnected the main 12v with a tiny spark, disconnected the SLA and put it all back in the trunk and drove away.
So what the heck, I did charge the 12v Saturday morning (2 days ago) full, only took about 4 hours at 2 amps to get to float. But how was it not charging the 12v while we drove out there? It is currently charging the traction pack since we got home with 30% and of course the 12v is showing 13.98v. I will bulk charge it again once the car is done charging.
I am really tempted to add a battery up front with knife switch to parallel it to the other battery. I thought about a solenoid with a momentary switch in the cabin to parallel them, but that would be work, although my wife would like that if it is cold or raining, she has "jumped" it a couple of times herself. But what if one of our kids has the car, which luckily hasn't happened, yet, they would have to call and I walk them through the process.
