My guess is that your battery is now sulfated to the point where it will no longer hold much charge. This is the result of the LEAF's charging system not keeping the battery fully charged over the years.DanDietrich wrote:Well, our Leaf just signed its death warrant. Dead again. My 12 volt battery has been running down way too frequently. Yesterday I gave it a good charge from my external charger, and this morning it was dead again. A quick charge didn't help. I unhooked the battery and waited a minute and then hooked it back up. It started fine. Three hours later it is still fine. But tonight? Who knows? Tomorrow? It's all a guess. I am beyond frustrated at this defect. My wife will not drive the car to work because she doesn't know if it will start, and I can't blame her. I have been having problems like ths for three years with a four year old car.
My suggestion is that you replace the battery.
