My 2013 Leaf S ran its 12v battery stone dead in about 36 hours last Sunday-Tuesday. Unplugged it after charging on Sunday, stone dead Tuesday morning. I knew something had changed since my battery tender was no longer able to get the battery up to the float voltage which turns the light from red to green. (It's a little one, only puts out 750ma in charge mode).
Today I did some "parasitic drain" tests with interesting results. The car was showing 1.06 amps with the EVSE plugged in, and .98 amps unplugged! This is WAY over the 125ma which is normal and which the car showed when I first got it. Removing various fuses produced no significant results. Finally I disconnected the battery for about a minute. Reconnecting, I showed a .98amp momentary drain, heard a relay click in the large square fuse box that's conveniently mounted upside down. Now the drain reduced to .63 amps. After a minute and 20 sec, the drain dropped to a normal 125ma! I tried the test a few times, same result. A .98 amp drain would definitely run the battery down in less than 2 days.
Now I have to ask, "why did it do this?" I will be in contact with Nissan and the dealer and post any info I get. I suspect this issue may be a previous poster's problem also.
Read my further discoveries. Also, looks like someone else has had the same problem. I don't think the bluetooth is ever completely "asleep."
