Battery Warmer

Fri Jan 05, 2018 6:47 am

Hello LEAF drivers,
I have a question about the battery warmer in the Nissan Leaf. The manual says to leave the car connected to a power source if the Temp drops below -1 F. What is the best way to do this without actively charging the car? I have a 2015 LEAF S without Nav system.

So far I've been doing this by setting a short timed charge and leaving it on the trickle charger over night once it has stopped charging. Last night I did this, I checked that the car had stopped charging according to the timer, it had. This mourning I came out to the car to find it charging, with indicator lights reading 2 solid one blinking. It was my understanding that the battery warmer indicator light was the same as the 12v battery charging light; just indicator light #3 blinking, is that correct?

Can someone please help me out by offering advise on how to best leave the car connected to a power source to run he battery warmer, if necessary. And is the battery warmer indicator light light #3 blinking?

Also on another note any idea why my charging timer seemed to click back on last night? Very strange.

If you won't be leaving it uncharging (?) in frigid weather for more than two days, you don't have to keep it connected. Just charge it to near 100% or even fully 100%, and the car will power the battery warmer. It uses up to 30% charge per day (but usually more like half that) and stops warming the battery when the charge level reaches 30%. Mine is sitting out there in the frigid wind with only a 12 volt battery maintainer connected, and I'm not worried, having charged it to 100% last night.
