It's normal for a Gen I Leaf - especially if the 'water tank' heater is running in the background, using energy to preheat the coolant on cool days.Thinking back... my LEAF never gave me more than about 70km on a full charge when using the highway or about 100km when taking back roads. I thought that that was normal. Going uphill or driving at highway speeds caused the range to fall drastically.
My experience in Phoenix: The original and replacement battery in the 2011 lost capacity quickly in the hot climate (original was down to 8 capacity bars after 2 years; Nissan replaced the battery and the replacement was down to 11 capacity bars when the car was totaled by someone who failed to stop for the traffic light I was already stopped at). The "lizard" battery in the 2015 did much better, but usable range was dropping rapidly due to a few weak cells by the time I traded it in. The larger battery pack in the 2019 is doing better than the previous cars after almost 2 years and over 30,000 miles of use. The heat is on with the predicted high of 115 degrees F next Tuesday.martincanuk wrote: ↑Wed Jun 09, 2021 9:59 pmThanks for your input Gerry.

Going uphill or driving at highway speeds caused the range to fall drastically. Right now anything over 70 real km would seem great to me! Perhaps the battery has had a weak cell or cell pair from when I first bought it, in 2015 I think. I see you live in Phoenix. Did you get the upgrade to the 'lizard pack'? I have visited with my nephew in Gilbert and I know how hot it gets there.
The Gen 1.0 does indeed use resistance heat to heat coolant. It is a problem because it does it almost all the time, unless you turn off the climate control. There was - and may still be - a heater control switch available through a member here for the Gen 1 Leafs. The Gen 1.5 leaf, introduced here in 2013 (but with the old battery chemistry retained until April of 2013 in the US) uses a direct to air resistance heater, and further incorporates a "heat" switch that turns off just the heater. A heat pump also became part of the system for higher trim models in 2013.What is 'coolant' used for in my LEAF? I wondered what the liquid filler tank in front of the 12v battery was for. I thought that the cabin heater worked by heating up a resistor but is that resistor residing in a water tank?
