I'm wondering if it's OK to leave the battery uncharged so I can easily get the ICE running to keep the oil circulated when I take the car out (which is now just once every couple weeks). I also have a Nissan Leaf and the Leaf forums say that you shouldn't leave it fully charged in order to preserve the battery life and that the ideal is at about 50% charge. Obviously that's a BEV so you'd want to leave a decent charge on there unlike a PHEV where it doesn't really matter if it runs out. I filled up just before the pandemic hit and my state is still in lockdown so it's just about full still. I've been taking it out once a week or so and flooring it to get the ICE running a couple times. I really wish this car had an "engine hold" mode like my Volt did to force the ICE to run. I've also tried popping the hood while parked to get it running for ten minutes or so. Considering how many times I've gotten FORM since having this van I'm a little disappointed that hasn't kicked in yet. Today I ran down the battery so I could get the ICE on full time and keep the oil moving on the rare occasions that I'm going out. Just want to get some advice if it's OK to leave it uncharged, or at least 3-5% where the engine kicks on anyways.
