Temgrumpy Report post Posted December 16, 2023 I have a 2019 that I might have to leave in Michigan for the winter. Does any one have experience with winter storage? I have used battery tenders on 12 volt batteries, but have no idea how to properly maintain the main battery during winter storage. Any help would be appreciated!

MeeLee Report post Posted February 6 They say to generally not store the ev battery at full charge when storing for longer than a few weeks. Ideally your hveb should be about 50% charge. Don't worry about it failing. So long the 12v battery works, it can jump start the engine which will start the charging process. Ideally you will want to disconnect the positive terminal on the 12v battery, (and keep the trunk open, if you want easy access to the 12v). I think the 12v only needs to be charged one day a month or so. Without the positive terminal connected, it won't lose much charge over time. 1 Temgrumpy reacted to this Quote Share this post Link to post Share on other sites
