Interesting enough on the NOCOs in low temps. I bought two NOCO chargers NOCO Genius GEN5X1, and a Genius 2A. 2A is installed on my 19 Ram and the 5A is installed on my Freightliner M2. The 5A was installed during a good cold snap during Christmas. The first night it was installed was approx. -40C to -45C. It was not happy when I plugged it in battery's were not frozen and has been charged for 13hrs. That said the thing has never let me down since. I know lowest operating rand is -30C but has been that cold previously and worked fine. The charger module is in the cab on the M2 and the Dodge is under the hood. Both work perfect.Guess I should set mine up on the home automation like the block heater (currently below 20F). Pretty rare it gets -4F here in the winter though.
That said, I saw this on a forum (so it must be true right?):
I've a little BatteryTender Junior brick I keep on my ATV (under a cover) all the time and it's not supposed to be used below 32F and has never had an issue.
ETA: Actually, I've been thinking about using an HA rule to cycle the block heater on/off depending on my presence, the weather, and perhaps even add a temp probe to monitor the block temp... Life360 broke their API so I'm trying to make some other presence detection options work reliably first.
