This thread may not have a snowball's chance in Hell getting resolved, but let's give it the old college try:
I take the vast majority of batteries in equipment on my farm into the shop at home to stay warm and charged, but those in some fixed equipment (door opening and overhead crane winches that are all 12VDC) and quad have cheap Chinese maintainers that work extremely well. BUT: my 24V Cat (snow clearing), excavator and 12V highway tractor need support to be able to crank when cold after being parked for weeks or even months. I have some of the older gray coloured NOCOs that suffer from brittle leads at low temp, but are sealed so can sit out in the weather (TOP requirement).
I just started parking the FLD120 there, and it really needs a smart maintainer, but when I went to my local battery store, the off brand stuff was not suitable for exposure to snow or rain and the 10A 12/24V Noco the guy told me in no uncertain terms I do not want to buy. Why? The new ones have a Li Ion battery and they simply don't work when cold!!!! (So he says but I have to take that one seriously).
So: let's hear from the Northerners - what battery maintainers have decent wire, exposable to rain/snow and actually work when cold???
