with your original question, a battery blanket is the answer.

I’ll rely on my 30 +years of motor vehicle repair experience as a qualified mechanic thanks.

Oh oh

Battery blanket 0r a trickle charger..keeps battery warmer and charged

A good quality automatic maintenance charger ( like an optimate) will do more good.

We run a fair number of engines all year long, and one thing that is becoming more obvious is that the quality of batteries has gone to crap. If a person tries to claim warrenty there is always a reason why your battery failed, and very seldom is the blame put on the battery itself.  
Another thing that is hard on batteries is the technology used on our fuel systems is not up to par, when it comes to starting in these temperatures. If I can start an old Briggs and Stratton engine, that has a simple updraft carberator, on the second compression cycle, why do I watch people cranking engines excessively with no detonation of the gas air mixture.

your talking from experience. A warm battery will out crank a cold battery every time. And as you say a trickle charger has worked for me in Canada for fifty years.

The only suggestion I’d make that hasn’t been mentioned yet is to consider if a battery is made from new or recycled materials. My experience is that the ones made from recycled materials don’t last nearly as long.  
 
I’ve got one in my truck currently, and it’s only 2 years old. Once the cold temps hit it failed. I took it out of the truck, fully charged it, and put it back in. Next day it failed again, so I took it to the retailer. They tested it, said it’s fine. I gave them the benefit of the doubt and put it back in my truck again yesterday. 5 hours later it wouldn’t start. Last recycled battery I ever buy. And I feel like I won’t get warranty either, despite it having another 10 months of free replacement.

If it were me I'd suggest they put tit in there own vehicle and see how well it works.

Obviously it's up to the individual, I'm just offering my experiences. Between my personal experience and work experience, I'm not a fan of batteries made from recycled materials. Especially when a non-recycled option can be had for only $20-30 more and usually lasts longer.
