How to keep your batteries alive on a winter expedition.

Updated: Jun 11, 2020

Have you ever experienced on a very cold day that the battery in your phone drains quickly?

On a winter expedition it is always a question how to look after your batteries, power bank and other electronics. I will share my experience with you how I took care of my electronics and batteries on my expedition over Lake Baikal this year.


When it comes to batteries, Lithium batteries are the one to go with in both cold and extremely warm conditions. They are working a lot better than Alkaline batteries and they are much lighter.

I always take the batteries I will need in the evening and keep them inside my jacket during the day so they will stay warm. The rest of the batteries I keep cold. Once you heat them up they will work. In the evening and in the tent I have them in my sleeping bag.

Solar panel and power bank:

I used an Nomad 14 plus solar panel from Goal Zero & 2, Venture 70 power banks with 17,700 mAh on each power bank.

The power banks works the same as the batteries. I always have one inside my jacket to let it stay warm and in the tent it goes straight to my sleeping bag next to a warm water bottle.

When I charge my power bank, I attache my solar panel on my backpack and drag the cord over my shoulder or underneath my arm and into my pocket at my jacket so the power bank stay warm while charging. I haven’t tried to charge it cold, some people say it will work.

It will still charge a bit slower even in the jacket as the temperature is not super warm.
