Any 5 volt battery with a 2 amp (suitable for charging w tablet) output will work. Preferably one with a switch.

I clipped the leads and put a 4 AA holder in it. If you use alkaline AA, you're at 6V, if you use rechargeable AA, you are at about 4.8v-5V

You have to take them out to charge them, and I put some adhesive backed Velcro to hold it to the side so it doesn't flop around. B8t with the right batteries, you can get a 15 minute charger.

I don't know about fan longevity if you go with alkaline a. I used. Them a few times and liked,the extra air volume .

And I never wore mine for more than a few hours at a time, so can't really speak about battery longevity
