I noted the brand of batteries above, but here is the link to the exact battery/charger combo that I purchased. http://www.batteryjunction.com/4parc390reli.html I was wrong earlier when I stated that I didn't believe they were "protected". I see in the description that they are listed as having internal voltage regulators and full PCB protection against overcharging, etc.

I also noted the temperature range -- you know, it's Minnesota, it gets cold here -- I need something that I can rely on even when it gets below zero. If this won't do it, then I need to find something else.
