When traveling, I use two CR123’s for my Steripen and 1 AAA battery for my flashlight. The CR123’s are lithium ion. The AAA is NiMH (my understanding is that there are no compatible lithium ion AAA’s)
Question:. Can a lithium ion battery charger charge up a NiMH battery effectively and without burning down the house? Would be nice if one charger can charge up two different battery sizes and types.
