I have two 14500 Ultra Fire with short-circuit and over current protection batts, 900mah, that came with a video/digital camera 14500 charger, also I have two AW IMR 14500 600mah batts and a UltraFire WF-188 charger. My question is, can either charger be used to charge either batteries? I'm thinking yes, but I don't know much about these things, so thought I'd better ask. Thanks.
