Yes, they will work. Spider Fire are cheap batteries and I don't know what brand of RCR123a batteries you have on hand.
The VV Reo deserves premium batteries, in my opinion. AW is the recommended battery because AW has a reputation for very good and consistent QC on the batteries they sell. AW doesn't manufacture them, but it's my understanding that they do test them and weed out the lesser performing batteries before applying their heat shrink and label and offering them for sale.
Thanks for the Info. I just have so many of them that I hate to see them go to waste. I will buy A W and save these for emergencies.
