I too found all the comments to be very informative. Decided to order a G2Z last night with a number of accessories.
I have had more battery corrosion issues with Mag Lights than makes sense. I feel a bit safer with the non-metalic casing.
Is the battery offer from SF any better than buying them OTC elsewhere?
Seems like even with a 10 year shelf life it is a lot of batteries to order at one time.
