So the two sets of Tenergy LiFePO4 CR123a batteries I use in my MagTac are not holding much of a charge anymore after 5 years of use. So I go to BatteryJunction.Com to get some new ones and find that they no longer sell them! I'm hardly finding any LiFePO4 CR123A batteries anywhere now. Finding plenty of the Li-Ion ones though, but I was told those were not as safe which is why I bought LiFePO4 when I bought the flashlight.
