I'll order the BCR battery replacers later today or tomorrow.
What really drives me crazy is that I opened the box for the Camelback and the tender is missing. I did have some theft a number of years ago but I can't imagine someone opened the box and swiped the tender. I must have put it someplace else rather than back in the box with the engine so I must have put it in one of my storage boxes separately.
I hate it when I do stupid stuff like that.
