I’ll check that site. That’s the one thing I don’t like about SF is the battery life and the cost.
What attracted me was 1.) price and 2.) the ten-year shelf life! I bought a couple of boxes and at $21. ... a deal! I have good back-up for quite some time.
That being said, I do use all.batteries as a great source for rechargeables, et al ... I like their tenergy house brand. ;-)
