JP234
Having to disassemble the lock to replace the AA battery is a non-starter for me. So is having to remember to carry an extra physical key for the inevitable, a dead battery.
Really getting sick of all the assorted batteries in my life that need constant replacing or recharging. I have to have a box full of AAA, AA, C, D, 2032, 2430. 2025, 312, and spare power tool batteries, to avoid having to go to the store in the middle of some activity. And then there's the rat's nest of adapters, chargers and cables.
