Yeah I assume it is a coincidence. 
check again in a few weeks and see if that’s still the case.
Yeah, I plan to replace my batteries, though since they are rechargeable batteries and it starts at 5%-6% battery when fully charged, I basically ignore the battery percentage until they actually refuse to lock/unlock anymore first. When I switch them out again I’m going to try using Duracells again and see if I am getting issues like others are reporting in this thread:
If so, I will plan to report the issue in October’s Fix-it-Friday event.
But first, I’m probably going to try to let these rechargeables die first Otherwise I’ll try swapping them out at the beginning of the month.
