17 days agoI bought Xtar rechargeable AA just for the deadbolt cause I got tired of replacing enveloops every few weeks. They last a long time, but when they drop to 1.1v the deadbolt stops working. So, battery level is always 100% until the day the lock doesn’t work.
Not exactly, my schledge deadbolt has zwave so I can monitor battery percentage in HA. The problem is that the Xtar is a constant voltage rechargeable lithium battery with a constant 1.5V output. They drop to 1.1V to signal low charge. When that happens the deadbolt stops working soon after.
