How to drain battery
The iFixit instructions with the replacement battery says to charge, drain, and charge. Does anyone know how to drain the battery in a consistent way and how long does it take to do so. Obviously, reconnecting the thermostat back to the base won’t work since it can charge from the base.
"Hi @sscollis ,
Try disconnecting the power from the base.
As to how long it takes would depend on how much charge the battery has and what the load current is. I don’t know the answer to this."
