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.
