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.
Bu iyi bir soru mu?

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.

If you disconnect the "C" wire (probably blue) it will probably drain. Might take several days and inevitably will die at 2 am when it's 95 degrees out and you will wake up in a hot sweat! Personally I think that whole "memory" thing with batteries is left over from old NiCAD batteries and likely unnecessary for this application.
@nicksartor Nowadays the charge/drain instructions are not for the benefit of the battery "memory", but rather for the sake of battery health calibration to establish a full/empty baseline for monitoring the battery charge.
