Replacement Battery for Nest Learning Thermostat
This 3.7V 450mAh lithium cell replaces the original power pack in Nest Learning Thermostat models T200377, T200477, T200577, T200777 and T200877. It fits the slim 48.24 x 42.78 x 2.76 mm cavity without modification. Homeowners and installers can swap it in when the factory battery no longer holds charge.
Steady Output Over Long Cycles
The cell delivers a stable 3.7 volts throughout the thermostat's low-drain daily schedule, avoiding the voltage sag that triggers premature low-battery alerts. ISO9001, RoHS and CE certification confirm consistent manufacturing quality across production lots. It is not suited for high-drain devices that demand burst currents beyond the thermostat's modest draw.
450mAh Capacity Decides Fit
Capacity is the single figure that determines whether the thermostat will run its programmed schedule between recharges. Buyers who need longer runtime or a different voltage must choose another part, as this model provides exactly 450mAh at 3.7V.

Questions about this item
How much power does the 3.7V 450mAh cell draw while the thermostat runs continuously?
The replacement battery simply stores energy at 3.7 volts and 450 milliampere-hours; the thermostat itself determines the actual draw during all-day operation.
What tools or connectors must I already have to fit this 48.24 x 42.78 x 2.76 mm pack into my Nest Learning Thermostat?
No extra tools or connectors are required; the pack is built to the exact dimensions of the original cell so it slides straight into the thermostat's existing battery compartment.
Will this 3701-0001-01 battery work in my older Nest Learning Thermostat T200377 alongside the original wiring?
Yes, the cell is listed as compatible with the T200377, T200477, T200577, T200777 and T200877 models, so it fits the older unit without wiring changes.
