Compatible Nest Thermostat Models
This 3.7V lithium-polymer battery replaces the original TL284443 cell in Nest Learning Thermostat Gen 3 units including A0013, T3007ES, T3008US, T3016US, T3017US, T3018US, T3019US, T3021US and T3032US. It restores backup power so schedules and settings remain active during mains interruptions.
Included Installation Tools
The package supplies a dedicated tool kit that lets you open the thermostat base and swap the pack without sourcing separate screwdrivers or spudgers. Having the correct bits on hand reduces the risk of damaging the display ribbon cable during disassembly.
Straightforward Swap Procedure
Installation involves removing the display, disconnecting the old pack, connecting the new one and reassembling. The main difficulty is the fragile flex cable between display and base; excessive force or misalignment can tear it. Buyers who need a higher-capacity cell or a different voltage will find this pack unsuitable.

Questions about this item
How often will the 380mAh lithium-polymer pack need replacing in a Nest Learning Thermostat Gen 3?
The 3.7V 380mAh 1.41Wh cell is designed as a direct replacement for the original TL284443; typical lifespan matches the thermostat's own cycle life, so plan on a swap only when the display warns of low backup power.
What is the first limit you hit when the thermostat runs on battery alone during a prolonged power cut?
Capacity is 380mAh at 3.7V, giving 1.41Wh; that reserve keeps the display and Wi-Fi alive for a few hours, after which the voltage drops and the unit shuts down until mains returns.
Does the replacement cell run warmer or draw more current than the factory TL284443 during continuous operation?
It is a 3.7V 380mAh lithium-polymer pack built to the same electrical spec as the original TL284443, so heat output and current draw remain identical to the factory cell.
