Replacement battery for Nest Learning Thermostat

The Cameron & Co DS-CS-NLT200SL is a lithium-polymer cell built for the Nest Learning Thermostat 2nd Generation and 3rd Generation, plus the Thermostat E. It matches the original 3.7V .38Ah specification and fits the A0013, T3007ES, T3008US and T4000ES models. Homeowners restoring a dead thermostat will find a direct drop-in part. It is not for users who need a higher-capacity pack or a different voltage.

Sustained power delivery for always-on climate

The 1.41 Wh cell supplies the low continuous current a smart thermostat draws day and night, keeping Wi-Fi radios and sensors alive without brown-outs. Li-polymer chemistry holds voltage steady across the discharge curve, so the display stays responsive through heating cycles. It is not for devices that demand high pulse currents or rapid recharge rates.

Slim 2.90 mm pack installs in minutes

At 48.60 x 44.10 x 2.90 mm the black pack slides into the thermostat base without tools; the connector aligns with the original GB-S10-284449-0100 and TL284443 sockets. The tight clearance means bent pins or a mis-seated connector are the only common issues. It is not for enclosures that require a thicker battery or a different pin pitch.
