    • Battery type is 284449, meaning the battery is 2.8mm thick and 44mm by 49mm long/wide. Capacity 2.1Wh

    • Those are tricky to find, but any 2.8mm battery should fit if doesn't exceed the size. For example a slightly shorter TL284443 fits perfectly

    • YEEY!! We love pull tabs! Just pull them down to detach the battery

    • Here is the battery connector. To disconnect the battery simply pull the connector "up"

    • The battery connector is very fragile, try to take extra care while disconnecting the old battery

There are a lot of sellers out there (on Amazon, eBay, etc) that are claiming their batteries are “compatible” with the Nest E, but they are NOT truly compatible – they are underpowered. You’ll need to find a battery that clearly states that it provides 2.1Wh of power, not just 3.7V. Try searching eBay (I couldn’t find one on Amazon) for “authentic” or “genuine” Nest battery, and check the Wh rating. They’re out there, but can be hard to find. As always, check the seller’s ratings as well… many of those for sale are old and may not hold a charge if they’ve been discharged too long.

That is great advise, thank you! I’ve seen too many underpowered (1.4Wh) batteries sold with poor ratings. It’s hard to find a quality battery.

Thank you for this article. I used it to take out my Nest battery, which I thought was “unserviceable”. The step-by-step instructions were very helpful.

When I try to plug in the replacement battery it immediately gets hot along with the board. It's a model TL284443 not a TL284449 but it has the correct 600Mah and 3.7V. It's a LI-ion polymer battery.

Apparently, the wires were soldered to the battery incorrectly so black was positive and red was negative. The wires were put into the connector in the correct color order but not current order.
