Direct Replacement Battery

The Estry 3.7V 280mAh lithium-ion cell is built to the original specifications for the Nest Hello doorbell and compatible Vido Doorbell Wired models C1241290 and NC5100US. It restores power to a wired video doorbell that has lost its ability to hold a charge.

Verify Model and Part Number

Confirm that your device is one of the listed models and that the original battery carries the 1ICP7/17/26 part number. The cell measures 28.2 by 16.65 by 6.6 millimetres and weighs 30.6 grams, so the internal compartment must accept those dimensions.

Upgrades an Ageing Original Cell

This unit replaces a depleted factory battery that no longer sustains the doorbell during brief power interruptions. The swap is worthwhile when the existing pack shows reduced runtime or fails to charge, and the replacement carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Questions about this item

Does the Estry 1ICP7/17/26 battery ship with installation tools or adhesive strips, or must I buy those separately?

The listing covers only the 3.7 V 280 mAh lithium cell itself; no tools, adhesive strips or connectors are mentioned, so plan to source any required installation hardware separately.

The supplier title lists several Nest models — C1241290, NC5100US and Hello — which one should I match to my doorbell?

Match the original battery part number 1ICP7/17/26 printed on your existing cell; that code is the definitive identifier across all listed Nest doorbell models.

Once installed, what does the 1.04 Wh rating actually tell me about daily runtime on a Nest Hello?

The 1.04 Wh capacity (3.7 V × 280 mAh) is the energy reserve the doorbell draws from between charges; actual days per charge depend on motion-event frequency, Wi-Fi signal strength and temperature, not on the watt-hour figure alone.
