The Nuki Power Pack is equipped with a total charging capacity of 2500 mAh (4.8V DC | 2.5Ah | 12 Wh).
The average battery life of conventional alkaline batteries is around 6 months. The Nuki Power Pack lasts twice as long per charge and is also more environmentally friendly than alkaline batteries.
With an average use with 8-10 locking processes per day, the Nuki Power Pack will last around 12 months until it is completely empty.

At a power level of 20% Nuki will notify you via the Nuki app and directly on the Smart Lock. So there is enough time to replace your batteries of your Smart Lock. In case you are not able to change the batteries or to charge the battery of your Nuki Power Pack in time, you can still use your existing, mechanical key.

How do I know if the batteries or the Power Pack of my Smart Lock are empty?

Nuki will inform you in several ways if the batteries or the Power Pack of your Smart Lock are running low.

Nuki App

As soon as the battery status of your Nuki Smart Lock drops below 20%, you will receive a notification in the Nuki app. You can find the notification by tapping on the bell symbol at the top right.

A blinking Smart Lock

In addition to the message in the Nuki app, the ring of lights on the Smart Lock also signals that the batteries of your Smart Locks will soon be empty.

– Unlocked: The upper segment of the ring of lights blinks three times every 5 seconds.
– Locked: The upper segment of the ring of lights blinks twice every 10 seconds.

Push notification

You can additionally receive push notifications informing you when the battery level drops below 20%. In the Nuki app, you will find the new option “Manage notifications” under the Smart Lock Settings > Manage Smart Lock. Here, you can log in with your Nuki Web account. This is essential, as notifications will then be transmitted through your Nuki Web account. You can activate Nuki Web in just a few steps.

Email notification

If you use a Nuki Web account, there is also the possibility to get notified by email when the battery level of your Smart Lock has dropped to a critical level. To use this feature, simply log into your Nuki Web account and activate the feature “Battery alerts via Email” in the administration of your Smart Lock. You will be notified by email when it is time to change the batteries.
