The Altro Smart Lock includes a Li-ion rechargeable battery pack that lasts from 2 to 3 months depending upon the usage. This can be removed from the lock and charged using a USB cable. When the battery level is low, you will receive periodic notifications to recharge the battery pack.
To start your Altro Smart lock, insert the battery pack in the battery cavity present in the Inner unit. To remove, simply pull down the ribbon and pull out the battery pack.
