A:Answer With regular use*, your Blink cameras will last a very, very long time on a single set of 2 AA lithium batteries. This incredibly long battery life is made possible through a proprietary chip technology available only in Blink cameras. *Two AA lithium metal batteries last up to two years, based on typical use of Live View, motion-activated recording, and two-way talk (only available on XT2). Battery life will vary based on device settings, use, and environmental factors. Use of two-way talk will reduce battery life.
The cameras are shipped with two non-rechargeable AA 1.5v Lithium batteries. Blink camera batteries should be replaced by Energizer Ultimate 1.5v Lithium AA batteries or the equivalent.
