A:Answer The Blink cameras are shipped with two non-rechargeable AA 1.5v Lithium batteries and they’re easy to replace when the time comes. Simply slide open the battery compartment, take out the old batteries, and insert the new set. Blink camera batteries should be replaced by Energizer Ultimate 1.5v Lithium AA batteries or the equivalent. Note: Avoid using AA Lithium Ion or Li-ion batteries as these will carry a higher voltage and may cause issues with your camera. You also want to avoid Alkaline based and rechargeable batteries, as they may cause issues with your camera.
