⚠️ NO. Do NOT use Alkaline or NiMH Rechargeable AA Batteries.
- Why Alkaline Fails: Alkaline batteries drop voltage rapidly in cold weather, causing the camera to report “battery dead” within weeks.
- Why Rechargeable NiMH Fails: Rechargeable AA batteries output only 1.2 Volts (the Blink camera requires 1.5 Volts to power its IR night vision LEDs and Wi-Fi transmitter).
- Official Requirement: Only use 1.5V Non-Rechargeable Energizer Ultimate Lithium AA Batteries.
