In this video, I review the XTAR 1.5V 4150mWh rechargeable batteries and test them in real-world smart home devices.

I’ve been using these batteries for several months in smart radiator valves and a Wi-Fi smart cat flap, and the results genuinely surprised me. These are constant-voltage 1.5V rechargeable batteries designed for smart home gear that normally struggles with standard rechargeables.

I cover:
– Real-world battery life in smart home devices
– How they compare to regular AA batteries
– Compatibility notes with devices like smart doorbells
– Whether they’re worth the higher price

If you’re fed up with constantly replacing batteries in smart home devices, these are well worth a look.
