PallusRechargeable Lithium AA Batteries, 4 Pack 1.5V Double A Lithium-Ion Batteries for Blink Camera, Home Office Device, 3500mWh High Capacity, Super Long Lasting, Over Cycle 1600, Constant Output

Was tired of constantly replacing the batteries on my Blink doorbell. These charge quick and last roughly 3-5 weeks. Would recommend!

After doing some research for the heaviest duty AA lithium battery I came across this brand. So far they work great. They are very heavy duty and since I charged them fully they have barely used any juice in the wifi door lock they are installed in. I would recommend these to anyone who is switching to lithium and needs a heavy-duty battery!

These batteries only lasted a month or more maybe before they needed recharging. I use these for my security cameras outdoors. They recharge so, that isn't a big deal. I just have to climb a ladder to change the batteries and would really like something that lasted a good long time before I have to climb every mountain again. Good value for the money, I am not complaining. I am giving an honest opinion of what consumers needs are as opposed to functionality in our daily lives. These work as promised and no complaints towards the product. Everything worked and is still working just fine.

Backup

I like that it's quick charging and a great purchase for the cost.

Save money.

The batteries work in our Blink cameras

I fully charged the 4 pack overnight. Batteries didn’t even last 48 hours. I used the second two batteries after topping them off and they lasted only 2 weeks. Non rechargeable last months. These are horrible
