POWEROWL AA Batteries, 1.5V Lithium Battery 3400mAh, Double A Battery - Pack of 8 (Not Rechargeable)

The best batteries I've purchased for my blink outdoor cameras

5 out of 5, have purchased these many times now for our Blink cameras and Blink Doorbell. Great value in comparison to other 1.5V lithium batteries. Really long life span on them, on cameras which dont get much activity they have lasted about 2 years, and the doorbell which gets a lot of use including motion passing by have lasted about 12 months. Considering these are left in cameras outside, all year round, they dont seem to be affected by the cold. Clearly provide plenty of power with a good lifespan. Available on Amazon prime for next day delivery.

Bought an 8 pack in January 2026, started using them about end of March. I use them in a Blink Doorbell and recently they last almost exactly two weeks. I test them before I insert them in the bell and after two weeks the bell is inop, test the batteries 1.7V. Very disappointed, just bought Energiser batteries

Worked brilliantly.

Have re ordered a few times , good battery life as I use them for my door bell ring , good quality

I usually buy Energiser alkaline power plus, as I find them to be an excellent compromise between ordinary alkaline, and lithium. Good performance and affordable. I mainly use them in a Braun travel toothbrush and a Braun travel razor. But I saw these on offer, and thought I'd give them a whirl. As soon as I changed the batteries in both, to these, I could tell that there was a dramatic difference. I could see, feel and hear that both the brush head and cutter in the razor were running much faster. Both the toothbrush and razor performed better, as a result. Can't comment on longevity as I've only just changed the batteries today but, based on the increased power and speed, I reckon they'll last longer too. I've just ordered another pack👍.

Updated review: I was sent 32 free batteries as an apology which was a lovely gesture. I have now needed to replace the Energiser ones l, and have used these. Hopefully they will have a reasonable life as the first set I ordered from them. This is the second time I have purchase these batteries. The first time although they did not last as long as the Energizer ones, the cost saving still made up for this. However the last ones have not lasted long at all. I think these only lasted a couple of months. So I am now back to buying Energizer again.

I purchased these for my blink doorbell on October 12. They were fairly priced and I was happy with my purchase. The battery was compatible with Blink doorbell. However , they didn't last long. I had to replace the batteries within just three months. The previous batteries that I used were from Duracell. They were too expensive but lasted for more than eight months. I do not recommend Power owl Lithium battery for blink video doorbell unless you are OK with changing them frequently.
