I have a trail camera in my backyard to see what critters sometimes dig up my lawn. Since the trail camera is left outside in all weather conditions and temperatures I needed something better than traditional alkaline or rechargeable batteries. I saw these Blinkspower Lithium Batteries and decided to order them.I received four lithium batteries shrink wrapped together and in a small box. The batteries claim to have a shelf life of 20 years and are stamped with a date of 2043-12. The batteries are stamped as 1.5V but I checked the voltage and each battery came up as 1.82 volts. They also have a claimed rated capacity of 3500mAh.The listing claims that their brand of lithium batteries lasts 5x longer than alkaline batteries and 1.5x longer than others lithium. Of course I have no way of testing this claim. The listing also claims that there will be no leakage from their batteries, a claim, that if true, would be a great positive selling point. Imagine forgetting to remove the batteries from a device and not opening it for several months or years later and not be faced with a corrosion nightmare.I have been using them for about three weeks now in my trail camera and they are performing well so far with no issues. Because of my relatively short term use of these batteries I can't make any kind of comment on their actual longevity and durability (especially in very cold weather).These batteries are not rechargeable.Overall, after a very short use time they are performing up to expectations. I can only hope that the claims from the manufacturer turn out to be true.

The fourth purchase of this product , the batteries last a long time in my trail camera ,about 1.5 months , great product a little pricy but got to have the power. For return customers wish they had a discount program .

Since the placement of my camera is hard to reach, long battery life is super important to me. I have had no issue's using these batteries!

The batteries are great, they last for months. I have a subscription for them with Amazon and they last longer then the time between delivery.

They seem to work fine and were delivered on time.
