Tipsun AA Lithium Batteries, Longer Lasting Energy Double A Battery, 2900mAh Lithium Cells 12 Pack

I bought these to replace the batteries in my blink security system. They lasted one week. Usually they last a year. Do not buy these they are crap.

I’m a professional photographer. Used these in my Nikon SB800 strobe- I use flash on various manual power settings and use strobe on everything I take photo of. I photographed a 4 day long convention and took approximately 1500 photographs. These batteries powered up so quickly, I don’t think the red power light ever went off. Highly recommended, very happy with their stamina!

Excellent price compared to brand name. I’ve only been using these for a couple of months. I have 5 pairs installed in security cameras. Hopefully they work well. I’ve had one battery die after only a few weeks of use but all others seem to be ok.

RECOMMENDATION:I rate these a ‘BUY’. They are reasonably priced for non-rechargeable lithium batteries, and they also come in a nice battery case that can be reused.THE GOOD:1. Reasonably priced vs other AA lithium batteries.2. Come in a nice plastic case that can be reused.THE BAD:1. Nothing so far. Will take a while to see fi the batteries have the extended life that everyone looks for in lithium batteries.

I bought a dozen to try in one of my Reconyx trail cameras. I usually run Energizer Lithium batteries in these cameras and can easily get 9 to 12 months, even through the coldest of weather, recording 10's of thousands of photos and videos. But Energizer prices are through the roof right now. I chanced it with these Tipsun lithiums. What a mistake. I ran them in one camera for 7 to 8 days, with temperatures ranging from the low 40's F to the mid 70's F. I checked them before I put the camera and all cells were just over 1.8v each. When I checked the camera after about a week, I had 344 photo events and the Reconyx battery indicator said they were 1/2 full. So I pulled the batteries and tested them, each cell was down in the 1.6v range. PATHETIC performance. Don't be duped. Spend the inflated money on Energizers I guess, or run alkaline batteries and accept changing them out sooner.

For almost 30 years I've had a battery operated alarm clock that had begun going through an AA alkaline battery at the rate of about one every two weeks. I had removed the battery and stuffed the clock in a drawer and forgotten about it. However, after receiving my order of Tipsun lithium AA batteries I installed one in the clock and for the last two months it has worked perfectly. It hasn't needed any time adjustments or shown any sign of slowing down. I'm really amazed.I have also installed Tipsun batteries in an indoor-outdoor thermometer and in the outdoor temperature sensor. So far, they haven't shown any signs of inaccuracy or a short lifespan.Speaking of lifespan, the shelf life of these batteries is 15 years.These batteries are well worth the price.

They last less than 30 days installed in my blink cameras. Very disappointed in the product. Took to long before realizing the crap life of this battery. Unable to return in the return window. Energizer last 5 to 6 months these maybe 30 days.

Seem to last pretty good
