Great battery alternative

5 out of 5 stars

Great battery alternative
Having used these batteries for an Arduino project, they are a great alternative to retail batteries. Fit and function is the same as the higher priced alternatives. Quality and longevity are equal to named brand, but at a fraction of the cost. Would recommend.

    Work fine and reasonable comparative value

    Reviewed in the United States on January 29, 2026

    Model: CR2450-10Verified Purchase

    So many choices, so many different package sizes, so many manufacturers … overload !

    I shopped this cell size to find a reasonable price with reasonable ratings for at least a 4-pack. Turns out, value gets better for larger package sizes so I ended up buying what may be a 6-8 year supply rather than the 4 cells that I needed right now. Crazy thing is, it was about the same price and a better long-term value as long as the shelf life is at least a couple of years. Unless the pricing changes universally, figure about 50 – 75 cents per cell as a rough guide for a decent battery (unless you go mega package size). Got them and dropped two of them into the two wifi garage door position sensors. They work fine and the control app for the garage doors shows both are at full power. I’m at 5 stars now based on overall value and functionality when delivered. If they go flat faster the prior cells, I’ll update. Otherwise, no problems.

    Keep in mind that you do get a better value with a larger package size. It was only about 70 cents more for the 15 pack and about $1.50 for the 20 pack. That was hard for me to resist but even the 10 pack was already way more than I needed so I held back and went with the small 10 pack. I will also note that I may have a slight brand bias. I tried some of Granicell’s AA’s in the spring and they have been working fine so I did have some positive brand recognition with these compared to all the other new brands.

    Got these for MyQ garage door sensor. Worked as expected. The date of manufacturing is just 3 months old. Love getting fresh stock.. especially batteries.

    I replaced the old battery just few days ago. So I cant say about battery life. Will update this based on my observation in 4-6 months.

    I am so tired of being caught off guard by the battery in my car key fob dying on me. You have to out and sort through some rack of these types of batteries that all look the same! I bought a package of them with this purchase at a fraction of the cost and stored the rest in the fridge.

    Well the package was delivered with no damage or issues. I found the product to be to my satisfaction and the batteries worked well for what I needed them for. Longevity is another issue and can only be assessed over time but at the moment I'm satisfied with the product. I was satisfied with the delivery and the ordering process. For the price that I paid I got more than what I expected and I'm fully satisfied with that.
