Long-Lasting and Reliable Batteries!

dirtrider1004October 18, 2025

The EEMB CR2450 3V lithium coin cell batteries are excellent! They fit perfectly in my car key fobs, remotes, and flameless candles. The 650mAh capacity seems to last a long time, and I haven’t had any issues with leakage or poor performance. The pack of 5 is a great value, and the batteries are fresh and ready to use. Very happy with this purchase — dependable and high-quality! Read more

Good value for the quantity

Donald A. MorganApril 27, 2025

Great value for the quantity you are buying hopefully you'll use them in your lifetime. We have a lot of little remote tea lights. So we never use them but the batteries went dead in them so we needed to replace them so hopefully this year we will use them more often. No problems with the battery if they worked as promised and didn't have any dead ones for the ones that I've used. It is a deal. Read more

Solid Performance but Inconsistent Longevity

AlexMFebruary 28, 2025

I recently purchased the EEMB CR2450 batteries for my devices. They fit perfectly and are strong. I was hesitant to buy a no-name brand, but they work great and at a great price. However, I noticed that the battery life isn't as long as expected. Some users have mixed opinions regarding the long-lasting performance of these non-rechargeable lithium batteries. While some report that they perform just as well as more expensive name brands and last for weeks or even months, others find them to be significantly shorter-lived than their expectations or previous experiences with other battery brands. Despite this, the price is attractive, and they arrived quickly. Overall, I'm satisfied with the purchase but wish the longevity was more reliable. Read more

Easiest Buy

IcabodJanuary 26, 2025

These “coin” batteries often come two in a hard plastic pack. I seem to always misplace the pack and spare battery. These came in a foil strip that prevents loss. Our alarm system has batteries for the sensors. I got up yesterday and had an alert. A battery was low. Then the system asked me if I wanted to know which battery was needed? I pressed “yes” then got the battery data. Copy paste to Prime and got a next day delivery. Then I searched the alarm data and got a neat demo of how to change the battery. Short fast and easy. Oh? I’m supposed to praise the battery? The last one lasted several years and I expect the same. I bought the 5 pack as it was cheaper the the two pack. Read more

Nice replacement

Great replacement for my Samsung SmartThings door sensors. How long will they last is the million dollar question but fits perfectly. Read more

Shorter battery life

jasonDecember 18, 2025

I had high hopes for these lithium batteries, but unfortunately, the battery life has been short in my car key fobs. I found myself needing to replace the battery every one to two months, which is far more frequent than it should be. Read more
