### ⭐⭐⭐⭐⭐ Lithium batteries can withstand low and high-temperature variations and work well outdoors
*by A***. on February 22, 2024*

If you are already viewing this page, you probably know what you are looking for. CR standard batteries are used in many household devices, from children's toys to fingerprint locks and keypad locks. For example, I obtained these batteries to replace the old ones in my keypad lock. Firstly, they have clear labels indicating the battery's chemical composition and expiration date. The manufacturer promises a 10-year shelf life for these batteries. I cannot confirm or refute this claim because it would require me to write a review in 10 years. However, I hope this is true because I had batteries of this standard that I bought about 12 years ago and only now have used them. They worked flawlessly. The batteries from this manufacturer are packaged in shrink wrap that protects the battery contacts from coming into contact with any metal objects that could cause the battery to discharge. After removing the shrink wrap, the first thing I did was check the battery's charge, and as you can see in the photo, it meets all the standards and even exceeds them. After installing the battery in the keypad lock, it continued to work perfectly, and I did not notice any problems. There are many batteries of this standard on the market, but pay attention to the type of these batteries. Lithium and lithium-ion batteries can withstand low and high-temperature variations and work well outdoors, whereas alkaline batteries are best for electronics that require low or medium power. These batteries are slightly more expensive than alkaline ones, but the difference in their performance is significant. Therefore, I chose this battery for the door lock in our building, as the outdoor part of the lock is exposed to the weather, and during winter, with significant cold, a regular alkaline battery can lose its charge, and you won't be able to get into the building. Based on all of the above, I would give this battery five stars.
