It’s hard to beat the cost-to-performance ratio.• Consistent Reliability: Every battery in the pack has delivered steady power with no duds. They fit perfectly in all my CR2-compatible devices and keep them running smoothly.• Compact and Lightweight: Easy to carry spares in a bag or pocket without adding bulk, which is a huge plus for on-the-go use.Cons:• Not Rechargeable: These are single-use batteries, so if you’re looking for a rechargeable option, you’ll need to look elsewhere (though Amazon Basics does offer rechargeable alternatives separately).• Packaging Could Be Improved: The pack comes in basic plastic that’s a bit tricky to open without scissors. A resealable design would be more convenient for storing unused batteries.In short, the Amazon Basics CR2 Lithium Batteries are a fantastic buy—reliable, long-lasting, and budget-friendly.

Using in our ADT alarm system devices. After 1 year I. Measured voltage and had only dropped an insignificant amount. These should last for at least 2-3 years which is better than some of the other brands used over the years. Good value!
