Let's talk about this High Power Super Alkaline Button Cell Assortment. First off, the variety is impressive - AG3/LR41, AG4/LR626, AG5/LR754, AG10/LR1130, AG13/LR44 all in one pack. That's 50 batteries total, which seems like a steal for the price.

In real-world use, these batteries have been a lifesaver for my kid's musical books and various small electronics around the house. The LR44s work perfectly in my digital thermometer, and the LR41s fit my car key fob like a glove. No more last-minute store runs when devices die!

However, there are some quirks. The packaging is frustrating - the cardboard backing is way too sturdy, making it hard to pop out individual batteries without using scissors. And like several reviewers mentioned, there's no expiration date anywhere on the package, which is concerning for button cells that can lose charge over time.

The assortment isn't perfect for everyone. If you need a specific type (like A1 cells), you'll be disappointed. Some users reported receiving dead batteries (though mine worked fine), so quality control might be hit or miss.

For the price though? It's hard to complain too much. Even if you only need a couple types from this pack, it's often cheaper than buying them individually at retail stores. Just be prepared to store the extras properly since they're now all mixed together after opening!
