Duracell Coppertop 9V Battery, Long Lasting Power, 6 Pack

This is the best product I've ever used in what ever I use it for and I never had any problems with anything.

Duracell batteries provide the reliability, quality and lasting power that you need in a battery. I have been using Duracell for many years and will continue to do so. Walmart offers a good pricing and prompt delivery. An all-around great deal.

Great value for batteries

I like the batteries. However they took way too long to get here. I would not recommend this shipper.

We use Duracell 9v batteries in our son's toys always. Especially this grave digger monster truck RC car. He's constantly forgetting to turn the monster truck off after he is done using it and Duracell 9v seems to last forever!! This makes the quality of these batteries a 10/10 for our house!

The best there is! The only one I trust for my smoke detector, the one and only! This has been my favorite brand of battery for so many years. Quality, performance, assurance, workmanship and always lasting power is what you can expect from Duracell.

These little power blocks are absolute lifesavers when your favorite gadgets suddenly stop working. I always make sure to keep a few stashed away in my junk drawer for those inevitable moments of need. They are incredibly easy to swap out and get your electronics running again in a matter of seconds. It is honestly such a relief knowing you have reliable energy ready to go whenever something dies. You really cannot go wrong with having a steady supply of these essentials on hand at all times.

they don't test as good as other similar batteries

Poor shipping packaging, large box of batteries came in a plastic envelope and original battery package was torn apart.
