    These 9 volt batteries were on clearance. They are great batteries at a hood price. I should have bought a few more.

    Energizer MAX 9V batteries are fresh, long-lasting and dependable. They are priced very reasonably—while there are cheaper products, none are as much of a value as these. The lower-priced offerings by other manufacturers are not well-made nor as durable.

    Energizer is my #1 go to brand for batteries. These help me keep up my smoke detectors and emergency radio. I wouldn't go with any other brand! Even better when you can get them on a sale every so often.

    I use these batteries in the pickup of my guitar. It's a little bit of trouble to replace the batteries so when I need a new battery I want one that will last for as long as possible so I use energizer.
