MAX 9V Batteries (2 Pack), 9 Volt Alkaline Batteries - Packaging May Vary

When it comes to powering the most critical devices around my home, I always reach for Energizer MAX 9V Batteries. I bought this convenient 2-pack specifically to swap out the old batteries in our smoke detectors and carbon monoxide alarms, and they perform exactly as expected every single time. The peace of mind you get with these alkaline batteries is unmatched. They have an incredible shelf life, holding their power for up to 5 years in storage, which makes them perfect to keep on hand as backups. They are designed to protect your expensive electronics from damaging leaks, so I never have to worry about them ruining a smoke alarm or a guitar pedal. Bottom line: Energizer is a brand I trust implicitly, and these are always great batteries that deliver long-lasting, consistent power.

Reliable, long-lasting batteries that work exactly as expected. Good quality and dependable performance. Energizer never disappoints.

These were a gift to my son and his wife for Christmas. Along with other sizes of the same brand. I bought so many toys that took batteries and Energizer has always had the best battery life as far as I'm concerned. I would say they were the best value for the money due to how long they last.

very good

It's a 9-volt battery

I bought them because I wanted to put them in smoke detectors. They have a great battery life. Very easy to use. Fit perfectly. I've never had a problem with them.

Not much to say other than energizer has been a solid manufacturer of high quality batteries for years. I use to cheap out and by the off brand batteries, but I’ve found that they don’t have nearly as long shelf life and at times I’ve even seen them leak in action which destroyed a tool of mine due to corrosion. These just work no fuss, simple, and none of the problems I’ve seen with off brands. Definitely recommend going with reputable manufacturers when you need the power for whatever tool your working with.

Exactly what I ordered

Fast shipping, good battery

can't review since it just arrived, but it is what was advertised and came on time.

BATTERIES WERE FRESH..

These batteries were ordered for Kidde CO2 alarm as per Kidde recommendation in their user manual. They were ordered after experiencing some difficulty with other brands. Have had good results using Energizer in car fob as well and they are a little less expensive than Duracell which I expect would perform equally well. Some of these electronic devices are pretty fussy about the battery they like.
