Best 9V Battery
Energizer makes a quality battery especially when it comes to 9V batteries, they always last a long time. I have tried other brands like Rayovac, Duracell and store brands on occasions but always come back to Energizer.

Price should be a little lower than Duracell
They have as much power as any other brand and the charge last almost as long as Duracell with a similar price. The package is good , the batteries don’t overheat like some of the off brands.

Enerrgizer Max Alkaline 9 Volt Batteries
I love these batteries they last alot longer then the other ones .I have them in my lanterns at night so I can see and I don't have to replace them every week. They don't leak I don't like battery acid on my things.

Powerful batteries ⁷
Nine volt batteries are very easy to use and I used to see them in a lot of items that require batteries, but recently I haven't seen as many being used battery required products. I bought a pack of four 9 volt batteries about five years ago and I still have three batteries left. Im not even sure what i bought them for. Lol.

Energizer 9V
We use these batteries for remote control cars for our kids and they work well and last a long time. We rarely have to change them. They had a lot of power as well.

Corroded. Got through drive up and one of the batteries was corroded and unusable. I used one of them so my fire alarm would stop beeping, so can’t return it.

Perfect for small appliances!
The 9V Energizer battery is perfect for small but mighty appliances! I've used this particular battery for years in my smoke detectors, carbon detectors, and in my stuff finding tool. I've never had to deal with any leakage, no power surges messing with the quality or battery life and I've never had to second guess what size I need for my small appliances due to the battery remaining the same in size and quality.

Good deal!
Bought these for the battery powered smoke detectors. It’s been over 9 months since I last replaced it and it hasn’t chirped since. They’re easy to find
