Energizer Max - 9V Battery (2 Pack) - Nine Volt Alkaline Block Batteries - Reliable Power for Fire Alarms, Smoke Dectors, Radios, Toys - 100% Recyclable Plastic Free Packaging - 5 Year Shelf Life

Good brand. Good price and arrived relatively quickly.

Item is good well packed and should last long time. Delivery was terrible. Delivery was made at a random time not even close to time slot. Driver was so close to my house at one point, but delivered only 5 hours later. Terrible.

This is the 2nd lot of these batteries that I bought for my smoke alarms as i have 4 in my house. They are long lasting and much cheaper on here than they are in the shops.

I haven’t burned to death yet.Smoke alarms love there new batteries.

It's a battery,did what it was supposed to

Batteries to replace old ones in smoke alarms. Both died at the same time. These are what we used last time & lasted a long time.

Worked as expected. Reasonable price and quick delivery

Excellent
