Duracell Coppertop 9V Battery, 4 Count (Pack of 1), Long-lasting All-Purpose Alkaline 9V Batteries for Household and Office Devices

Reliable ; Longevity

Good product as Duracell always does good price

They came fresh and work as intended and was a good price

I prefer coppertone for all batteries personally. They just seem to last longer.

They are good batteries, but regrettably they still do die eventually.

These are long lasting and I always have a pack on hand for the yearly battery change in my smoke detectors. Sometimes I need these for other purposes like my Ebow and these have worked for years in it. They're also great for use in guitar pedals. The only problem there is that the battery can drain overnight very quickly even with the pedal off if you have patch cables plugged in on both ends. If you use these with guitar pedals then be sure to unplug your patch cables when you're done otherwise it'll drain the battery overnight even if the pedal is off.

Good value

They work well in my items in my home

Bought these to replace my batteries in my carbon monoxide detector. They last a long time compared to other batteries I've bought in the past. Would recommend
