Eveready is actually better than Duracell as Eveready lasts over 10 hours and Duracell lasts for around 9 to 10 hours depending on what you're using the battery in.

Rayovac is as good as Duracell as they both last just as long as one another.

Both Rayovac and Duracell are equally good batteries.

Kirkland batteries last nearly as long as Duracell but Duracell lasts at least 5 minutes longer than Kirkland batteries.

Duracell batteries are better than Kirkland batteries but they also cost more so if you're on a budget then the Kirkland batteries will be good choice.

If your AA batteries are draining so fast then it could be that your batteries are not good enough and you need a better longer lasting AA battery.

Some batteries have smaller amounts of power in then than others.

Or your device is a power hungry device that drains the batteries.

Also the chemicals and the plates inside the AA battery will eventually corrode over time which renders the battery powerless.

So if you have older batteries they may not last as long.

The average life of AA batteries is 3 to 5 years when unused and 24 hours when in use.

The average life of a AA battery in use is 24 hours to 28 hours depending on what it is being used in.

Unused AA batteries do eventually go bad and all batteries including the AA batteries have an expiration date.

The AA battery may still work after the expiration date but it will not have as much charge and will not last as long as a new battery.

Most AA batteries as well as AAA and C and D cell batteries will last up to 10 years unused and 9 V batteries last up to 5 years unused.

A battery is a chemical product which produces electricity by chemical reactions at its inside.

When the battery has passed the recommended usage period, the components that make up the battery will deteriorate, leading to performance degradation.

That is why there is an expiry date on the battery.

This loss of capacity (aging) in batteries is irreversible.

As the battery loses capacity, the length of time it will power the product (run time) decreases.

Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage.

Routinely check the battery's charge status.

AA batteries start off with 1.5 volts of energy, but the voltage goes down as the batteries are used up.

Once the batteries dip below 1.35 volts, they appear to be dead, even though they still have a lot of juice left.

The best way to store batteries is to do the following.

Keep them in their original packaging. Did you just buy a new pack of batteries and would you like to unbox them immediately?
Separate old and new batteries.
Store them at room temperature or below.
Keep them away from metal objects.
Be sure to control the humidity.
