Which Duracell batteries in general last longer and why?

Question

I am enquiring into the distinction between the following products:

DURACELL PLUS

DURACELL ULTRA M3

Is there any distinction. I've seen Duracell Plus sell for £4.99 at a Budgens. By contrast, I was able to pick up the Duracell Ultra M3 Batteries (which also indicate the power left in the battery) for £3.49 at a nearby newsagents.

So which has more power? Plus or Ultra M3?

Answer 1

right from their web site.

Duracell Ultra M3 has been specifically formulated to meet the demands of the latest high powered devices. Duracell Ultra M3 makes the music last longer, much longer.

The UK’s number one battery brand*offers reliable, long lasting power for your household devices such as toys, clocks, remotes or torches.

as u see above every battery type (from a single mfg) is optimized for a specific job.
going from mfg to mfg, their equivalent usage type may be better than another.
then u must make sure u are getting freshly mfg units. they loose capacity sitting around.

YMMV so all u can really do is experiment yourself.
I don't take anybody word for something because I don't know how they came to their conclusion.

Test methodology makes a difference. Like my car gets 55 MPG while yours only gets 35MPG.
OH did i mention I ran it at a constant 40MPH and u ran yours at a varying average of 80MPH with stops and starts and fully loaded.
