Since Duracell battery is rechargeable it reduces household waste and lessens the impact disposable batteries have on the environment. A Duracell battery comes in a simple design keeping costs low and delivers a rechargeable battery capable of meeting the demands of low cost, safety and durability. Duracell Laptop batteries are specifically designed for each laptop brand and model. Duracell battery currently provides the best performance for notebook computer, iPod, or iPhone. This standard battery technology is also used in many other devices.

Energizer >The Energizer Lithium battery is designed for use in high-tech devices that quickly drain standard batteries. Energizer produces Ultimate Lithium and Advanced Lithium AA and AAA batteries, and calls them the longest lasting such batteries in the world. They are designed to give optimal power and life to products such as digital cameras, gaming accessories and radios. Energizer lithium batteries have a shelf life of 10 years.

THE DIFFERENCE BETWEEN DURACELL & ENERGIZER CELLS:
There are very slight differences in the batteries, and some people may suggest that Duracell batteries performs better when used continuously, but Energizer will have a longer life if not used continuously. Energizer and Duracell batteries of various brands were tested under varying ambient conditions. The results we are presented below.

DIFFERENCE BETWEEN GALVANIZED & ALKALIZED CELLS:
Galvanic cells are classified as either primary or secondary. A primary cell is used once and then thrown away when exhausted. A common example is an alkaline dry cell.

Alkaline cells are a subset of galvanic cells. Galvanic cells are more generic and use any metals. Alkaline batteries are a type of disposable battery or rechargeable battery dependent upon the reaction between zinc and manganese oxide. The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide, as opposed to the acidic electrolyte of the zinc-carbon batteries which are offered in the same nominal voltages and physical size.
The old galvanic power cells that we used in our flashlights, and so forth, actually had a thin wrap of zinc alloy as one of the two electrodes. The other electrode was composed of thin sheet material with an acid paste applied to it and wrapped round and round with the zinc.
Plating something with zinc to make it rust-proof is called galvanizing, which has nothing to do with your question, other than to explain where the term comes from.

Alkaline power cells use an alkaline or basic paste rather than an acid one, in a structure that is much more delicate than the galvanic cells, but with much more surface area, to create a much longer lasting cell.

They are not batteries until 2 or more power cells are connected. It's like a battery of psychological tests, a battery of heavy naval guns, or the old baseball term, battery, which meant the pitcher and catcher working together as a team.
