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 glavanix cells, but with much more surface area, to create a much longer-lasting cell.
(PS, 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.
What on earth is a "galvanized battery?
what is the difference between khadi and handloom
difference between tally & fact ?
There is no difference between a donkey and a burrow
There is no difference.

Ok
Alkalized cells use the alkali metal groups of the periodic table or the rare alkaline earth elements. Galvanized cells use any and all metals.
They are nice :)
The difference between the GI sheet galvanized and mild sheet steel is the gauged used. The other difference is the materials used and the galvanization aspect.
Galvanized steel sheet is basically indistinguishable from zinc steel. If you want to buy galvanized steel sheets. You can go to Shanghai Changzheng, which is the choice of most people for its superior quality steel sheets.
The batteries are dangerous to swallow.
PPGI > Prepainted Galvanized, PPGL > Prepainted Galvalume.
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 (IV) oxide (Zn/MnO2). 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.
R20 are zinc-carbon batteries, whereas LR20 are alkaline batteries.
THere is no difference i have answered this question i am the best
Galvanization is a process of treating metal to make it resistant to rusting. A galvanized battery, therefore, is one that is wrapped in a thin tube of galvanized metal. The term alkaline is a chemical and has been applied to a certain variety combination of chemical materials that can be used to produce the desired DC voltage. NiCd, for example, is another chemical term that is specific to the chemical ingredients (nickel and cadmium). Terms like these were introduced to identify newly developed batteries that would last longer than those produced with no attempt to describe the chemical ingredients.
None! 9v1 = 1 battery, 9v2 = 2 batteries :)
