Is a lead acid car battery the same as a 9 volt alkaline battery?
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
Why does an Alkaline battery last longer than an acid dry battery?
Alkaline dry cells last longer because NH4Cl, an acid found in non-alkaline, is replaced with KOH or NaOH, a base found in alkaline. The Zinc in an alkaline dry cell batteries tends to corrode less in basic conditions.
A dry cell battery produces how many volts?
Depends on the number of cells and the chemistry being used. A 3-cell Alkaline battery would be 4.5V while a 3-cell NiMH would be 3.6V
What is the difference between galvanized and alkalized cell?
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.
What is an alkaline battery?
The "non-alkaline" battery is probably best "defined" by comparing it to the alkaline battery. Both are chemical cells, but the alkaline battery has as an electrolyte a basic solution of potassium hydroxide. (A base is often said to be "alkaline" in chemistry.) The "non-alkaline" battery uses zinc and ammonium chloride, which are acidic, as an electrolyte. The alkaline battery packs a higher chemical energy density than the "regular" or, as it is marketed, "heavy duty" or "industrial" battery. That's why it is generally more expensive and lasts longer.

Where do I buy AAAA batteries?
The AAAA battery (usually read as quadruple-A) is 42.5 mm long and 8.3 mm in diameter. The alkaline cell weighs around 6.5 g and produces 1.5 V. This battery.The AAAA battery (usually read as quadruple-A) is 42.5 mm long and 8.3 mm in diameter. The alkaline cell weighs around 6.5 g and produces 1.5 V. This battery?
Why is car battery called a battery?
Its called a battery because it is a group of cells. In the case of a conventional lead-acid battery each cell produces about 2 volts. To obtain 12 volts, 6 of these cells must be combined, forming a battery. Sometimes the term battery is a misnomer. In the case of 1.5v alkaline "batteries" they are technically just one cell.
Why battery life of a pager is better than a cellphone?
Because a pager is just a radio receiver and not a radio transmitter. A cell phone is both a receiver and a transmitter. A receiver uses much less battery power than a transmitter does. And because a pager's disposable alkaline battery holds more power than a cell phone's rechargeable battery.
How do you determine the number of cells in a battery?
It depends on the chemistry of the battery. A common alkaline or zinc chloride non-rechargeable battery will be about 1.5v per cell. a NiMh or NiCd rechargeable battery is usually quoted at 1.2v per cell, Lithium Ion cells are generally quoted at 3.7 volts and lead acid at 2v per cell. Divide the pack voltage by the individual voltage of each cell and you will find out how many cells are in the pack.
What is the source of alkaline in batteries?
The electrolyte used in alkaline dry cell batteries is usually potassium hydroxide.The main advantage of the alkaline potassium hydroxide electrolyte over the acidic ammonium chloride electrolyte in conventional dry cell batteries is that if it happens to leak outside the battery case it will not corrode the metal parts of the device it is powering (but the leakage still makes a mess that should be cleaned out when replacing the bad batteries with good ones).
How were first electrical batteries charged?
They weren't, they were single-use. Pick the two correct metals, stick them close together in an acidic bath, and they'll deliver a voltage and a current until one of the metals is all used up. No charging required.
What kinds of devices use a button cell battery?
There are several variations of button cell batteries. Some of these include the alkaline, mercury, zinc-air, silver and lithium. Button cells battery types are each distinguished by a unique letter code.
