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.
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
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.
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?
What metal is oxidized in the most common dry cell?
In the most common dry cell, which is the alkaline battery, zinc is the metal that is oxidized. When the battery is in use, the zinc undergoes oxidation at the anode, releasing electrons and generating electrical energy.
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.
Is a mercury cell a type of alkaline cell or a carbon zinc cell?
A mercury cell is neither a type of alkaline cell nor a carbon-zinc cell. It is a specific type of primary battery that uses mercury oxide as the active material, providing a stable voltage and long shelf life. Unlike alkaline cells, which use potassium hydroxide as the electrolyte, and carbon-zinc cells, which use a zinc anode and carbon cathode with an acidic electrolyte, mercury cells have distinct chemical compositions and applications.
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).
What type of electrochemical cell is used as an energy source in a flashlight?
A flashlight typically uses a galvanic cell, also known as a primary cell, to provide energy. This type of cell converts chemical energy into electrical energy through a spontaneous redox reaction. The most common type of galvanic cell used in flashlights is the alkaline battery.
