Charge Your 12-volt Battery Guide

A 12-volt lead-acid battery Charger for Cell Phones is made up of six cells, each cell producing approximately 2.11 volts that are connected in series from POSITIVE (+) terminal of the first cell to the NEGATIVE (-) terminal of the second cell and so on. Each cell is made up of an element containing positive plates that are all connected together and negative plates, which are also all connected together. They are individually separated with thin sheets of electrically insulating, porous material "envelopes" or "separators" that are used as spacers between the positive (usually light orange) and negative (usually slate gray) plates to keep them from electrically shorting to each other. The plates, within a cell, alternate with a positive plate, a negative plate and so on.
You can charge a 12-volt battery in several different ways. As long as your Battery for Nokia is in good working order and doesn't have a bad cell that would prevent it from holding a charge, you will be able to use all the following methods to charge it.
1.Hook up the dead battery to a 12-volt car battery charger. Written clearly on the control panel at the front of the charger, there are between one and three settings that enable you to either: "trickle-charge" (2 amp) your battery; rapid-charge it (50 amp); or use a medium (10 amp) setting. Trickle-charging is the best choice for a lasting charge. Most 12-volt Battery for Nokia X2 chargers have a switchable setting on the front control panel allowing you to charge both low maintenance 12-volt batteries and deep-cycle marine batteries.
2.Use your car as a charger. Charge your 12-volt battery by starting your vehicle with a good battery, then manually removing the good battery while keeping the engine running. Hook up the dead battery in its place to charge it while the motor is running. A 15-minute charge should place enough power in the battery for it to be started again.
3.Reach for the jumper cables if you encounter a dead battery while you are on the road. A jump from another vehicle will enable you to get to a garage or an auto-parts store to have your battery tested. Simply place the positive (red) alligator clamp on the rescue car battery's positive terminal while the driver runs his engine. Clip the negative (black) alligator clamp on his negative battery terminal. Keeping the two alligator clamps on the opposite end of the jumper cables apart to avoid sparking, proceed to place the corresponding positive (red) clamp on your positive battery terminal and the negative (black) clamp on the negative battery terminal or post.
The most common plate in use today is made up of a metal grid that serves as the supporting framework for the active porous material that is "pasted" on it. After the "curing" of the plates, they are made up into cells, and the cells are then inserted into a high-density tough polypropylene or hard rubber case. The positive plates in the cells are connected in parallel to the external POSITIVE (+) terminal and the negative plates in each cell are connected to the NEGATIVE (-) external terminal. Instead of pasted Lead Oxide, some batteries are constructed with more expensive solid lead cylindrical shape(spiral wound); Manchester or "Manchex" (buttons inserted into the grid); tubular; or prismatic (flat) solid lead (Planté) positive plates. The case is covered and then filled with a dilute sulfuric acid electrolyte.
The Nokia battery is initially charged or "formed" to convert the active yellow Lead Oxide (PbO or Litharge) in the positive plates (cathode) into Lead Peroxide (PbO2), which is usually dark brown or black. The active material in the negative pasted plates (anode) becomes sponge Lead (Pb), but with a very porous structure which is slate gray. The electrolyte is replaced and the battery is given a finishing charge. A "Wet charged" battery is a wet lead-acid battery shipped with electrolyte in the battery and a "dry charged" battery is shipped without electrolyte. When dry charged batteries are sold, electrolyte (battery acid) is added, allowed to soak into the plates, charged (or "formed"), and put into service. This avoids having to maintain the batteries until they are sold.
Attention!
Always carry jumper cables in your trunk to use in emergencies.
Always hook up your battery terminals correctly, as the alternator may be damaged if the battery is hooked up backward.

Is three 9 volt batteries any different in voltage than one 9 volt battery?

Is three 9 volt batteries any different in voltage than one 9 volt battery? Can anyone answer? If I have three 9 volt batteries connected together to one device, does that mean I am using 27 volts?

It depends on whether you connect them in series or in parallel.

If you connect them in series (+ on one battery to the - on the next battery, then + on that battery to - on the next, etc.), then the voltage increases but the capacity stays the same.

If you connect them in parallel (all + together, all - together), then the voltage stays the same but the capacity increases.
