I want to know about different kind of batteries used in power UPS's,their characteristics and differences.

There are Lead Acid type, sealed batteries, Nicad batteries etc, describing all here is difclt, try web sites like wikepedia etc

Take a look at your electric bill.  It will tell you what your average daily electrical consumption is.  You will need some form of electrical production that meets that amount every day.\n\nMost home battery systems use 12 volt batteries connected in series to obtain a high voltage.  Then the batteries are connected to an inverter to produce 120 volts AC.  You can buy inverters that are rated for about 5 kW.  If you have a pair of those, one on each leg of your electrical connection (L1 & L2) it is good for 10 kW of power which should be enough for a most homes.  The reason for being able to handle high power is that sometimes the refrigerator, A/C, stove and TV may be on at the same time and draw a lot of power even if it is for a short time.\n\nThe size of your battery bank will depend on your generating system.  If you can generate continuously, the battery capacity can be reasonably small.  If you are relying on solar and wind energy and have to account for a few days of overcast skies and no wind, the batteries have to be quite large.  Sizing the batteries takes a bit of research.

Battery backup is a battery that can power your computer (and other things, too) for a period of time in the event that your main power source fails (for example, in a power outage during a storm).\n\nThe more common term is "uninterruptable power supply" (UPS). These devices are available at most computer stores. Prices range from $50 to $500 and higher, depending mostly on how long you want to be able to keep your computer running.

In a lemon battery the electrical energy is actually coming from the two different metals that you stick in the lemon. So that's the same as a household battery. The difference is that the juice in the lemon, the electrolyte, is liquid, and in a standard torch battery it is a sort of gel.

They are nearly identical.  Look at the technical data sheets for a AA Alkaline, for example. Pay particular attention to the "Constant Current Performance" graphs on each data sheet\nhttp://www.duracell.com/oem/Pdf/MN1500.pdf\nhttp://data.energizer.com/PDFs/E91.pdf\n\nThey show that both Duracell and Energizer last for 300 hours at 10 mA before dropping to 0.8 Volts

i think its acid..........The kind of batteries you have in your toys and CD player are wrapped in nickel-plated steel. This steel case has a thin plastic coating on the outside. Inside are the three main parts of a battery: the anode, the cathode, and electrolyte. The anode is made of zinc metal, and electricity travels from the anode through a circuit back to the cathode. The cathode is made of manganese dioxide and graphite. The electricity then passes back to the anode through the electrolyte, which is a salt and water solution. Batteries may have other parts inside made of plastic, brass, and other materials. For a look inside a battery, check out this Duracell page.

Volts Per Cell.  I've no idea how many cells your battery comprises, but it's a guidleine to avoid overcharging.

Different chemical species are connected by some means that allows ions to flow between them, but does not allow them to mix.   The different chemical species are chosen so that one of them undergoes oxidation, or loss of electrons, while the other undergoes reduction, or gain of electrons.\n\nWires connect to each of the chemical species and to positive and negative terminals of the battery.  When they are used, electrons flow into the wire from the oxidizing side, through the circuit and return to the reducing side.\n\nA simple cell that shows this flow can be made from a lemon and two different pieces of metal (like a copper wire and a length of solder).  Just push the pieces of metal into the lemon and you can measure a voltage from one wire to another.\n\nCommercial batteries are a bit more complex in construction.

the best for you is to read completely the powerkite manual.\n\n:> peace

Batteries are self-contained chemistry sets, and chilling a battery slows down the reactions within that are slowly breaking down the alkali fluid, thereby preserving the electrical charge longer.\n\nLet's learn about electricity. Electricity is energy released from electrons travelling between atoms. Electrons can travel through any medium (air = lightning, you = electrocution), but they like conductive metals like copper the best, where they travel in a circuit, or a giant circle, between their origin and their destination. Electrons are stored in a battery like a sponge holds excess moisture.\n\nWithin a battery is a chemical (usually an alkali or an isotope-based solution) that retains electrons within like a sponge. Let's just say that battery fluid has properties about it that make it great for retaining excess electrons.\n\nWhen you chill a battery, you slow down the breakdown of the chemical within the battery housing (it will eventually break down into water + a precipitate), thereby preserving the charge that stores electrons. \n\nAnd remember, electrons in motion = electricity.
