The first electrochemical battery was documented by Alessandro Volta in a letter to the Royal Society of London in 1800. 1780 Volta's friend Luigi Galvani discovered that contact of two different metals with the muscle of a frog resulted in the generation of an electric current.
A battery is made up of a number of cells. A primary cell has a chemistry that is not rechargeable while a secondary cell can be recharged. A battery may have more than one output voltage either by means of taps in a single string of cells or by separate strings of cells. There are many chemistry types used for an individual cell and the cell voltage depends on the chemistry. Typically a battery's capacity is expressed in ampere hours and is for a discharge rate of the capacity divided by 20.

I have included super caps because there is a fine line between a battery and a super cap. These have application as a keep alive power source for electronics. For example the HP Rocky Mountain Workstation computers have a super cap that keeps the clock running for weeks. When they arrive from the factory the clock is correct. The U.S. Army is looking into using them in parallel with a vehicle battery to supply the high current starting energy thus saving the battery from this big load.
2003 - I have seen ads for Super Caps with 100 and 1,000 Farads. But typically each individual cap is rated for only 2.5 Volts. This is a problem because you can not easily add them in series.
Another problem is that most if not all of the super caps you see advertised for hobbyist use are "memory backup" types and can NOT deliver a high current. They are fine for keeping a memory alive that draws a very small current, but no good for supplying any kind of current.

Often a "battery" is made up of standard letter size (AA, AAA, C, D) cells and can be opened up and rebuilt. Unfortunately the small straps that connect the cells are usually spot welded, not soldered, it's a neater way to connect but not a tool in most homes. This is also called Re-celling.

By using a Battery Adapter it's possible to use common batteries to replace either a specialized battery or a larger battery or cell. For example you can buy plastic battery adapters that allow the use of a "C" cell in an application where a "D" cell is needed.
In the case of the SDU-5/E Distress Strobe Light, the original battery was Mercury based and is now obsolete. The replacement battery is very expensive. By using my 5BA Battery Adapter the strobe can be powered by two common 123 photo batteries.
For a number of Battery Adapters made by me see http://www. PRC68.COM
Allow using a number of batteries of one type to look like another type. For example I have one that uses a lot of 9 Volt batteries for the PRC-6. The BA-491 powers the PRC-6 with D cells.

Or and active inverter type that uses 4 "D" cell to generate 67.5 V power supply that fits in the space of a 67.5 V battery
Voltage(s)See the BA-5590 web page for a discussion about when a "12 Volt battery" is really a 15 Volt battery.
Capacity - State Of ChargeFor batteries with a steep discharge curve simply measuring the terminal voltage (maybe with a small load) is adaquate to know the SOC.
For batteries, like Nickel Metal Hydride or NiCad where the curve is almost flat and there are temperature effects, the terminal voltage is not a good method (although if a temperature sensor is part of the battery, not added on) it may work. For these measuring curent * time called coulometry is the best method. http://www.moltechpower.com/ may be a source for more information.

Flash Amps is a measure of the short current that a battery can deliver for a very short time. Although it's not an indicator of state of charge it IS an indicator of what the battery is capable of. Also an important thing to match when making a battery pack.
Max Available Current
In the case of RC batteries the max current available must be larger than the current needed to drive the motor(s).
This did not happen recently (Sep 2013) in the case of the Tamiya Grasshopper RC model dune buggy.
New 3800 mAh batteries failed to power the motor (see video at link above), but another new battery with a lower capacity (Duratrax Onyx 1800 mAh) worked fine. Note the huge difference in internal resistance and calculated short current current in the table below.

Note 1: Smoke came out of the ESR-Cap meter. Maybe I connected it with the leads reversed?
Note 2: Now have SM8124 Battery Internal Resistance meter.
There's no question that the "New" Ni-MH batteries although they have a higher mAh rating (3800) than all the other batteries, they also have a much higher internal resistance thus limiting their output current. The current shown on the bottom line is the battery voltage divided by it's internal resistance. Theyall have been sitting for over a month untouched so the older batteries have discharged more (or didn't take a charge that well before). It's a shame that the battery vendors do not specify internal resistance or short circuit current.
