Most circuits are just fine with a big battery at the right voltage. The resistance of the circuit automatically limits the current when the right voltage is applied. Occasionally there's a slightly different situation. Some of those cheap plug-in DC supplies that come with electronic devices are designed to put out the right voltage only when hooked to a device that drains the right current. If the drain is too low, the voltage drifts up some. Batteries aren't like that, however. Their maximum voltage is just a little above the rated voltage, well within the tolerable range for the circuit.

In many devices that use batteries -- such as portable radios and flashlights -- you don't use just one cell at a time. You normally group them together in a serial arrangement to increase the voltage or in a parallel arrangement to increase current. The diagram shows these two arrangements. The upper diagram shows a parallel arrangement. The four batteries in parallel will together produce the voltage of one cell, but the current they supply will be four times that of a single cell. Current is the rate at which electric charge passes through a circuit , and is measured in amperes.

Here are some conservative power ratings for good quality alkaline-manganese dioxide batteries available at the local grocery store. The battery capacity will be better with lower drain currents. To determine the battery life, divide the capacity by the actual load current to get the hours of life. The voltage is near 1. Alkaline cells exhibit a slightly increased capacity when warmed and the capacity drops significantly at temperatures below freezing.

An AAA or triple-A battery is a standard size of dry cell battery commonly used in low-drain portable electronic devices. A triple-A battery is a single cell and measures The positive terminal has a maximum diameter of 3. AAA batteries are most often used in small electronic devices, such as TV remote controls, MP3 players and digital cameras. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the AA battery type.
