If a battery has 1C rating then the battery has a capability of delivering 1A of current. So, a battery with 10000 mAh of capacity will have a C rating of 10 C which means the battery has a capability of delivering 10 A of current at a constant voltage (fixed voltage/rated voltage). Theoretically, it is calculated as A-h divided by 1 hour.Įxample: Let’s consider a battery which has 10000 mAh of power capacity.Īfter dividing 10000 mA hour/1 hour gives 10000 mA = 10 A = 10 C It means the amount of current that the battery can deliver. Though the theoretical calculations seem ideal but the battery’s duration changes based on the temperature and the current consumption etc. It is the energy stored in a battery which is measured in Watt-hour We can’t just keep on using voltage and current alone to explain about a battery’s functionality, there are some unique terms that defines the characteristics of a battery like Watt-hour (mAh), C-rating, nominal voltage, charging voltage, charging current, discharging current, cut off voltage, shelf life, cycle life are the few terms used to define a batteries performance. Technical terms used while dealing with batteries

That is the reason DC is preferred for portable electronic devices.

Even the losses due to AC power are more when compared to the DC power. Now Why DC is preferred over AC? In most of the portable electronics, AC can’t be stored where as DC can be stored without any difficulty.

Batteries are arranged in series to increase the voltage and in parallel to increase the current. If we ever see the inside of a power bank we can find set of batteries arranged serially/parallel based on the requirement. The best known example for a battery is a power bank which is used to charge up smart phones. For example if we take cells that we use in watches or remote controls, it can give maximum of 1.5 – 3V.īattery: The functionality of the battery is exactly same as that of a cell but a battery is a pack of cells arranged is a series/parallel fashion so that the voltage can be raised to desired levels.

Also let’s find out why we exactly need a battery and why can’t we use the Alternating power (i.e., AC power from the wall sockets) instead of DC power.Ĭell: A cell is an energy source which can deliver only DC voltage and current which are in very small quantities. Let’s see the basic difference between a battery and a cell. Today in this tutorial we discuss briefly about various types of batteries, their classification, terminology and specifications. Can you imagine the situation without these energy sources? We wouldn’t be able to build any wireless electronic device and have to rely on wired power source only, even electric cars and space missions would not be possible without Batteries. Battery is the primary power source for any electronics wireless gadget, be it a smartphone, laptop, watch or remote.
