Battery Specifications description, Meaning and with Examples

Because there are so many different types of batteries or (Cells, the basic unit of a battery), my response will be quite general. To generate electricity, cells use a chemical reaction. Most generally, they use two distinct metals that produce a voltage when placed in a container with an electrolyte between them. Some of them are rechargeable, while others aren't. All of them finally die as the metal plates eat away at them. Individual cells are typically connected in series for a greater voltage and in parallel for a higher current in batteries.

They are rated for nominal voltage (number of series cells multiplied by each cell's voltage) and current capacity in Amp/hour. Small batteries are rated in milliAmp/hours, while big batteries are rated in tens or hundreds of amp/hours until they are no longer usable.

1 amp per hour will provide one amp for one hour. A 10 amp/hour battery will provide a current of 1 amp for 10 hours and 2 amps for 5 hours.

In general, monitoring the voltage of each cell or group of cells will give you an approximate estimate of how much charge is left in the battery.

Let's take a look at which batteries I'll need to complete a project. The battery specifications that we need to remember are listed in the table below:

Parameter	Meaning	Example
Voltage Rating	The voltage that a new battery is projected to produce	Alkaline batteries with a voltage of 1.5 volts (e.g. Duracell AA)
Current/Capacity Rating	The maximum current that a battery can deliver in an hour. This is an extremely perplexing specification. Let's say the capacity of a battery is 1500mAh It can deliver 1500mA in an hour, in other words. That isn't exactly correct, though. The manufacturer determines the rating after testing it at various rates. For example, a manufacturer can discharge a battery at 150mA per hour during testing, and if the battery lasts 10 hours, the rating is 1500mAh.	1500mAH means that 1500mA of current can be delivered for one hour.
Discharge Rate	The maximum current a battery can deliver (remember, the current/capacity rating specifies how much capacity is contained in the battery) is shown by this. A battery with a 1C rating can discharge at Capacity times 1.	1C, 2C, and 20C Assume that the battery has a capacity of 1000mAh. A battery with a 1C rating can deliver a maximum current of 1000mA. A battery with a 20C rating can discharge up to 20000mA of current.
Weight	This feature isn't available for every battery type. Most LiPo batteries I've seen have a weight specification, but others don't.	120gms (For a typical 3S1P LiPo cell)
