What is meant by Battery?

An electrical device that can be charged by an electric device called a battery. An assortment of two or more electrochemical cells makes up a battery.

• The primary battery and
• The secondary battery

are different types of batteries.

The primary batteries are regarded as use-and-throw batteries because they cannot be recharged. The secondary batteries, on the other hand, may always be charged because they are rechargeable.

What exactly is meant by the term “battery life”?

Battery life is the performance metric that is used to determine the longevity of the battery, also known as the lifetime of the battery.

Formula:

Battery life = (Battery Capacity/ Load Current) × 0.7

Battery Life = (Ah rating of Battery / Amp) x Run Time %

Where,

Battery life = in Hours
Battery Capacity = in mAH
Load Current = Consumption of device in Amperes
0.7 = Battery Cycle life considerations – Run Time

Battery life calculation in ideal condition,

Battery life = (Battery Capacity in Ah/ Load Current)  

Where,

Battery life = in Hours
Battery Capacity = in mAH
Load Current = Consumption of device in Amperes
