Amara Raja Power Systems Associate Engineer Interview Questions and Answers

Charging batteries last longer than disposable batteries.

• Charging batteries can be recharged multiple times, extending their lifespan.

• Disposable batteries are meant for single use and need to be replaced once depleted.

• Examples of charging batteries include lithium-ion batteries used in smartphones and laptops.

• Examples of disposable batteries include alkaline batteries commonly used in remote controls.

The battery life time may be short due to various factors such as usage patterns, age of the battery, and environmental conditions.

• Battery life can be affected by the frequency and intensity of usage.

• Older batteries tend to have shorter life spans.

• Extreme temperatures can also impact battery life.

• Certain apps or settings on the device may drain the battery faster.

• Regularly updating software can optimize battery perform...read more

Lithium-ion batteries commonly use lithium, cobalt, nickel, and graphite as key chemicals.
