About Us

Welcome to EV Battery.

My name is Sherjeel Sajid, and I have over 15 years of hands-on experience in the battery industry, working with both EV batteries and traditional car batteries.

I created this website to share my knowledge and make battery topics simple, practical, and easy to understand for everyone.

My Experience with Batteries

Over the past 15 years, I have worked directly with different types of automotive batteries, including:

  • Lithium-ion EV batteries are used in electric vehicles
  • Lead-acid car batteries are used in petrol and diesel vehicles
  • Battery testing, charging, and performance analysis
  • Real-world battery failures and maintenance issues
  • Effects of heat, load, and usage on battery lifespan

Through this experience, I have learned how batteries behave in real-life conditions, not just in theory.
