How much power will the battery pack lose

Why do lithium ion batteries lose capacity?

You experience capacity loss in lithium-ion batteries due to internal chemical changes during the battery aging process. Electrochemical models show SEI layer growth, lithium plating, and electrode degradation drive capacity fade and shorten battery life.

Why do unused batteries lose power?

Even unused batteries gradually lose power due to chemical reactions inside them. In fact, alkaline batteries can lose 5-20% of their charge per year just sitting on a shelf. Lithium batteries fare better but still degrade. Why does this happen, and how can you stop it?

Why do EV batteries lose power?

At the core of every EV is a lithium-ion battery —a high-performance energy storage system that powers everything from acceleration to climate control. However, these advanced batteries gradually lose capacity and efficiency due to various chemical, thermal, and mechanical stresses.

How long does a new battery last?

You might assume that a brand-new battery, sealed in its original packaging, stays fully charged forever— but that’s a myth. Even unused batteries gradually lose power due to chemical reactions inside them. In fact, alkaline batteries can lose 5-20% of their charge per year just sitting on a shelf. Lithium batteries fare better but still degrade.
