6 FAQs about [Lithium battery voltage drops quickly]

What happens if a lithium ion battery drops?

2. Rapid Voltage Drop When a lithium-ion battery starts to decline, it often experiences rapid voltage drops under load. This means that when you use your device for resource-intensive tasks, such as gaming or streaming videos, the battery voltage might plummet suddenly, causing the device to shut down or lose power unexpectedly.

What happens when a lithium ion battery discharges?

When the lithium-ion battery discharges, its working voltage always changes constantly with the continuation of time. The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve.

What happens when a lithium ion battery is aging?

When the lithium ion battery is aging, the change of K value (voltage drop) is the formation and stability process of the SEI film on the surface of the electrode material. If the voltage drop is too large, there is a micro-short circuit inside, and the battery is judged to be unqualified.
