What You Need: A fully charged lithium battery (e.g., 18650, 3.7V). A digital multimeter. A load (like a resistor or a small device to drain the battery). Steps:
How do you know if a lithium battery is good?
There are several practical methods to determine the capacity of a lithium battery: Manufacturer's Label: The easiest way is to check the battery label. Most manufacturers print the capacity in mAh or Ah directly on the battery. User Manual: The device's user manual often specifies the recommended battery capacity.
How do you calculate watt-hour rating of a lithium ion battery?
To calculate the watt-hour rating, multiply the battery's voltage (V) by its amp-hour (Ah) capacity. The formula is: Wh = V × Ah. Most common lithium-ion batteries range from 3.7 volts to 48 volts. Therefore, if a battery has a capacity of 10 Ah at 3.7 V, its watt-hour rating would be 37 Wh.
What is the capacity of a lithium ion battery?
A lithium ion battery typically has a capacity measured in watt hours (Wh). Most rechargeable lithium ion batteries have a maximum capacity of 100 Wh. This capacity indicates how much power the battery can deliver over time. The energy density and performance can vary, affecting its limitations in different electronic devices.

How many years can the battery pack last
Your individual driving habits will affect the lifespan of an EV's battery, but most manufacturers cover their battery packs for at least eight years, and anywhere from 10,000 to 100,000 miles.
FAQs about How many years can the battery pack last
How long does a battery pack last?
Battery Pack Lifespan: Due to the consistency issues of battery cells, the lifespan of the battery pack is determined by the worst-performing cell. For NMC packs, this means the cycle life is reduced by 80%, resulting in 1200–1600 cycles. For LFP packs, the reduced cycle life is approximately 3200 cycles.
