Understanding Lithium-Ion Battery Parameters
Working with 3.7 V lithium-ion batteries means we must know certain key features. These features help us understand the battery’s capabilities. Let’s look at these important factors closely.
Battery Capacity (Ah)
The battery’s capacity tells us how much energy it can hold and use. Measured in ampere-hours (Ah), a bigger number means more power for longer. This is great for things that need power all the time.
Voltage (V)
Voltage is the power difference between the battery’s ends. For 3.7 V lithium-ion batteries, it shows how much power it can send to a device. It’s key to make sure the battery and device can work well together.
Maximum Charge/Discharge Current (A)
This shows the most power the battery can give at once. Measured in amperes (A), it hints at how good the battery is for devices using a lot of power. Or for quickly charging your battery.
Cycle Life
Cycle life tells us how many times a battery can be charged and used before it loses too much power. Knowing this is important for long-term battery use. A longer life means you won’t need to replace it as often.
Self-Discharge Rate
The self-discharge rate is how fast the battery loses power when not being used. A low rate means the battery stays charged longer while waiting to be used. This is important for batteries we don’t use every day.
| Parameter | Definition | Unit of Measurement |
|---|---|---|
| Battery Capacity | Energy storage and discharge capability | Ampere-hours (Ah) |
| Voltage | Potential difference between terminals | Volts (V) |
| Maximum Charge/Discharge Current | Maximum continuous current supply | Amperes (A) |
| Cycle Life | Number of charge and discharge cycles | N/A |
| Self-Discharge Rate | Rate of discharge when not in use | N/A |
