How to check the capacity of an 18650 lithium battery

Introduction How to check the capacity of 18650 lithium battery? You can get the battery capacity by charging or discharging. If you search for “USB voltage display” online, you can see the corresponding products.

How to check the capacity of an 18650 lithium battery

Battery capacity can be obtained by charging or dischargingIf you search for “USB voltage display” online, you will see matching products. Choose one with a display. products with capacity (available in grades above 20), you can first discharge the battery to a voltage of 3.5V, and then use the charger to charge.

Precautions for using 18650 lithium battery

Usage correct lithium 18650 battery Do not combine with original batteries (such as dry batteries) or other batteries of different capacities, types or brands, and do not use batteries that have odor, generate heat , are discolored or distorted, or are abnormal in any way. If the battery is in use or charging, remove it from the device or charger and stop immediment to use it.

As follows:

1. False capacity:

At present, China's 18650 battery technology has a capacity of 2200, and many sellers have reduced the capacity in order to attract consumers. The battery is falsely labeled with a capacity of 3000 or 3200, etc. to deceive consumers and obtain more benefits.

2. Reconditioned Batteries:

Reconditioned batteries come from disassembled foreign batteries, obtained through some illegal channels, and then reconditioned and marked with fake capacity. These batteries are very dangerous for consumers. This involves carrying a timed explosive with you, and consumers are asked to keep their eyes peeled for consumption.

3. Copycat Battery:

I think everyone knows the word copycat. Lithium battery is a type of battery that uses lithium metal or lithium alloy as the battery material.negative electrode. a non-aqueous electrolyte. In solution batteries, the chemical properties of lithium metal are very active, making the processing, storage and use of lithium metal very demanding on the environment. Manufacturers of counterfeit batteries may completely ignore these requirements, which can lead to danger at any time.

Consumers should pay attention to the above conditions when purchasing LED flashlights. Buying from a regular manufacturer of powerful flashlights is guaranteed.
