Types and models of lithium batteries

Introduction Types and Models of Lithium Batteries 1. 10440 Battery The 10440 battery is a lithium-ion battery with a diameter of 10mm and a height of 44mm. It is often called an AA battery.

Types and models of lithium batteries

1. 10440 Battery

The 10440 battery is a lithium-ion battery with a diameter of 10 mm and a height of 44 mm. It is the same size as what is often called an AA battery. is generally very small, only a few hundred mAh, mainly used in mini electronic products. Such as flashlights, mini speakers, amplifiers, etc.

2. 14500 Battery

The 14500 battery is a lithium-ion battery with a diameter of 14 mm and a height of 50 mm. It's also the size of what we've always called AA. Batteries. This type of battery is generally 3.7V or 3.2V. The rated capacity is relatively small, a little larger than the 10440 battery, generally 1600mAh, and has excellent discharge performance. The most important areas of application are consumer electronics. wireless speakers, electric toys, digital cameras, etc.

3. Battery 16340

The 16340 battery is a lithium-ion battery with a diameter of 16mm and a height of 34mm. This battery is shorter in height and its capacity is not very large. small, so it often appears in bright flashlights, LED flashlights, headlights, laser lights, lighting fixtures, etc.

The model and battery type of the electric vehicle are not provided, so the precise price of battery replacement cannot be given.

When the following conditions occur in the electric vehicle battery (we are talking about lead-acid batteries here), it is a sign that the battery is about to be scrapped:

p>

1 The actual discharge capacity of the battery is less than the nominal capacity. About 60% of the capacity cannot be significantly increased after maintenance and it can be determined to be scrapped. Indeed, when using the battery, the performances will be significantly attenuated after the capacity decreases to about 60%, and all components have basically reached a state of deterioration. This degradation has a tendency to gradually accelerate, and soon the charging and discharging. will be completely lost.

2. The battery cannot be charged. If you feel that the electric car battery is not charging, first check whether the connection of the charging circuit is reliable, check whether the connection and plug are in good condition, carefully check whether the socket and plug have an “ignition” arc. burning phenomenon and no broken wires are damaged, etc.

If there is no problem, check whether the charger is damaged and whether the charging parameters meet national standards. If there is no problem, the battery may be damaged. If the situation does not improve after repair, you should replace the battery with a new one.

3. The battery isgenerates significant heat when charging. Due to the battery life, the anode will soften significantly (the main failure mode), the active material will fall, the internal resistance will increase, and the plate impurity elements will continue to precipitate, so when the Charge gas exhaust rate increases, efficiency deteriorates, and heating capacity increases.

At this point, if you open the battery safety valve for inspection, you will see that the electrolyte is "black" and serious defects cannot be repaired. At this point, the battery discharges very quickly and sometimes runs out of power shortly after charging.

4. Batteries that have reached the end of their service life will experience a significant drop in performance and extremely unstable performance, which may lead to adverse consequences: such as deformation due to extreme heat.nerated during charging, a short circuit, an opening. circuit, or even a breakdown. Risk of explosion. Therefore, when the battery reaches the end of its service life, it should be replaced with a new battery in time.
