The possibility of multiple charging makes various kinds of batteries more attractive in terms of improving the operational properties of electrical equipment, in comparison with conventional galvanic cells.
The number of such periods for batteries manufactured by various technologies is significantly different. This article will talk about how many times you can charge lithium, cadmium, and metal hydride batteries.
Li-ion
Lithium-ion batteries are one of the most common rechargeable batteries. Such products are used in various household devices and gadgets, and can also be produced in the form of batteries of standard sizes.
What devices is used
Li-ion batteries can be found in the following devices:
- Laptops.
- Cameras
- Electric cars.
- Kids toys.
- Macbook Air and Pro.
- Android Phones.
- Smartphones Iphone.
- Electric bicycles and scooters.
- Such products have the original form or can be released in the form of conventional batteries.
The number of charge-discharge cycles
The standard number of charge cycles of a lithium technology battery, such as a cell 18650is about eight hundred.
High-quality products can recharge more than 1000 times, but at the end of the operational period, a noticeable decrease in capacity can be observed.
How to reach the maximum number of cycles
In order not to "kill" the battery, a deep discharge of this type of battery is completely prohibited. To maximize the life of such a battery, it must be operated in appropriate temperature conditions (from -20 to + 50 ° C).
The use of chargers in which the rated current is exceeded is also unacceptable. In this case, the battery overheats and begins to degrade.
Li-Pol
Lithium polymer batteries are advanced lithium batteries, so there are not many differences between the two types of cells.
What devices is used
Li-Pol batteries can be used in various phones with the Android operating system, as well as in other communication devices. Such a battery is suitable for radio-controlled toys, especially for flying models.
In this case, low weight and the ability to give high current are the undeniable advantages of using this type of battery.
The number of charge-discharge cycles
Usually, lithium polymer batteries capable of withstanding up to 900 recharge cycles. Of course, the maximum amount depends on the quality of the battery, but negative operating conditions can significantly reduce the battery life.
How to reach the maximum number of cycles
A deep discharge will unambiguously lead to a battery failure, therefore, in various gadgets the batteries are equipped with a special controller that stops supplying current to the contacts at a certain discharge level.
Significant deterioration of lithium-polymer products is also possible at inappropriate storage or operating temperatures (the optimal value of this parameter is +20, but operation is possible from -20 to +40 degrees Celsius). The battery must also be properly mothballed.For this purpose, a new product undergoes several charge-discharge cycles.
Ni-mh
Nickel-metal hydride batteries also withstand a large number of charge-discharge cycles.
What devices is used
Ni-Mh batteries can be successfully used in the following areas:
- Space industry.
- Radio equipment.
- Uninterruptible power supplies.
- Equipment with electric drive.
Wide distribution Ni-Mh batteries received in sizes (AA, AAA, Crohn, etc.)
The number of charge-discharge cycles
The actual frequency of the charge-discharge for the entire service life is at least five hundred. Many manufacturers indicate up to 1000 cycles, but in practice this figure is not always true.
You can achieve good results if you carefully adhere to the basic rules of storage and operation of such products.
How to reach the maximum number of cycles
In order to achieve maximum runtime of nickel-metal hydride batteries, it is necessary to periodically perform the training procedure for the current source.
For this purpose, it is sufficient to completely discharge the battery at least once a month and then set it to charge until it reaches 100% level.
Ni-cd
Nickel-cadmium batteries are already obsolete products, but due to their cheapness, they are still actively used in various electrical engineering.
What devices is used
Small power supplies of this type can be made in the form of conventional finger batteries. Also, in various power tools, such a battery can be used as part of a battery, the regulation of the supply of electric current in which is carried out by the controller board.
Most often, such a scheme can be found in screwdrivers and other small-sized power tools.
The number of charge-discharge cycles
The nickel-cadmium battery is rated for 100 to 900 charge discharge cycles. With the daily use of modern products, the health reserve is enough for about 1 year.
Of course, the operating time of the device will also depend on the operating conditions.
How to reach the maximum number of cycles
The aging of nickel-cadmium batteries is mainly due to the memory effect. For this reason, it is recommended to determine the level of charge of the elements before connecting the memory.
If this procedure is carried out before the incomplete consumption of electricity, the next battery discharge will carry out to this capacity value.
If a non-original charger is used, it is recommended to check the current and voltage levels with a multimeter. Deviation of these parameters can also lead to premature failure of the battery.
