Today one of the most popular types of energy replenishment of household appliances are Nickel-cadmium batteries. It is quite simple to operate device, which if handled properly will last a long time. How to treat Nickel-cadmium batteries should be considered in more detail.
Nickel-cadmium battery is designed so that at low internal resistance it can give a sufficiently large current. These batteries will last even a short circuit.
Batteries presented type can withstand prolonged stress. When the temperature of the environment, their performance almost does not change.
Nickel-cadmium batteries are inferior to other types in the tank. However, their highest pay-off makes the battery one of the most popular and in demand in the field of portable equipment.
For appliances with electric motors that consume large currents, the use of such charging devices, such as batteries Nickel-cadmium type, are simply irreplaceable.
Bit currents on which they are used is in the range of 20-40 A. full load for NiCd-batteries is 70 A.
The presented devices have a number of advantages. They are capable of operating over a wide range of discharge and charge currents, as well as temperatures.
Charge batteries Nickel-cadmium type, at low temperatures, due to a high load capacity. They are not picky about the type of a protracted device. This is a significant advantage. It identifies the device from the mass of other varieties, so as to charge the Nickel-cadmium battery can be in any condition. It is resistant to mechanical stress, fire safe. Batteries Nickel-cadmium variety are more than 1000 charge cycles and have the ability to recovery after lowering of capacity.
Low cost together with the listed advantages make the NiCd rechargeable batteries are very popular.
Device Nickel-cadmium battery has a number of shortcomings. The main of them is the “memory effect”. Within a few cycles of charge-discharge modifies the surface structure of the electrodes. In the separator are formed chemical compounds which will later interfere with discharge small currents. This leads to the memorization of incomplete discharge.
Charge Nickel-cadmium batteries the more, the more it will lose its effectiveness. The source will have less capacity.
The disadvantage is also the high-discharge in the first days up to 10% after charging. The downside can be considered the large size.
To understand how to charge nickel-cadmium batteries, it is necessary to take into account a number of features of this process.
Fast charging mode for the power sources rather than slow. Pulsed replenishment capacity is better for them than DC.
It is recommended to restore the device. Required Nickel-cadmium batteries. As to charge them with a similar method, considered the manufacturers of the relevant devices. Reverse charge accelerates the process due to the recombination of the gases released during the vote.
Presented the technique of implementation of the recovery of these batteries allows to increase the service life of up to 15 %. How to charge Nickel-cadmium battery? There is a whole technology. Some users to increase the impact power source is used quick charging with subsequent refueling of the weak currents. This allows you to more tightly fill the battery.
Storage and disposal
Presented to store the battery in a discharged state. There are chargers that have a discharge function. If there is none, before storage Nickel-cadmium batteries drain when using an incandescent lamp with a valid current 3-20 A. the Battery is connected to it and wait until the spiral begins to blush.
This procedure will allow you to store the device for quite a long time. Moreover, the environmental conditions, temperature fluctuations will have no impact on the device.
If you need to dispose of are presented with a variety of batteries, to give them a special point of reception of such devices. In all developed countries they are. This is due to the presence in the accumulator of cadmium. Its toxicity is comparable to the mercury.
Understanding the technology of how to charge the Nickel-cadmium battery, keep it and discard, there is no doubt safety and durability of this power source. It will not harm the environment and human health when the responsible recycling of batteries.
Batteries Nickel-cadmium type are the only kind of such devices which need restoration.
Periodic cycle discharge-a charge will increase the life of the batteries. It should not be done too often, but from time to time it is necessary.
For restoration there are two types of devices. The first is called reverse pulse battery charger with different time duration. This is a very effective device, but complex and expensive. Restoration of Nickel-cadmium batteries can perform more simple device. It makes the cycle of charge-discharge automatically. Such a device is cheaper, more convenient and allows you to charge 2-4 batteries at once.
To initiate the process you must insert the batteries in the cassette equipment. Using the switch, specifies the number of batteries. The inclusion of the device in the network will trigger the indicator. The color red represents charging, yellow discharge. The green light indicator alerts termination of the process. Discharged batteries should be enforced. For this purpose, the device has to be switched a certain lever. After discharge the device continues the charging process automatically.
After reviewing the main characteristics of such a power source, such as Nickel-cadmium batteries, it is possible to exploit them. Adhering to the manufacturer's instructions, regularly repairing the batteries can greatly extend their lifespan. Correctly utilizing of the presented device, just to protect themselves, other people and the environment as a whole against the toxic effects of cadmium.
