Can you properly charge the battery?

Laptops, cameras or smart phones need to be constantly available. Without access to electricity we used only by charging the battery.

To have your device at the ready, it is important to adhere to the principles for proper charging. However, in recent charging Li-poly batteries have to follow different rules than the obsolete Ni-Mh batteries. We will tell you how different kinds of charge, in order not to lose capacity and have the longest life.

Ni-Mh batteries suffer from memory effect

Nickel-metal hydride batteries were classic 90 20th century. Especially in the form of rechargeable AA batteries. Ni-Mh batteries can still be found in some older devices such as older laptops, camcorders and cordless tools. For this type of battery is a typical memory effect, which is designed by charging the battery when it is not yet wholly exhausted or Not charging it to a state of full charge. The capacity of the damaged memory effect can be partially restored formatting battery. "Format battery performed so let the battery fully discharge and then fully charge. Formatting is performed at least twice or three times in a row. In the case of Ni-Mh batteries repeat it at least once every three months to alleviate the capacity reductions, "said Radim Tlapak the company NTB CZ, distributor of batteries T6 power.

Ni-Cd batteries are already obsolete

Nickel-cadmium batteries can be found only in the really old types of cameras or camcorders. It is widely used also in mobile phones, but is gradually replaced by more efficient types of batteries. The shop is still found in the form of rechargeable AA batteries. The average charging time is from 45 minutes to two hours, but the capacity of the battery is compared with the newer kinds lower. A great disadvantage is the memory effect, which is Ni-Cd battery becomes most noticeable. It is because of the memory effect must be recharged only when they are fully discharged. Once a month is necessary to perform formatting. When charging the battery may remain in the charger for more than 24 hours, since there would be excessive overcharging. When the overcharge is experiencing excessive heating and consequent loss of capacity.

Li-ion leave deep discharge

Lithium-ion batteries are currently the most widely used type of battery. They can be found in almost all modern appliances. The Li-ion batteries until recently thought that unlike older types of batteries have no memory effect. Scientists, however, in the spring of this year managed this long existing dogma to refute. In laboratory conditions for Li-ion battery memory effect actually showed, the effect is negligible. This finding certainly does not mean that the Li-ion batteries should be deeply discharged and recharged.

"Li-ion batteries may discharge during normal use, only partially. Full battery can discharge these modern batteries even be harmful, "said Radim Tlapak of NTB CZ company." In the result can indeed lead to faster reduction in capacity and extending the charge, "said Tlapak. Against harmful deep discharge and overcharge the battery protects the sensors should avoid reaching an extreme condition.

Li-poly batteries can be recharged at any stage discharge

Lithium-polymer batteries are the most advanced of all these species. They can be described as an improved version of the Li-ion battery, which contains liquid but gel electrolyte. With gel batteries are Li-Pol very thin and appear in different shapes. Due to the higher cost are not yet mass-extended. Today we find especially in modern high-end devices, such as iPods, iPhones, iPads, netbooks and ultra-mobile laptops. Battery Li-pol is not necessary prior to use to format the memory effect is they almost completely suppressed. These batteries are sensitive to the exact charge, so u Li-Pol battery Only use chargers that are supplied. Compared with other types of batteries are Li-pol battery only very low self-discharge, which means that the period of non-spontaneously lose capacity.
