What is the difference between a lithium battery and a Ni MH battery?
1.The difference between a Ni MH battery and a lithium battery -- volume
Rechargeable lithium battery is widely used in many new mobile devices because of its small size (relative), light weight, low self discharge rate and no memory effect compared with the common Ni Cd / Ni MH battery. The batteries that we normally use for mobile phones, laptops, PDA and other mobile devices have gradually been replaced by lithium batteries. The memory effect of Ni MH battery is not obvious, there is one point, to push, do not have to put the photo after filling, usually use is the best light after sufficient.
2.The difference between a Ni MH battery and a lithium battery -- electricity
The lithium battery has a large energy ratio and a small battery; the voltage of a single lithium battery is 3 times that of a Ni MH battery; without memory effect, it can be filled with the battery. But it can not be used to charge, such a charge and discharge too many times, it will affect the life of the battery. Lithium batteries should not be stored for a long time, and a permanent loss of capacity will be permanent for a long time. It is better to charge 40% after charging and store it in the refrigerator box.
3.The difference between Ni MH battery and lithium battery -- charging method
The charge requirement of a lithium battery is different from the nickel cadmium / nickel hydrogen battery, and the charged lithium battery monomer voltage is 3.6V (some cells may be called 3.7V). With full power, the voltage of the battery will gradually increase, which is the indication of lithium battery is full of the general recommendation to stop charging voltage of 4.2V manufacturers (single battery case). For lithium battery, the current limit method is generally limited. If a friend wants to charge the lithium battery independently, it should be noted that the charging method is different from that of Ni Cd / Ni MH battery, and can not use the common charger of Ni Cd / Ni MH battery.
