If you want to understand a thing said clear, that is about to say there is a order. On the market at present, digital camera battery category mainly have three kinds, respectively is the alkaline battery, nickel metal hydride batteries and lithium batteries. Below small make up to introduce you to the three batteries and their advantages and disadvantages.
1、Alkaline batteries
Alkaline battery is the most commonly used batteries in our life, such as no. 7, no. 5 and 1 type difference, now in general use used digital cameras of the alkaline batteries are 5 alkaline batteries.
Alkaline batteries: the advantages of alkaline battery use convenient, price cheap, optional types and price very much.
Alkaline batteries drawback: cannot be recycled, one-time investment is low, but the cumulative cost is high.
Alkaline batteries use note: if do not use the camera for a long time, should not be placed alkaline batteries in a machine, time is too long, alkaline batteries inside out some corrosive liquid, the liquid if flow into the camera, extremely easy to cause damage of components.
2、Nimh batteries
Nickel metal hydride batteries and hydrogen fuel cells. It is digital camera users on the market at present the most widely used batteries, with alkaline batteries and general, the size of the model is basically the same with alkaline batteries.
Nimh batteries advantages: can charge, generally above hydrogen battery can be recharged 1000 times; Versatility is strong, and there is no compatibility problems, shape size and same alkaline battery, the same can be used to replace each other.
The disadvantage of nimh battery: ma and the voltage of the hydrogen battery durability than alkaline batteries, and one-time investment is alkaline batteries, a lot of counterfeit products on the market.
Nimh batteries use note: nimh batteries need to pay attention, should not be charging time is too long; Use the charger is also very important, if it is found that the battery in high temperature to the hot charging process, should immediately unplug chargers, stop charging.
3、The lithium battery
A new generation of rechargeable batteries, the weight is light, electricity and high, it is the most preferred electronic and digital products mobile power lithium batteries.
The advantages of lithium battery: 30-40% lighter than the other battery, but energy is higher than that of 50-60%; Almost no memory effect, long service life and durability is significantly superior to hydrogen fuel cells.
The disadvantage of lithium battery: the lithium battery's price is very expensive, is one hundred times more alkaline batteries, user investment; And digital camera manufacturers production of lithium batteries cannot be universal, basic if outdoors, it's hard to get a replacement battery run out.
Lithium-ion batteries use note: lithium battery as the first two "substantial", so be careful to prevent not to fall from a height of underground; Other lithium batteries the preservation of the environment should pay attention to moisture, especially during the rainy season in the south.
