What type of battery 5 has the longest time in a LED flashlight?
The length of life to see the two indicators is a current through the LED is like a car engine, a battery, or mailbox sizes, this is the most basic, LED current through the smaller life longer, the greater the longer life battery capacity, you say no. five battery one hour no electricity this is normal, and disposable alkaline batteries on the market to sell the flashlight with all can not carry a lithium battery discharge platform is high, the efficiency will be higher, large capacity and endurance, can be multiplied, now the mainstream is the 18650 industrial battery flashlight batteries and CR123 disposable lithium battery, but the latter is not at home commercial batteries, not much high price for people, because can not afford
Flashlight battery life time, mainly depends on the following factors:The size of 1.LED power consumption, which determines the size of the LED flashlight button battery, is certainly used strawhat type LED micro light, low brightness, low power, low power consumption, and 4 batteries of 5 flashlights, should use the high power LED, power consumption may be several times the button battery flashlight. Of course, a short time.2. battery power. The important role of the size of the length of power battery life, power button batteries generally only tens of Ma, and No. 5 battery in general a few hundred Ma, high power Ni MH rechargeable battery, even in the more than two thousand ma. Therefore, the button battery life longer, certainly because LED low brightness, power, small power consumption, not because of the small battery number 5.3. circuit drive current size. The size of the discharge is also very important, if the discharge current is large, then the time is short, the current is small, time is long.Generally speaking, these three factors are the most important. And to more power 5 batteries, or buy a nickel hydrogen rechargeable battery, you can first look at the instructions, the amount of electricity at one thousand or two thousand Ma or more can be.
AA battery flashlight outstanding is small and portable and battery easy to obtain, but if the ratio of luminance and life or 18650 lithium is king, if you use a AA battery flashlight with rechargeable batteries will be much better than the disposable alkaline batteries, disposable alkaline battery nominal capacity of how much, but behind the resistanceincreases drop too fast, can put out the capacity can reach half! Rechargeable battery internal resistance is relatively small, you can relatively large current discharge, it is recommended SANYO eneloop rechargeable battery, you will be satisfied
