12 LEDs

I use just 3 good of the Chong battery,(total 3.6 Vs) ordered 12 LEDs for merging, bright in the beginning, very quick slowly dark end was a little bit brighter, why

Electric voltage too Gao?Is the electric current getting bigger?All of 3 batteries is 800 milli- Anne.,

All of batteries are 800 mAses|h of.12 volt led lighting for merging, the electric current is more big and add of possible battery capacity also possible shortage, start to be bright, soon be slowly getting darker, this is very normal

Electricity the quantity Be getting less too much.
The battery of same electric voltage, the amount of electricity of the storage is different.For example our physics tests convenient of rise an electric appliances, the electric voltage comes to a several ten thousand volts, but can't give or get an electric shock dead person.Be should be give or get an electric shock quantity less reason.The length in time of battery usage decides in it store of electricity quantity.
For example milli- Anne of the cellular phone battery|, is the unit that gives or gets an electric shock quantity.The electricity quantity is more many and use time also more many.

First, any while being full of battery isn't a mark to call electric voltage, it will be higher than a mark to call a value, the 3.6 V mark calls of battery's being full of an electricity should attain a 4.2 Vs or so.

Common small power LED has different knot electric voltage, lowest 1.7 Vs, highly and familiarly have 3.6 Vs of.But isn't all 4.2 Vs, so directly order bright give out light a tube,led lighting design actually is once was placed in to flow appearance, if LED not burn have already been getting more unusually lucky very much, certainly the battery consume naturally at this time of very quick.

Calculation once, 12 LEDs, calculate is all mark to call a 3.6 Vs, white LED of 20 mA electric current, that is the 240 mAs and press this electric current to calculate, the battery with 800 mAHs should be able to use 3 hours 20 cent, but this is the theories value and started getting dark no longer than three hours in fact.But this time also not Be getting shorter, calculate super flow appearance, the battery can't consumes "soon gets dark", either.

But, lead flow an usage, will cause white LED tube the Xin function become bad, the main performance is to give out light ability to become bad, say white be get dark.Even if you recovered into normal supply voltage again don't go as well, this is a damage of permanence.You can confirm to use the battery of having the electricity and electricity foot again take a shot, if bright degree wasn't still high, that could prove, otherwise may have bad one section battery at least, can not attain to mark to call of 800 mAH capacity.
