Everything About Battery !

ব্যাটারি সমাচার!  

চার্জার সমাচার!

কতক্ষন চলবে জ্বলবে সমাচার 😁!

Battery : 5000mAh 

So you should need 15-25%(min) current supply for charging

( current: you shouldn’t take much because the higher current is never good for Battery health, maximum current for GEL type is 50% and AGM type 30% )

Consider 20% current supply for our charger.

Charger should be: 1000mA, 5v

( voltage shouldn’t be more than 30-40% than the Battery for Lithium-ION and not more than 15% for LED acid Battery and others like led acid type ) 

>>Now it will take :5000mAh/1000mA = 5 hours  to full the battery.

Now again considering charging loss up to max 40% 

So battery new rating to charge : 5000+ 5000*40% = 7000mAh 

>>So charging time will be: 7000/1000= 7 hours

-------------------------

Here I am considering a 3.7v 5000mAh mobile battery, using a charger of 5v, 1000mA outputs 

Example 2: 

So 12v 12Ah  led acid battery needs a transfer of  240/16, 2A 

 Why this is because this type of transformer is available in the market.

Now reduce the voltage to 13.8v using your own circuit using Resistor and IC (78xx) and 2A should be dropped by 0.2A to get 1.8A :) 

Which will took: 12Ah/1.8A = 10 hours for a full charge. Ok??

With loss :16.8Ah/1.2A =14 hours 

-------------------------

Now come to the next point 

::Uses:: 

If your battery rating is 5000mAh 

And you are using a led strip having 10 SMD led (0.5W 2850 SMD LED

) which are in parallel

and 

each one SMD takes 150mA then total current consumption till the reduction of battery from 3.6v to 2.8v (forward voltage for led) will be 150*10= 1500mA 

Then 5000mAh/1500mA=3.33 hours

So your led strip will be alive for 3 Hours for one full charge. 

( by this you can calculate anything, how much it will be alive) 

You can get specifications from the internet,  this could give you an idea about Battery handling 🙂
