Can I use a 5v charger with a 3.7 V battery?
As we all know, if we use a 5V charger to charge a 3.7V cell, it will make the cell to heat and dangerous.
But in fact you DON’T need a 3.7V charger.
So you can charge your 3.7V battery pack with the 5V charger, but be careful, choose one with the automatic circuit, just like the EasyAcc Power Bank..
Does higher voltage mean longer battery life?
A higher voltage battery has the potential to “push” more current–that is, more electrons–for a given resistance. This translates to the capacity for greater work, which is the same thing as more power. Higher voltage also means less current to do the same amount of work, so longer battery life.
Can I charge a 3.7 V battery with a 4.2 V charger?
1 Answer. 3.7V is the nominal voltage of the cell. As long as the maximum voltage for the cell is 4.2V or higher and the charge current is equal to or less than the amount recommended in the datasheet (usually 0.8C or less is safe) then you can charge the cell with the charger.
Can I use a 3.7 V battery instead of 3.6 V?
There is NO difference between 3.6 and 3.7 volt cells. It is simply a NOMINAL voltage, because every cell needs a reference point. In fact, either 3.6 or 3.7 volt cells have a fairly wide range.
How long do 3.7 V batteries last?
Now a fully charged 1000mAH battery will last approximately 1000mAH/Load current hours. So if the load is 50mA, the battery would last about 1000/50= about 20 hours if fully charged but that is only an approximation.

How many cells are in a 3.7 V battery?
Based on the numbers above, here’s my math: 3.7 / 3.7 = 1. 1800 / 1800 = 1. 1 X 1 = 1 cell.
