Dear Experts
I bought a lithium-ion battery rated at 3.7v.
I charge it with my existing phone charger rated for 3.7v batteries and charging at 4.2V.
i like to know why are batteries are rated like this. That is, a 3.7V rated battery is actually charged to 4.1 or 4.2 when its considered 100% fully charged. So, why is it not rated at 4.2v?
Why the misrepresentation? Of course, I am assuming there is misrepresentation.
And yes, I understand that you need a higher voltage to charge to a voltage that is near but lower than that voltage. So my question is on the choice of the rating and not the reason for using higher voltage to charge a battery rated lower.
Thank you for reading.
Best regards
Pascal
