What is battery capacity?
So, let’s start learning about the very important concept of “Battery Capacity”. Battery Capacity is defined as the product of the electric current flowing in or out of the battery in amperes and the time duration expressed in hours. Battery Capacity influences the time for which a device can operate without using power from any other sources.
How long does a battery take to charge?
The CV stage typically takes 1.5 to 2 hours (depending on termination current% and other factors) so total charge time is about 40m +1.5 hours to 50 minutes +2 hours or typically 2+ to 3 hours overall. But, a very useful % of total charge is reached in 1 hour. Peukert's Law gives you the capacity of the battery in terms of the discharge rate.
