'C'-rating: Capacity is also referred to as the 'C' rating. Some battery suppliers recommend charge
and discharge currents based on the battery 'C' rating. A battery's '1C' current is the same number
as the battery's rated capacity number, but noted in mA or amps. A 600mAh battery has a 1C
current value of 600mA, and a 3C current value of (3 x 600mA) 1800mA or 1.8A. The 1C current
value for a 3200mAh battery would be 3200mA (3.2A).
