Battery Power Capability (C) Answered
I'm trying to understand a little bit more about batteries. I've learnt so far:
"Volts, amps, and watts measure electricity. Volts measure the “pressure” under which electricity flows. Amps measure the amount of electric current. Watts measure the amount of work done by a certain amount of current at a certain pressure or voltage."
Now I'm interested in knowing the maximum amount of energy you can draw from a battery at any one time.
I presume you can't instantly drain a batteries full energy capacity at any one time. I have read that:
"The way the power capability is measured is in C's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely. Lead acid batteries can have very high C values (10C or higher) , and lithium coin cells have very low ones (0.01C)"
Am I write in saying a 1.2V 1200mAh has a power capability of 1.2C? In which case I should only ever draw 1.2C or less to preserve the battery?
How do I increase this amount when using 2 batteries, if I wire two batteries together does the power capability increase to 2.4C for the above example batteries? If so do I have to wire them in parallel or series for this to work?
