This target charge current is relative to the battery capacity ("C"). For standard Li-ion or Li-polymer batteries, chargers often target 0.5C charge current. In other words, if the battery is rated at 500 mA-h, the target current is 250 mA. It is not unusual to charge at 1C (500mA), but this compromises the battery's capacity over time.
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
So for any sensible lifespan you are looking at a useful maximum of around 30mA. Battery capacity is usually a measure of AH capacity and is based on physical size rather than rated voltage. In essence a large battery has greater capacity than a smaller one of the same voltage and hence may be considered as capable of greater current capability.
Charging current for 120Ah Battery = 120 Ah x (10 ÷ 100) = 12 Amperes. But due to some losses, we may take 12-14 Amperes for batteries charging purpose instead of 12 Amps. Related Posts Battery Charging Time: Suppose we took 13 Amp for charging purpose, then, Charging time for 120Ah battery = 120 ÷ 13 = 9.23 Hrs. But this was an ideal case…
I can draw about 5ma out of my wimpy 9v battery and I think your super-duper 9v battery can do no better. If you are talking about a PP3 style battery, the alkaline version has a capacity of around 600mAH. So for any sensible lifespan you are looking at a useful maximum of around 30mA.
The global capacity in Wh is the same for 2 batteries in serie or two batteries in parallel but when we speak in Ah or mAh it could be confusing. - 2 batteries of 1000 mAh,1.5 V in series will have a global voltage of 3V and a current of 1000 mA if they are discharged in one hour.
