Can I use batteries of higher amperage?
To avoid confusion, I would like to add to the first answer that the voltage of the new battery must be the same even though the capacity or amp hours can be increased. In other words, don''t change out your nimh battery with a li-ion which could give you an even higher capacity, but at a much higher voltage. Voltage must stay the same!

Battery power explained
The higher the voltage, the more work the same number of electrons can do. Current = the number of electrons that happen to be passing through any one point of a circuit at a given time. The higher the current, the more work it can do at the same voltage. Power = voltage x current. The higher the power, the quicker the rate at which a battery ...
How is it possible to have high voltage and low current? It seems …
E=IR Your understanding that an increase in voltage should result in an increase in current is correct - swap out a 3v battery in a simple circuit for a 9v and you''ve jumped 3x current as well. High voltage/low current and vice versa is a TRANSFORMATION of what is ALREADY there - you are not swapping a battery (or any voltage source) with ...
When current flows from a battery, does voltage decrease?
Applying Kirchhoff''s current law, you can check it for yourselves. No matter your circuit and its operating conditions, the current going out of the battery should be equal to the current going in. The voltage only changes because the chemicals inside the cell are changed slightly and not because of a change in the number of electrons.
Which One Kills – Current or Voltage and Why? Amps …
