Wattage: high voltage vs high amperage

[stanleysteamer]

This has probably been covered. I'm sorry for (most likely) reposting an old thread. But I can't find it as I'm new to the forum. I'm curious if the same wattage achieved by high voltage or high amperage has an effect on battery life. For example; 20 watts as 6V on a 1.8ohm coil is 3.33A. But 20 watts is also achievable via 2V on a .2ohm coil pulling 10A. Will either drain a battery faster or is wattage wattage and that's all there is to it?

Hope this is the post you were looking for.

Yes, it will have an effect on battery life. The more amps you draw from your battery, the sooner it will need charging

Battery capacity is measured in mAh (milliamp hours). Lets say by way of example that you have a battery that's 2000 mAh, a nice round number. You can draw 2 amps from it continuously for an hour before it's fully drained, or you can draw 4 amps from it for half an hour, or 8 amps for 15 minutes, and so on.

I'm probably not explaining very well, hope that makes sense

EDIT: those links Sthur gave you explain much better than I did

That's the one. Thank you very much.

Thanks for the help. I'm a bit emberassed to say that I didn't know that mAh meant the continuous amps the battery could sustain. Pretty numb considering its exactly in the name. Mili Amp hour. Lol. Sometimes you don know what you don't know I guess.
