This is how I'd do it

See if you can find out how by using that function

Yeah, probably late, but:

Code: Lua

1. timer.Create( "BatteryDecreaser", 3, 1, function() battery = battery - 1 end )

I think. my timer is rusty, haven't used it in a while.
The first part is the name (BatteryDecreaser), then how many seconds you want it to wait (1) and then how many times you want it to repeat (3).

If that short way doesn't work use this:

Code: Lua

1. battery = 100
2.  
3. function Battery()
4.     battery = battery - 1
5. end
6.  
7. timer.Create( "BatteryDecreaser", 3, 1, Battery )

Oh, and if the second number value is turned to 0, you'll want to use timer.Destroy (or timer.Remove).

To do this, you can't use a local variable. You wouldn't be able to call it outside of its current state.

Thanks for that reminder, it's updated above, and probably a BIG help to him.
