Run a 9.6 volt Makita drill off 12 volt car battery

The smallest and simplest is a non-rechargeable alkaline 9 volt battery. It will power most LEDs but only for a relatively short time. Most alkaline 9 volt batteries will only provide power to 5 white LEDs (each drawing around 20 ma) for 4 or 5 hours. This time can be extended by increasing the value of the current limiting resistors on the LEDs to 1000 or more ohms. The disadvantage is that

Tips for using LEDs AND some frequently asked questions

Which means, it is safe to switch the LED with 1 kHz, where the LED is on for 0.1 msec and off for 0.9 msecs. Most of the times there is no voltage given for IF(peak), so we can not be sure at what voltage we will reach the 160 mA in the example.
