Step 2: Size Up The Led

First you want to find how you want to position the LED on the battery holder. Once you know that you can cut one of the leads down to make room. The solder the switch to one of the led leads.

Step 3: Solder It Together

This step involved one part positioning one part soldering. you need to make sure that everything fits together and that none of the leads touch, shorting out your battery. Once you do that, solder the leads to the positive and negative spots on the battery holder. trim any excess leads.

Step 5: Test it Out

Nice one!
One thing I noticed is that it says a CR2020 holder and a CR2032 battery, wouldn't that be a CR2032 holder?

3V lithium batteries never sufficiently light up LED's for me....

that's odd, most leds run at 3v, are you sure your leds are "standard"?
geeklord frenzy5 years ago
I use the LED's that work best on 3.2-3.8 volts and 30 mA. Considering that lithium batteries start out at three volts, it never works out too well. I would much rather use something above three volts with a resistor; I have plenty.
