Original Description (Battery Holder)
An easy way to bring power to your 3 Volt LEDs.
This fully assembled unit features
- a coin cell holder made for the common cr2032 battery
- wire leads
- a convenient push-on push-off button switch to turn your LEDs on and off
Add some cr2032 batteries to your order along with the coin cell holder and you will be ready to run as soon as this package arrives. You can find more cr2032 batteries at local stores.
In our tests, the premium CR 2032 coin cell we ship with our coin cell holder is 200mA and can easily run 1-10 LEDs safely and brightly.
***Solid LEDs need to be separate from any flash or flicker LEDs. Give flash or flicker groups their own coin cell.*** This is not an issue with any of our other power supplies. You can mix solids with flash/flicker using our 3 Volt AAA holder or 3 Volt AA holder or 3 Volt wall adapter.
In our tests, 6 lights lasted over 12 hours on one battery. By 12 hours they were noticeably dimmer. A test of the battery at 12 hours showed the voltage was down from 3.0 to 2.6 volts. The lights continued to stay on at a nice level for several additional hours before another battery was needed. This CR2032 battery holder will run your lights for a nice long time.
How we connect lights to this unit:
The 3V coin cell battery slips right into this holder. And the LEDs are connected red wire to red wire. Connect the black or green wire to the black wire on the battery holder. Remember to protect connections with tape or use our shrink tube or your own, or use tape to keep the connections separate.
- We have 2 wire lengths on the coin cell holder:
- The 8" coin cell holder has 4" red wire on either side of the black switch and 8" black wire
- The 4" coin cell holder has 2" wire on either side of the switch and 4" black wire. Either Coin cell holder comes with a black switch.
Holder/Switch Dimensions:
The coin cell holder is .24 inches thick and .9 inches across at the widest point. You can clip the plastic "wings" to save 0.1 inch on the width if space is at a premium!
