Free Shipping on Domestic Orders $75+

Introduction

I currently don't have a LiFePO4 Battery charger, so this is a tutorial for how to charge one with your multimeter.

What you need

1. Step 1 Getting the multimeter ready
  Set your multimeter to diode testing.
  
  Make sure your meter is on continuity, and not resistance.

3. Step 2 Attach multimeter leads to battery
  Make sure the polarity is not reversed, or damage can occur to the battery.
  
  Make sure your multimeter battery is a 9v, otherwise button cells will drain quickly.
