LiFePO4 Battery Revival with multimeter

简介

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

你所需要的

    • Set your multimeter to diode testing.

    • Make sure your meter is on continuity, and not resistance.

    编辑

    • 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.

    编辑

    • Wait 1 to 2 hours for battery to charge, then put on a charger.
