Step 2: Check your battery

Charge up your battery up for a few hours or overnight to make sure that it is charged. If you suspect your charger isn’t working you can trickle-charge it from a different voltage source. To make sure you don’t overcharge it put some little lightbulbs from christmas lights in series so the current is below 1 amp. I use 1/2 amp usually.

When you’re sure your battery has had a fair chance to charge, check the voltage with your multimeter. Since you’re reading this, the voltage is probably a lot lower than the label says it should be.

To see how much current your battery can put out, run the drill. Grab the chuck and stall it to get a feel for how much power it has.
