First, check your battery. And make sure that you have connectors with which you’ll connect your new batteries. Next, find the batteries from which you are going to draw your charge. Do check that they are already charged.

Now check the voltage of your drill battery. Make sure that you have enough batteries to charge your drill battery to the correct voltage.

To make the calculations easy for you, we have an example-
Suppose your cordless drill battery is 12V. Then you will need 8x AA batteries of 1.5V each to be connected in series to give a total of 12V.
Gather these batteries with some pliers, tape, and two pieces of wire.
Now comes connecting them in series connection. Here are the steps:

  1. First, find out the positive and negative sides of each battery and connect the positive of one with the negative of others through connecting wires.
  2. Secure the connections with the electric tape.
  3. Perform steps 1 and 2 with all 8 batteries.
  4. Bend these batteries in U shape.
  5. Then connect the positive side of this series to the positive side of the drill battery and the negative side with the negative one.
    Keep this arrangement as-it-is for around 2 hours and your batteries will charge like before. Although keep and disconnect everything alert in case you smell anything funny.
