Safety is obviously important when dealing with fire, but you’re also dealing with electrical charges and batteries, which contain dangerous ingredients.  Wear gloves. Although there aren’t many safety measures available in prison to make the infamous lighter from “Orange Is the New Black,” you’ll want to take safety precautions and protect your hands. Keep a fire extinguisher and garbage receptacle ready. If you need to dispose of batteries, be sure to recycle them. Some municipalities and states, like California, require batteries to be recycled, and your community might have battery collection procedures. Dispose of the battery immediately if it starts to leak. This could be battery acid, which is dangerous and corrosive. You don’t want a leaky battery.  Plus, you’ll need a charge to generate the flame. Most batteries will work, but a AA alkaline battery is common for this type of lighter and a good size. Use two batteries if possible, or a single 9 volt, because one AA battery might not provide enough power. This type of flame will start quickly and burn out quickly. So, have a flammable source on hand to transfer the fire, if you want to keep the flame going.  Sheets of loose paper, newspaper, or dry leaves will work well here. It is important to transfer the fire and not let the battery itself light on fire, since it could explode. On most batteries, this should be clearly marked. On a AA battery and other cylindrical batteries, the positive (+) end or terminal—known as the cathode—has a small convex bump, while the negative (-) end or terminal—known as the anode—has the inverse: a small concave indent into which the bump can fit.

Summary:
Take safety precautions. Use new batteries. Prepare a transfer source. Find the positive and negative ends of the battery.
