The Battery on Her Lap
By Lars Olson

A man set a cordless drill battery on my counter this morning and asked if I had the same one in stock. I did. But I looked at the one he brought in first.

The pack was fat. Not cracked, not scorched. Fat. The flat black case had begun to bulge at the seam, the way a can does when something inside it has gone wrong. He had not noticed. Most people do not. He told me it still worked. He was right. It did still work, and it was also a small fire waiting for a reason.

I have sold a great many batteries from behind this counter. The lithium ones came in slowly, then all at once. They are in the drill. They are in the leaf blower. They are in the doorbell camera, the headlamp, and the little silver pack a man keeps in his truck to jump a dead car. They are the most powerful thing most people own, and they are the thing most people respect the least.

I told him to leave the swollen one with me. He shrugged. It is just a battery, he said.

It is not just a battery. A lithium cell holds a remarkable amount of energy in a very small space, which is the whole point of it, and which is also the danger of it. When a cell is healthy, the energy comes out slowly, on your terms, through the two posts on the end. When a cell is damaged — dropped, punctured, charged too hard, worn thin — the energy gives it all back at once. Engineers have a calm name for it. They call it thermal runaway. There is nothing calm about it. The cell swells, vents, and then it does not stop getting hotter, because it is feeding itself.

The swelling is the warning. The fat pack on my counter was the part of the failure a person can still see.

In April, the federal product safety commission reissued a recall for a wireless phone charger, a small, flat power pack you press to the back of a phone. The model is the Casely Power Pod, E33A. They had recalled it once already. They had to do it again because people kept getting hurt.

One of them was a woman in New Jersey. She was seventy-five. She was charging her phone with the pack resting on her lap, the way any of us would, the way it was built to be used. It caught fire and exploded. She was badly burned, and she later died of those burns.

I keep coming back to the lap. Not a warehouse. Not a charging station. A lap, in a chair, at home. The most dangerous object in the room was the smallest one, and it was touching her.

I am not telling you to be afraid of your tools. I sell the tools. I use them. A good lithium pack, treated with sense, will give you years and never once raise its voice. I am telling you the energy is real, and the respect is cheap, and most people are spending neither.

So here is the sense. Charge these things where you can see them, on a hard surface, away from the bed, the sofa, the pile of rags in the garage. Do not charge them through the night while you sleep on the far side of a closed door. Use the charger built for the pack, not the cheapest one on the shelf, picked because it fits. If a battery gets too hot to hold, stop. And if a pack has gone fat, if the case has begun to swell the way the drill battery swelled, it is already telling you what it plans to do.

The swollen one does not go back in the drawer. It does not go in the kitchen trash, either, where it can finish the job in the truck or the landfill. It goes to the hazardous-waste drop, today, while you are still the one deciding when it comes apart.

The man took my advice and left the fat one on the counter. Go look at the one charging in your house tonight.
