The Battery Price Fell for Three Years. The Metal Inside It Tripled.

You have one of these somewhere — in your bag, your car, a drawer. A battery. And for three years straight, the price of what's inside it fell. That sounds like good news. It is the opposite. If you sell anything with a cell in it — tools, electronics, backup power — you have spent three years quoting off that falling price, and so has your customer, and so did whoever built your 2027 model. You are all leaning on a discount. And a discount someone chooses to give you is a discount someone can take back.

Everything else in the chain this year went up. Chips, magnets, medicine — up. The battery went down. That is not the one piece of good luck in a hard year. That is the trap, and I want to show you exactly how it is built, because the same reason the price fell is the reason it can snap back on you with no warning.

Start with the two numbers that should not sit together. A battery pack, global average, cost $139 per kilowatt-hour in 2023. In 2024, $115. In 2025, $108 — a record low. That is BloombergNEF's own survey, not a sales sheet.

Now the number going the other way. The lithium inside those packs bottomed out around $8,100 a tonne in the middle of 2025. By early this year it was running $24,000 to $26,000. As I write this, on the 12th of August, it is about $21.94 a kilo. Call it triple, in a year. So hold both in your head at once: the raw material tripled, and the finished product got cheaper, at the same time. That does not happen by physics. Physics does not discount. A decision does.

A discount always has an address. Somebody paid that difference, and it is worth knowing who, because it tells you how long it lasts. Three things pushed that price down, and every one of them can reverse.

One, the industry quietly switched to a cheaper recipe — the low-cost mix runs about $81 a unit against roughly $128 for the older, richer one, so the average came down without any real cost actually falling. Two, there are simply too many factories, more lines than orders, and they fight on price to keep the lights on. Three, and this is the one that matters, a layer in the middle of the chain has been swallowing the raw-material increase instead of passing it to you. That is the discount you are running on. It lasts exactly as long as they choose to keep swallowing it.

The 7-Factor Supplier Checklist — the checks I run before a deposit moves.

Free. Plus the Monday briefing from Shanghai.

Here is where most people look in the wrong place. When they hear a risk on batteries, they picture a lithium mine and assume the fix is to open one somewhere else. But the tight point is not the mine. It is the middle — the same story as the chips and the medicine I have walked you through all season.

Take the raw powder that becomes the heart of the cell. You can dig the raw material out of the ground almost anywhere — Africa, Canada, South America. But about 99% of that powder gets shipped to one single country to be cooked, refined, and packed into a usable cell, and roughly 93% of the finished material comes out of the same place. The mine is everywhere. The processing is not. You cannot fix that by finding another hole in the ground.

One more thing that catches buyers, and I only felt the full weight of it standing on a factory floor in Shenzhen last week, cells in my hand. The company that puts your brand on the battery usually did not make the cells inside it. A pack assembler buys the cells from a cell maker — often a different company, sometimes a different province — the same way a flashlight brand buys its bulbs.

So when you "check the supplier," you have usually only vetted the easy half, the one who screwed the pack together. The part that actually decides your quality, the part that can catch fire or quietly die in the cold, lives one floor further back, with the maker of the cell. If you do not know that name, you do not really know your battery.

Now the part with a date on it. Last October, batteries and the materials that go inside them went onto an export-control list. A month later the whole package was suspended, for one year. That suspension ends on the 10th of November 2026. A separate measure, covering the raw powder heading specifically to the United States, runs to the 27th of November. Same month as the magnets I told you about two weeks ago. Read the word carefully: these are suspensions, not repeals. The rule did not disappear. It was switched off, and it can be switched back on.

So what happens on those dates? I will be straight with you, the way I always am: nobody knows. Not me, not the two governments, not your supplier. If the pauses hold, nothing changes. If they lapse, the cheapest input in your battery — the one nobody worries about — suddenly needs a licence and a wait. Anyone selling you certainty on that is guessing. My job is not to call the date. It is to make sure that whichever way it breaks, you already know which of your products has a cell in it and where that cell really comes from. The operators who get hurt will not be the ones who guessed wrong. They will be the ones who never checked.

So here is the move — this week, not next quarter. Three steps, and not one of them asks you to predict anything.

One. List every product you sell that has a cell in it. Not just the obvious ones — the power tools, the sensors, the backup power, anything that holds a charge. Most buyers have never seen that list on one sheet, and you cannot protect what you have not counted.

Two. Ask your supplier two questions, in writing: what exact recipe is in the cell, and where is the raw material processed. The first they will answer. The second, almost nobody asks — and the silence tells you how far they can really see into their own chain. That second floor, the cell maker and the test room, is exactly what the Battery Factory Audit App walks you through: the 41 checks I run on the floor before I trust a battery factory, $67.

Three. Take today's price and rebuild your 2027 model at plus 15% and plus 30%. Not a prediction — a stress test, so you know what it does to your margin before someone else decides it for you. Run your real landed number first, free, on the Landed-Cost Calculator.

If you are sourcing solar too, the same discipline is in the Solar Panel Factory Audit App, and all the field tools live here.

You cannot move a battery supply chain from your desk. But before November, you can know exactly which of your products is sitting on one, and what a licence and a wait would do to your number.
