Personal battery — Factorio Production Calculator
Personal battery is crafted in the assembling machine in 10 seconds, producing 1 per craft from 5 × Battery, 10 × Steel plate. At 60 per minute you need 20 assembling machines, and the chain behind it draws on 4 raw resources: water, petroleum gas, iron ore, copper ore.
Production chain for 60 Personal battery / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Sulfuric acid | 6,000 | 2 | Chemical plant |
| Iron plate | 3,420 | 182.4 | Furnace |
| Sulfur | 600 | 5 | Chemical plant |
| Steel plate | 600 | 160 | Furnace |
| Battery | 300 | 20 | Chemical plant |
| Copper plate | 300 | 16 | Furnace |
| Personal battery | 60 | 20 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Water | 21,000 |
| Petroleum gas | 9,000 |
| Iron ore | 3,420 |
| Copper ore | 300 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Personal battery recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 1 | Battery × 5, Steel plate × 10 |
What the whole chain needs
60 personal batterys per minute pulls in 6 intermediate products, and the whole tree comes to 405 machines across 3 machine types, fed by 4 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 21,000 per minute, which is 23.33 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses personal battery
1 base-game recipe consumes personal battery, sorted by how much each one takes:

- Battery — 5 per craft
- Steel plate — 10 per craft
FAQ
How many assembling machines do I need for 60 personal batterys per minute?
20 assembling machines. One at standard speed produces 3 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does personal battery take?
At 60/min the chain consumes 21,000 water per minute, 9,000 petroleum gas per minute, 3,420 iron ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is personal battery needed for science packs?
Not directly. It feeds Personal battery MK2, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
