What it is used for
One Basic Battery uses 1 Acidic Raion Pouch + 2 Copper. One Mild Acid uses 2 Acidic Raion Pouches + 1 Copper. Making both requires three pouches and three Copper; the Processor also needs a separate Copper Wire and two Titanium.
If you are making a Processor and a Basic Battery together, the complete raw budget is 3 pouches, 5 Copper and 2 Titanium. Two Copper become the separate Copper Wire used by the Processor.

How to handle it early
- Take the Survival Multitool to the cave below the Lifepod or the nearby east cave and look for Acidic Raion.
- Harvest the pouch, then collect two Copper if your next craft is a Basic Battery.
- Reserve one pouch per Basic Battery, or two pouches per Mild Acid at the Fabricator.
- For one Basic Battery and one Processor, reserve three pouches, five Copper and two Titanium, including the Copper Wire and Mild Acid components.
Pouches and Mild Acid are different items
Acid Rain Pouch and Acidic Rain Pouch refer to the Acidic Raion Pouch used by the recipes above. Mild Acid is a crafted output from the pouches, not another name for the raw pickup.
