Batteries in Subnautica 2 are the backbone if you want to progress the game, small to craft but required for scanners and electronics. You can harvest the required raw materials very easily to craft a battery. This guide shows you the required materials, where to obtain them and crafting a battery.
Raw Materials To Craft Battery

To craft a battery, you’re going to need 2 main resources – copper and acidic raion pouch. Luckily for us, these can be found in the surrounding area of the lifepod.
Obtaining Copper

Copper can be found just like titanium, you need to look out for brown ore as shown in the above image, with this you can also craft copper wire which will be useful to craft electronics.
Obtaining Acidic Raion Pouch

You can obtain the Acidic Raion Pouch by harvesting the purple plant, which kinda looks like multiple brains have been combined into one as shown in the above image.
After you’ve collected both the materials, use the fabricator to craft a Battery. You’re going to need 2 copper and 1 acidic raion pouch to craft 1 battery.
