You need 5 Alien Batteries to repair the Command Ship in 99 Nights in the Forest, though only 4 are required to collect, since one is attached by default. Use the Alien Battery Scanner beside the broken ship to reveal 5 nearby battery locations on your map temporarily. Batteries can be found at Alien Sites, Alien Outposts, Alien Ponds, Alien Drops, and Alien Scanners scattered across the map.

Repairing the Command Ship is the first real objective of the Alien's Revenge event, but finding 5 Alien Batteries scattered across a large map without knowing can eat up most of your night. Thankfully, there's a scanner sitting right next to the broken ship that points you in the right direction. So, to help you find all the batteries, this guide covers every battery location type, how the scanner works, and what to do once you've got all your batteries collected.
How Do You Find Alien Batteries in 99 Nights in the Forest?
There is an Alien Battery Scanner positioned beside the broken-down ship near the campfire. Interact with it to scan for nearby alien locations. It reveals 5 locations at once and marks them on your map. This marking is temporary, so you need to remember the general direction of each marker and start heading toward them before they disappear.
The scanner doesn't guarantee all 5 markers are the same location type. You will mostly get a mix of Outposts, Ponds, Drops, and Sites depending on what's nearby. If you can't find the locations, you can always rescan to reveal the spots again.
What Are All 5 Alien Battery Locations in 99 Nights in the Forest?
There are five distinct location types where Alien Batteries can be found, each with a different amount of effort and risk involved. Here's all the five locations:
| Location Type | How It Works | Combat Required |
|---|---|---|
| Alien Sites | A passive loot drop. An alien chest and battery sit underneath the structure with no mobs guarding it | None |
| Alien Outposts | A large guarded tower with multiple alien mobs. Clear the guards, then climb to the top to collect the battery and chest | Yes |
| Alien Ponds | Green-colored mutated ponds found across the map. Fishing here fetches you an Alien Battery directly | None |
| Alien Drops | Blue-colored launch pads. Defeat alien mobs and bring 3 corpses to the pad, which then spawns a chest and battery | Yes |
| Alien Scanners | A smaller purple pad similar to an outpost. Defeat nearby alien mobs and bring one corpse to the scanner to spawn the battery and chest | Yes |
Alien Sites are the easiest and fastest source as no fighting required, just walk up and loot. Alien Ponds are similarly safe if you already have a fishing rod, making them worth checking whenever you pass a green-tinted body of water.
Alien Outposts and Alien Drops require active combat, with Drops specifically needing 3 corpses delivered before the reward spawns. Alien Scanners need fewer kills than Drops but still require at least one corpse to trigger the chest.
How Do You Repair the Alien Command Ship in 99 Nights in the Forest?
Bring your collected Alien Batteries back to the Command Ship near the campfire and place them into the ship's open hood. You technically only need to find and deliver 4 batteries, since one slot is already filled by default. But the ship still counts toward the full set of 5 once that default battery is included.
Once all slots are filled, the ship repairs itself, lifts off the ground, and a green light beam shines underneath it. Walk into the green light to start levitating upward. This is how you board the Command Ship and begin the next stage of the Alien's Revenge event.
The scanner on the ship updates to show your remaining locations each time you return with a battery, so you don't need to remember everything in one trip. Drop off what you have, rescan, and head back out for the rest.
