Fortunately, the Arc Raiders community has mapped out the most reliable spawn areas. While exact positions vary slightly, batteries tend to appear in ARC Raiders Coins predictable zones around the fort's perimeter and on certain elevated positions.

Below are the most common locations you should check:

1. Small Perimeter Structures

Around the fort are several minor buildings, tents, and supply sheds-these are the most consistent battery spawn spots. Walk around the entire outside perimeter and peek inside:

Wooden shacks

Small storage huts

Lean-to shelters

Crates and supply boxes near the walls

Batteries often blend in with clutter, so move slowly and scan thoroughly.

2. Ground-Level Corners and Exterior Walls

Many players overlook the simple spots: corners, shadows, and debris piles along the exterior walls. Batteries may spawn:

Against the lower edges of the fort walls

Near piles of rubble

Behind fencing and barricades

Do a full clockwise or counter-clockwise sweep around the fort to avoid missing any easy pickups.

3. Inside the Fort Interior

Although less common, some batteries appear inside the main interior hallways or rooms of the fort. Check:

Under staircases

Along the inner walls

Near scattered furniture or broken crates

Interior spawns often occur near the upper floors, so sweep upward levels if you come up empty outside.

4. The Top of the Ancient Fort

This is one of the most frequently overlooked-but highly reliable-battery spawn points.

Head to the very top of the fort's roof, where you'll find a wide platform with strong sightlines. Batteries occasionally spawn:

Near the central rooftop wall

Besides the roof-edge debris

Against railings or parapets

If you've located only two batteries and can't find the third, this elevated rooftop is the best place to double-check.

Completing the Puzzle

After collecting a battery, return to one of the three electrical boxes and insert it. There's no required order-you can power them in any sequence.

Once all three boxes are active:

All three lights above the cellar glow green.

A mechanical unlocking sound plays.

The cellar door swings open.

Climb down the ladder inside to reach a compact loot room. The rewards vary from modest to excellent depending on RNG, but this location is always worth a stop if you're already in the area.

Be aware: the noise of the door opening and the loot room can attract nearby players or hostile units, so keep your guard up. Other raiders might try to buy ARCR Coins snag the ARCR Items you worked for.
