ARC Raiders Worth Your Salt: Battery Prototype and Charger Locations

Treat Worth Your Salt as a first-come objective and inspect the delivery crate before doing anything else. If a charged battery is already in the crate, the round may no longer award completion to you.

1. Enter Rocket Assembly. Do not go straight to the prototype.
2. Find the delivery crate near the large exit. It is the open white box, not the closed prototype container.
3. Check whether a battery is already inside. If it is, leave and start a fresh raid instead of spending time on the other objectives.

This same lobby-shared-object pattern also appears in Keeping the Memory and A Prime Specimen.

You need Spaceport access and enough survivability to cross Rocket Assembly while carrying the battery. Because nothing needs to be extracted, a free loadout can work.

• Finish all five objectives in one raid.
• Dying before delivery means starting the quest sequence again.
• Expect raider traffic around Rocket Assembly and a brief exposed moment while charging.

Rocket Assembly is a large named structure in the northern to northeastern part of Spaceport, bordering Fuel Control and the East Container Yard.

1. Approach from the north when practical. This keeps the route simple and can reduce unnecessary ARC contact.
2. Enter the main hangar. Use the large industrial interior as your orientation point.
3. Check the delivery crate first. Confirm the raid is still worth continuing before climbing to the prototype.

You can pair the trip with Greasing Her Palms outside the building and Deciphering the Data at nearby Fuel Control.

The Battery Prototype is upstairs in a small closed box beside a row of red lockers. The red metal staircase and lockers are the most reliable visual cues.

1. Find the red metal staircase. Climb to the elevated walkway.
2. Follow the walkway toward the red lockers. Ignore conflicting compass directions and use the lockers as your confirmation cue.
3. Open the small closed box in the corner. Take the Battery Prototype.
4. Return to the hangar floor. Carrying the battery leaves you exposed, so clear nearby threats first.

The Industrial Charger is not marked on the map. Look on the hangar floor below the elevated metal walkway, around the central machinery near the large exit.

1. Return down from the prototype walkway. Head toward the machinery below where the bridge or walkway ends.
2. Find the white charger box and highlighted battery slot. Use the machine's panel as the confirmation cue.
3. Insert the Battery Prototype. Place it into the highlighted slot.
4. Activate the charge control. Use the machine's side control to begin charging, then wait a few seconds.
5. Take the Charged Battery. Move immediately toward the delivery crate.

Deliver the Charged Battery to the open white box in a corner beside the large exit, near the metal supports and corrugated wall.

1. Use the large exit as your anchor. Search the nearby corner rather than the upper walkway.
2. Identify the open box. This distinguishes it from the closed box that held the prototype.
3. Place the Charged Battery inside. Delivery completes the quest immediately.

No extraction is required after the battery is delivered. If you skipped the earlier check, confirm the crate is not already occupied before doing the full route.

After delivery, check Celeste's available quests and continue from the objectives that open in your current progression.
