Batteries

Suitcases, camps, and underground facilities across the island.

Before you go

Search luggage near the crash site as part of your initial supply sweep.
Inspect abandoned camps and other visible container clusters while traveling between objectives.
At cannibal camps, deal with nearby threats before opening containers and gathering supplies.
During cave and bunker trips, check shelves and room containers along the route.
Keep batteries in your inventory rather than discarding them when a powered tool is part of your expedition plan.
Use batteries for gear that requires them and note when your reserve is getting low.
On the next surface or facility run, search additional containers and replenish the reserve.

Container contents vary, so gather batteries alongside tape, rope, and other useful loot.
Avoid spending the last of your reserve on gear you do not need for the next trip.

Repeatable through ongoing scavenging, but individual containers are not guaranteed battery sources and should not be treated as renewable deposits.

Expecting a specific suitcase to contain batteries every time; check multiple sites over multiple trips.
Ignoring batteries while inventory space is available; they support useful powered equipment.
Using the full stock without a plan; preserve a reserve for the next exploration run.

Stop a detour when you have enough batteries for planned equipment use, then continue your main objective and gather more on later supply routes.

Materials and supplies

Batteries power equipment that consumes them and are useful to keep available for exploration and nighttime use.
