Full Guide Intro
Battery power is one of the most valuable resources in Death Stranding 2. Nearly every advanced tool relies on energy, including Skeletons, support equipment, and several late-game traversal upgrades.
If you constantly find yourself searching for generators or running out of power during deliveries, upgrading your backpack battery should be a top priority.
How To Unlock Extra Batteries
The Extra Battery attachment becomes available after connecting Heartman's Lab to the Chiral Network during the main story.
Once unlocked, you'll gain access to:
Extra Battery Lv1
This battery attachment can immediately be equipped to increase Sam's total battery capacity.
How To Unlock Battery Upgrades
Additional battery upgrades are earned by increasing your connection level with Heartman's Lab.
Upgrade progression is simple:
| Upgrade | Connection Level |
|-----------|-----------|
| Extra Battery Lv1 | Initial Connection |
| Extra Battery Lv2 | 2 Stars |
| Extra Battery Lv3 | 3 Stars |
| Extra Battery Lv4 | 4 Stars |
Each new version provides more battery capacity than the previous model.
How To Increase Connection Level Fast
The quickest way to unlock battery upgrades is by completing deliveries for Heartman's Lab.
You can increase connection levels by:
- Completing Standard Orders.
- Delivering Lost Cargo.
- Finishing Sub Orders.
- Maintaining high cargo condition.
The better your delivery performance, the faster you'll unlock new battery upgrades.
How To Equip Extra Batteries
After unlocking a battery blueprint:
- Visit any connected facility.
- Open the fabrication menu.
- Fabricate the desired battery upgrade.
- Enter Backpack Customization.
- Attach the battery to an available backpack slot.
Once equipped, Sam immediately gains additional battery capacity.
What Uses Battery Power?
Battery upgrades affect almost every major piece of advanced equipment.
Extra battery capacity benefits:
- Battle Skeleton
- Boost Skeleton
- Bokka Skeleton
- Support equipment
- Certain backpack components
- Vehicle systems
Players who rely heavily on Skeletons will notice the biggest improvement.
Are Extra Batteries Worth It?
Absolutely.
Battery upgrades are among the strongest utility upgrades in the game because they improve dozens of systems simultaneously.
More battery power means:
- Longer sprinting.
- More Skeleton usage.
- Fewer generator stops.
- Better exploration.
- Increased combat efficiency.
Few upgrades offer as much value across the entire game.
The Drawback Of Extra Batteries
The biggest downside is backpack space.
Extra Batteries occupy a large portion of Sam's backpack, leaving less room for:
- Utility Pouches.
- Grenade Pouches.
- Stabilizers.
- Decorative items.
Players must balance battery capacity against other useful backpack upgrades.
Mini Batteries And Additional Power
Even after installing a large Extra Battery, smaller backpack accessories can provide additional power.
Combining:
- Extra Battery
- Mini Batteries
creates one of the largest energy reserves available in the game.
This setup is particularly useful for players who spend most of their time using Skeletons.

Death Stranding 2 Material Farming Guide: Best Ways to Get Metals, Ceramics, Resins, Chemicals, and Special Alloys
The fastest way to farm materials in Death Stranding 2 is by restoring and upgrading Mines across Australia. Mines generate large amounts of resources in exchange for Chiral Crystals and can be upgraded for even greater yields.
For early and mid-game farming, clearing Brigand Camps, claiming materials from facility terminals, and collecting abandoned resource containers from other players are the most reliable methods. Special Alloys are generally easiest to obtain through mines, while Metals and Ceramics are commonly found at enemy camps and distribution centers.
