All 3 Power Cells in WayneTech R&D are required to restore power and complete the early WayneTech laboratory objective in LEGO Batman: Legacy of the Dark Knight. The cells are hidden around the R&D floor, with two requiring small environmental puzzles before you can collect them.
| Power Cell | Exact Location | Required Action | Nearby Landmark |
|---|---|---|---|
| Power Cell #1 | Left side of the inactive generator | Simply pick it up | Main generator platform |
| Power Cell #2 | Elevated ledge near movable cart | Destroy boxes and push cart underneath ledge | Storage crate area |
| Power Cell #3 | Side room beside generator | Build attachment and activate red button | Breakable box stack |
| Bonus Objective | WayneTech analysis station | Complete symbol-matching puzzle | Bear analysis machine |
How to Find All 3 Power Cells in Waynetech R&D
Step 1: Collect the first Power Cell
Head toward the inactive generator in the center of the WayneTech R&D lab. Look directly to the left side of the generator platform to find the first Power Cell sitting openly on the floor without requiring any puzzle interaction.
Approach the generator area
Move into the central laboratory section and locate the large inactive generator device. The first Power Cell is positioned beside nearby equipment and can be grabbed immediately after entering the area.
Insert the first cell
Carry the Power Cell back to the generator and place it into one of the empty slots. This partially restores the machine and opens the path for the remaining objectives.
Step 2: Solve the cart puzzle for the second Power Cell
Travel toward the storage section near the cart and destroy the nearby crates. Push the movable cart completely to the end of the track so you can jump onto the elevated platform containing the second Power Cell.
Destroy the nearby boxes
Use standard attacks to break all destructible crates beside the cart. Clearing the debris gives enough room to move the cart into position for the platforming section.
Push the cart into position
Grab the cart and move it to the very end of the rail path. If the cart stops early, reposition Batman and continue pushing until it fully locks underneath the ledge.
Jump up and grab the Power Cell
Climb onto the cart, jump to the upper platform, and collect the second Power Cell. Bring it back to the generator and insert it into the next open socket.
Step 3: Unlock the third Power Cell beside the generator
Move to the side area connected to the generator room and destroy the boxes stacked on the right side. Build the newly revealed attachment and press the red button to release the third Power Cell from above.
Break the right-side debris pile
Attack the stack of boxes beside the generator-side wall. Hidden LEGO pieces will spill out and allow you to construct an interactive mechanism.
Build the attachment device
Interact with the loose LEGO pieces and complete the automatic build. This creates a functional switch system connected to the suspended Power Cell mechanism.
Press the red activation button
Activate the bright red button beside the attachment.
The machine will drop the third Power Cell to the floor, allowing you to collect and install it into the generator.
Step 4: Restore power and analyse the bear
After installing all three Power Cells, connect the generator to the power source. Interact with the WayneTech analysis machine and complete the matching puzzle to finish the laboratory objective.
Plug the generator into the power source
Carry the power connector from the nearby energy source and attach it to the generator input terminal. The entire lab system will activate once connected properly.
Start the analysis sequence
Walk to the analysis station containing the bear experiment and interact with the console. A symbol-matching interface will appear on-screen immediately after activation.
Match the correct symbols
Carefully compare the displayed elements and select the identical match. Once the correct icon is highlighted, choose the red icon on the left side of the interface to confirm the analysis and complete the objective.
| Mechanic | What It Does | Important Detail |
|---|---|---|
| Cart Positioning | Creates jump access to upper ledge | Must be pushed fully to the end |
| Buildable Attachment | Unlocks Power Cell release system | Hidden inside destructible crates |
| Generator Power Link | Activates analysis machine | Won’t work until all cells are inserted |
| Analysis Puzzle | Advances mission objective | Incorrect matches reset the interaction |
Critical mistakes to avoid
- Do not try activating the analysis machine before inserting all three Power Cells. The interaction remains inactive until full generator power is restored.
- If the cart refuses to move further, destroy any remaining debris blocking the rail path first.
- The third Power Cell will not appear unless you fully complete the LEGO build attachment beside the generator.
- During the analysis puzzle, selecting the wrong symbol can reset the sequence and waste extra time.
- Some players miss the first Power Cell because it blends into the generator lighting. Check the left side carefully before exploring elsewhere.
Rewards and progression unlocked
While the game does not provide a separate character unlock or major collectible reward for this sequence, the WayneTech R&D section is mandatory for story progression and introduces several recurring mechanics used throughout later Gotham laboratory missions.
| Completion Task | Unlock Result | Mission Impact |
|---|---|---|
| Collect all 3 Power Cells | Fully powers WayneTech generator | Opens next objective chain |
| Complete bear analysis | Finishes laboratory investigation | Advances story progression |
| Solve environmental puzzles | Unlocks hidden interactions | Reveals additional WayneTech mechanics |
