It’s doable with basic tools and patience. Here’s a general approach you can use at home:

1. Confirm your controller version: Check the label on the back for CUH codes (e.g., CUH-ZCT1 or CUH-ZCT2).
2. Choose a compatible 3.7V battery: Match the connector and form factor to your model.
3. Power down: Turn off the console and controller.
4. Open the shell: Remove screws, gently separate the halves, and avoid pulling ribbon cables.
5. Disconnect and swap: Unplug the old battery by its connector (not the wires) and install the new one.
6. Reassemble and charge: Close it up and charge fully before use.

If you’re unsure, seeking help from a repair pro can reduce the chance of damage.

DualShock 4 controllers use a 3.7V rechargeable lithium battery, but the form factor and connector vary by revision.

• CUH-ZCT1 (earlier version): Typically uses one battery style and connector.
• CUH-ZCT2 (newer version): Uses a slightly different form factor/connector.

Check the model code printed on the back of your controller and match it to the product listing’s compatibility notes. Capacity options range from about 1100mAh to 2000mAh; higher mAh can offer longer playtime, though results depend on features like vibration and light bar brightness. On Walmart.com, you can filter by model compatibility and capacity to narrow your choices.

Prices can vary for several reasons, so it helps to compare options:

• Capacity (mAh): Higher capacities often cost more due to longer potential playtime.
• Included extras: Some kits add tools or a USB cable.
• Compatibility details: Batteries tailored to specific controller revisions may differ.
• Warranty and build: Protective circuitry and materials can influence cost.
• Availability: Stock levels and shipping method can affect total at checkout.

To find current pricing without overpaying, use filters for capacity and compatibility on Walmart.com and review customer feedback. Selecting pickup or delivery can also help you plan timing and convenience.

Try a few quick checks before considering a battery replacement:

1. Charge fully: Use a known-good USB cable and port; let it charge for at least 60 minutes.
2. Reset the controller: Press the small reset button on the back for 5–10 seconds, then reconnect via USB and press the PS button.
3. Try different ports/cables: Some ports don’t deliver consistent power.
4. Check for damage: If the battery won’t hold charge, a replacement may help.

Playtime depends on usage and settings, and results can vary. If you notice swelling or physical damage, stop using the controller and address the issue before further troubleshooting.

Think about how you play and your controller revision:

• Capacity vs. playtime: Higher mAh (e.g., ~1800–2000mAh) can extend sessions, but actual runtime varies with vibration and light bar brightness.
• Charge time: Bigger batteries may take longer to charge.
• Fit and connector: Match form factor to CUH-ZCT1 or CUH-ZCT2 to ensure a proper install.
• Usage habits: If you often play wired or disable vibration, standard capacity may be enough.

On Walmart.com, filter by compatibility and capacity, and check customer reviews to see how different batteries perform in real-world use.
