PS5 CMOS Battery: Preservation & Replacement
Why the CMOS Battery Matters
The CR2032 Lithium battery on the motherboard powers the "Real-Time Clock" (RTC). If this battery fails, your PS5 will lose its date and time settings every time it is unplugged. In a "no-internet" scenario, this can prevent digital games from launching due to license verification logic. On the **PS5 Pro**, maintaining this clock is essential for the PSSR AI-scaling timestamps.
🛠️ Teardown Essentials
This is a high-risk repair. Using the wrong tools will strip the internal security screws:
- Precision: T8 Security Torx & Phillips #00 (See Verified Repair Kits).
- Safety: Anti-Static Wrist Strap to prevent motherboard short-circuits.
- Organization: Magnetic Project Mat (Crucial for tracking 40+ screws).
- Consumables: Fresh CR2032 Lithium Coin Cells (Multipack recommended).
Step-by-Step Replacement
- Full Disassembly: You must remove the plates, fan, and main plastic housing. This reveals the inner metal shield that protects the motherboard.
- Locate the Battery: On the PS5 motherboard, the CMOS battery is in a circular socket near the Southbridge chipset.
- Release the Cell: Use a non-conductive spudger to gently push the metal tab. The battery will pop upward.
- Insert New Hardware: Replace it with a fresh CR2032 3V Lithium cell. Ensure the (+) side faces up.
