Targeted Replacement for HP Pavilion dv7-2225ef

This DBTLAP CMOS battery is a direct replacement for the HP Pavilion dv7-2225ef laptop motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The product is a lithium coin cell intended solely for motherboard firmware power, not for main laptop operation. Buyers needing a primary power pack should look elsewhere.

New Lithium Cell with Pre-Shipment Testing

Each unit is supplied new and tested before dispatch to confirm reliable voltage output. The lithium chemistry provides stable long-term power for CMOS memory retention. Packaging includes a single battery without additional cables or mounting hardware. Installers should verify polarity orientation matches the motherboard socket before fitting.

Compatibility Check Before Ordering

Confirm the laptop model number matches dv7-2225ef exactly, as CMOS pinouts and form factors vary across similar chassis codes. This part suits motherboard RTC circuits only and will not power the main system. Ensure the existing battery is a removable coin type rather than a soldered component before purchasing.
