Setup and Installation
- Initial Charge: Before first use, fully charge the battery. Connect the charging cable (not included, typically USB-C) to the battery unit and a suitable power adapter. The charging indicator light will show charging status.
- Battery Insertion: Locate the battery compartment on your Roilpet cat water fountain. Carefully insert the charged battery into the compartment, ensuring proper alignment with the connectors.
- Secure Placement: Close the battery compartment cover securely.
- Power On: Once the battery is installed, the fountain should power on automatically or can be activated via its power button.
Operating Modes
The Roilpet Cat Water Fountain, when powered by this battery, supports three distinct operating modes to suit your pet's needs and conserve battery life.

- Continuous Mode: Provides a constant 24/7 flow of fresh water. This mode ensures water is always available but consumes more battery power.
- Sensor Mode (Reaction): The fountain automatically dispenses water when your cat approaches within approximately 5 feet (1.5 meters) and detects movement. Water flows for 30 seconds with each detection. This mode significantly extends battery life.
- Timing Mode: Water is dispensed for a 30-second duration every 30 minutes. This mode offers a balance between water availability and battery conservation.
Refer to your Roilpet Cat Water Fountain's manual for specific instructions on how to switch between these modes using the fountain's control panel, which typically includes buttons labeled "Timing" and "Reaction" (Sensor).
Battery Life and Charging
The 4000mAh built-in rechargeable battery offers impressive battery life depending on the operating mode:
- Up to 90 days in Sensor Mode/Timing Mode (based on 1 cat household).
- Up to 48 hours in Continuous Operation Mode.
The battery is removable and can be charged independently, allowing for convenient charging without needing to move the entire fountain. This also prevents potential wire chewing by pets.

Maintenance
- Charging: Recharge the battery when the fountain's power indicator shows low battery or when performance diminishes. Use a compatible USB-C charging cable and power adapter.
- Cleaning: While the battery itself does not require cleaning, ensure the battery compartment within the fountain remains dry and free of debris to maintain good electrical contact.
- Storage: If storing the battery for an extended period, charge it to approximately 50% capacity and store in a cool, dry place. Avoid extreme temperatures.
