2. Safety Information
Please read and understand all safety warnings before using these batteries. Failure to follow these instructions may result in fire, explosion, or personal injury.
- DO NOT recharge these batteries. They are single-use.
- DO NOT puncture, disassemble, or modify the batteries.
- DO NOT expose batteries to fire or high temperatures.
- DO NOT short-circuit the battery terminals.
- DO NOT expose batteries to water or other liquids.
- Keep batteries out of direct sunlight and away from heat sources.
- Store batteries in a cool, dry place.
- Keep batteries out of reach of children and pets.
- If a battery leaks, avoid contact with the fluid. If contact occurs, wash thoroughly with soap and water. Seek medical attention if irritation persists.
- Dispose of used batteries according to local regulations. Do not dispose of with household waste.
3. Setup (Installation)
These CR2 batteries are commonly used in devices such as digital cameras, dog training collars, photo flashes, memory backup systems, and pocket pagers.
- Identify the battery compartment on your device.
- Open the battery compartment cover.
- Observe the polarity markings (+ and -) inside the compartment.
- Insert the CR2 battery, ensuring the positive (+) and negative (-) terminals align correctly with the markings in the device. Incorrect installation can prevent the device from functioning or cause damage.
- Close the battery compartment cover securely.

4. Operating
Once installed correctly, the RC CR2 3V Lithium Ion Battery will power your compatible device. These batteries offer ultra-high energy density and are designed for consistent performance in high-current drain devices.
- Ensure your device is turned off before installing or removing batteries.
- Replace all batteries in a device at the same time to ensure optimal performance and prevent issues caused by mixed charge levels.
- Remove batteries from devices that will not be used for extended periods to prevent potential leakage and damage.
5. Maintenance
Proper maintenance ensures the longevity and safety of your batteries.
- Store unused batteries in their original packaging or a non-conductive container to prevent short-circuiting.
- Avoid storing batteries with metal objects like coins, keys, or jewelry.
- Keep batteries in a cool, dry environment, ideally between 10°C and 25°C (50°F and 77°F).
- Do not expose batteries to extreme temperatures, as this can reduce performance and lifespan.
6. Troubleshooting
If your device is not functioning after installing new batteries, consider the following:
- Device Not Powering On:
- Check that the batteries are inserted with the correct polarity (+ and -).
- Ensure the battery compartment cover is fully closed.
- Verify that the device itself is in working order.
- Try a different battery from the pack to rule out a faulty battery.
- Short Battery Life:
- Ensure the device is compatible with CR2 Lithium Ion batteries.
- High-drain devices will naturally consume battery power faster.
- Check for any device settings that might be excessively draining power.
As these are single-use batteries, troubleshooting is primarily focused on correct installation and device compatibility.
