How to use

To use the Evolveo LiPower 186 Core 2500 batteries, insert them into a compatible Li-ion charger that supports the 18650 format, ensuring the polarity matches the markings on the charger. Once fully charged, insert the batteries into your device, paying close attention to the positive and negative terminals. When the device indicates low power, remove the batteries and replace them with a fully charged set to continue operation. Always ensure the charger is set to the correct voltage and current settings as specified for lithium-ion chemistry.

What to consider before purchase

• Verify that your device specifically requires 18650-sized lithium-ion batteries.
• Ensure you have access to a compatible Li-ion battery charger.
• Check the voltage requirements of your device to ensure compatibility with 3.7V cells.
• Consider purchasing a secondary set if you require continuous, long-term operation for remote devices.

Usage recommendations

For optimal battery health and longevity, avoid deep discharging the cells below 2.5V and use a high-quality charger with a recommended current of 1–2 A. Store batteries in a cool, dry place when not in use for extended periods.
