With a minimum capacity of 3000mAh LiFePO4 Battery and nominal 3200mAh, this battery provides extended runtime for your devices. The 0.2C standard discharge (to 2.0V) ensures that power is delivered steadily, avoiding sudden shutdowns – ideal for back-up power systems where consistent energy is non-negotiable. Whether powering small electronics or emergency devices, the high-capacity backup battery keeps your equipment running when you need it most.
Designed to adapt to extreme conditions, the battery offers a discharge temperature range of -20~60℃ and a charging range of 0~60℃ (60±25% R.H.). This wide temperature range battery performs reliably in cold outdoor settings (such as winter camping gear) and hot industrial environments, eliminating concerns about temperature-related performance loss. Note: Charging below 0℃ may reduce capacity and cycle life, so we recommend charging within the optimal 0~60℃ range.
Safety is paramount in our design. The low internal resistance battery (≤25mΩ) minimizes heat generation during charging and discharging, reducing the risk of overheating. The LiFePO4 chemistry is inherently stable, with no memory effect, ensuring the battery retains its capacity over repeated charge-discharge cycles. Additionally, compliance with UN3480 standards guarantees that the battery meets strict safety criteria for transportation and usage.
Save time with flexible charging options: the fast-charging LiFePO4 battery supports 0.2C standard charging (600mA, ~6 hours full charge) for daily use and 1C rapid charging (3200mA, ~1.5 hours full charge) for emergencies. The maximum continuous charging current of 1C (3200mA) and maximum continuous discharge current of 3C (10.5A) ensure efficient power delivery, making it suitable for high-demand devices that require quick energy replenishment.
The battery features a long storage temperature range of -20~25℃ (60±25% R.H.), with a recommended storage period of no more than 6 months (3 months for battery packs with protection circuits). A simple recharge every 3-6 months maintains its performance, making the long-cycle replacement battery a practical choice for users who need a backup power source ready for use at any time.
Ideal for home or office back-up power replacement, this battery serves as a reliable energy source for emergency lights, portable generators, and uninterruptible power supplies (UPS). Its 3000mAh capacity ensures that critical devices remain operational during power outages, providing peace of mind in unexpected situations.

The charging time depends on the charging current:
• Standard charging (0.2C, 600mA): Approximately 6 hours (reference time).
• Rapid charging (1C, 3200mA): Approximately 1.5 hours (reference time).
We recommend using a charger that matches the battery’s charging voltage (3.65V±0.03V) for optimal results.
Store the battery in a cool, dry environment with a temperature range of -20~25℃ (60±25% R.H.). For maximum lifespan:
• Do not store for more than 6 months without charging.
• For battery packs with protection circuits, recharge every 3 months.
• Avoid storing the battery in fully charged or fully discharged states; a 50% charge level is ideal.
Yes! The battery can discharge at temperatures as low as -20℃, making it suitable for low-temperature applications. However, charging below 0℃ is not recommended, as it may reduce capacity and shorten the cycle life. For cold-weather use, charge the battery at room temperature before deployment.
The maximum continuous discharge current is 3C (10.5A), which is suitable for high-power devices that require instant energy delivery. Please ensure that your device’s current requirements do not exceed this limit to avoid damaging the battery or the device.
