• Emergency Lighting: Used in emergency lighting systems in buildings, public places, etc., providing illumination during power outages or emergencies to ensure safe evacuation.
• Security Systems: Powers security devices such as surveillance cameras and alarm systems, ensuring the security system operates normally at all times to maintain safety.
• Other Fields: Also applicable in telecommunications, power grids, financial industries, rail transportation, petrochemicals, smart manufacturing, automated control systems, small and medium-sized enterprise server rooms, and other areas.

Usage Precautions

• If the battery is stored for more than three months, recharge it; if stored for six months, perform a charge-discharge cycle.
• During use, avoid fully discharging the battery before recharging, as this significantly impacts battery life. Charge as needed until full, but avoid overcharging or over-discharging.
• When handling the battery, avoid dropping, rolling, or applying heavy pressure.
• Do not short-circuit the positive and negative terminals of the battery.
• Recharge the battery immediately after discharge to restore capacity. Do not leave the battery discharged for too long (over 48 hours) to prevent undercharging, which may make it unable to recharge next time.
• After discharge, avoid charging with high current (greater than 0.3C??A) for extended periods to prevent battery swelling.
