Basic Information

• Model: D12-65
• Type: Valve-Regulated Sealed Lead-Acid Maintenance-Free Battery
• Rated Voltage: 12V
• Rated Capacity: 65Ah (20-hour rate)

Product Features

• Long Lifespan: Utilizes mature plate manufacturing technology and unique formulation, with excellent corrosion resistance of the grid. The normal float service life can exceed 15 years (at 25°C).
• Excellent Performance: High-strength tight assembly process increases battery tightness, preventing active material shedding. The battery has extremely low internal resistance and excellent high-current discharge characteristics, improving performance by over 20% compared to ordinary batteries.
• Low Self-Discharge Rate: Made with high-specification, high-purity lead alloy materials. At 25°C room temperature, after 28 days of storage, the self-discharge rate is less than 3%, exceeding industry standards. The battery can be stored for over six months at room temperature without needing recharging.
• High Consistency: Automated production processes and advanced online monitoring equipment ensure superior consistency in plates and batteries, making them suitable for series and parallel applications.
• Safe and Reliable: Features a unique combined labyrinth terminal sealing technology to ensure no leakage or acid creeping throughout the entire lifecycle. Equipped with a special safety valve to effectively isolate external sparks.
• Easy to Use: Special oxygen absorption cycle design prevents electrolyte water loss during charging. The water content of the electrolyte remains almost unchanged during use, eliminating the need for water replenishment. The battery can be installed upright, on its side, or stacked, offering flexible and convenient installation.

Performance Parameters

• Charging Voltage: At an ambient temperature of 25°C, the charging voltage is 14.1-14.7V, and the charging current should not exceed 25% of the rated capacity value in amperes.
• Operating Temperature Range: Charging temperature range: 0°C to +40°C; Discharging temperature range: -20°C to +55°C.

Application Areas

• UPS Uninterruptible Power Supply: Provides backup power for computers, servers, and other equipment, ensuring continuous operation during power outages and protecting data security.
• Communication Systems: Used in communication base stations and other communication equipment to maintain normal operation during power interruptions, ensuring uninterrupted communication networks.
• Medical Equipment: Such as medical monitoring devices and emergency equipment, providing reliable power support in emergencies to ensure normal medical operations.
• 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 equipment such as surveillance cameras and alarm devices, ensuring the security system operates normally at all times to maintain safety.

Usage Precautions

• Charging: New batteries do not require charging before first use; they can be charged after initial use. The first three charges should each last no less than 10 hours. Use high-quality automatic current-limiting constant-voltage charging equipment for charging.
• Installation Environment: Batteries should be installed in clean, cool, ventilated, and dry locations, avoiding direct sunlight, heating, or radiant heat sources. The distance between batteries should be more than 20mm. The installation site should be well-ventilated. If possible, installing in an air-conditioned room with a constant temperature of around 20°C will extend battery life.
• Usage and Maintenance: Avoid overcharging, over-discharging, and deep discharging. Regularly measure the float voltage and internal resistance of the battery to promptly identify and replace underperforming batteries. Recharge promptly after each discharge. Do not subject the battery to overcurrent or overvoltage charging, and avoid long-term storage without use or prolonged floating without discharging.
