Basic Parameters 2 Model: C12-100. Rated Voltage: 12V. Rated Capacity: 100Ah. Dimensions: Length × Width × Height: 328×172×220mm. Weight: Approximately 30.5kg. Charging Temperature: 0-45°C. Discharging Temperature: -20-60°C. Maximum Discharge Current: 1500A (5 seconds). Cycle Life: ≥750 cycles (70% DOD). Performance Characteristics Excellent Safety Performance: Starved electrolyte design with no free-flowing electrolyte inside, no leakage during normal use, and can function normally even when tilted 90 degrees; valve-regulated sealed structure with an automatic safety valve that opens to release pressure when internal pressure is high, minimal accumulation of combustible gases, and excellent explosion-proof performance 3. Superior Maintenance-Free Performance: Utilizes the cathode absorption sealed maintenance-free principle, with a gas recombination efficiency exceeding 95%, minimal water loss during normal use, and no need for regular fluid replenishment maintenance 3. Environmentally Friendly: No acid mist during normal charging, does not pollute the equipment room environment or corrode equipment room devices 3. Low Self-Discharge: Uses Pb-Ca-Sn alloy with high gas evolution potential; can be stored in a dry environment at 20°C for six months and put into normal use without recharging 3. Wide Operating Temperature Range: Can operate stably between -10°C and 45°C 3. Good High-Current Performance: Tight assembly process with low internal resistance; can discharge at 3 times the rated capacity for 3 minutes or 6 times the rated capacity for 5 seconds without abnormalities 3. Long Service Life: Uses high-purity raw materials and a long-life formula, along with battery consistency control processes; normal float charging design life can reach 7-10 years (≥38Ah) 3. Excellent Battery Consistency: Controlled from the source through grid design, paste quantity, etc.; plates are weighed and graded before assembly, acid is quantitatively injected, and a four-charge three-discharge formation system is used; discharge matching is performed before assembly, and static testing and secondary matching are conducted before shipment to ensure discharge and float charging consistency 3. Structural Design Grid Structure: Mid-tab and bottom-corner staggered design; 2V series positive plates have a plastic protective film at the bottom; alloy uses lead-calcium-tin-aluminum alloy, with high hydrogen evolution potential for negative plates; positive plate alloy is high-tin low-calcium alloy, with fine and dense grain structure and good corrosion resistance 14. Separator: Uses imported corrugated PVC separator specifically for gel batteries, with high porosity and low resistance 14. Battery Case and Cover: Made of ABS material, sealed with epoxy resin to ensure no leakage 14. Terminals: Made of pure lead with good corrosion resistance; terminals and battery cover use a compression ring structure, sealed with resin adhesive to ensure sealing reliability 14. Gas Filter and Explosion-Proof Device: Equipped in all 2V and 12V series batteries; no external flames, and evolved gases are filtered to prevent environmental pollution 14. Application Areas Uninterruptible Power Supply (UPS): Effectively ensures system normal operation in environments with unstable power supply, providing backup power support for computers, servers, and other equipment 2. Solar Energy Storage Systems: Can be integrated with solar power generation systems to store excess electricity for use at night or on cloudy days, improving solar power utilization 2. Communication Facilities: Used for emergency power supply in base stations and other communication equipment, ensuring communication networks remain operational during power outages 2. Emergency Power Supply: Provides rapid and effective power support for emergency lighting, firefighting equipment, etc., during emergencies such as fires or earthquakes 2. Power Tools and Equipment: Provides strong power support in scenarios requiring mobile power, such as electric bicycles and forklifts 2. Medical Equipment and Instruments: Supplies stable power for medical devices like ventilators and monitors, ensuring normal medical operations 1. DC Power for Power Plants and Hydropower Stations: Provides DC power for control equipment and protection devices in power plants and hydropower stations, ensuring safe and stable operation of the power system
