AGM Separator For Starter Battery


Starter batteries are a type of battery specifically designed for starting, lighting, ignition (SLI), and power supply of vehicles, ships, and airplanes. Generally referred to as car batteries or car starter batteries. When starting the engine, the battery must be able to supply continuous high current to the starter in a short period of time (5-10 seconds). For gasoline engines, the required starting current can reach 200-600A; for diesel engines, the required starting current can reach 1000A. Based on this working characteristic, starter batteries require large capacity and low internal resistance to ensure sufficient starting ability of the battery.

The AGM separator of the starter battery has strong ability to retain electrolyte and can evenly distribute the electrolyte, thereby ensuring the battery's capacity, performance, and lifespan. The AGM separator quickly absorbs electrolyte, thereby shortening the battery's charging and discharging time. Our company's starter battery AGM separator strictly controls the metal and halogen content in the product, with a low resistance of 0.0005 Ω, ensuring the battery's internal resistance demand. Our company's starter battery AGM separators are widely praised by customers due to their long-term supply to domestic well-known starter battery manufacturers such as Fengfan and Camel.
