12V 250Ah Gel Battery Deep Cycle Solar Lead Acid Batteries

Gel battery are the most commonly used type of battery in photovoltaic systems, with a designed floating life up to 20 years. The solar gel battery is an improvement of the ordinary lead-acid battery with liquid electrolyte, replacing the sulfuric acid electrolyte with the colloidal electrolyte, which improves the safety, storage capacity, discharge performance and service life.

SAIL SOLAR Supply 250Ah Gel Battery For Off Grid and Hybrid Solar System Use 

Product Structure and Principle

Structure and Principle

      >Sail Solar deep cycle gel battery adopts super corrosion-resistant alloy and unique patented grid structure, so can improve the lead plates corrosion-resistant performance in high temperature.

     >It adopts special positive negative lead plates ratio and unique gel electrolyte, so can improve battery overpotential of hydrogen evolution effectively and high reduce the water loss in high temperature environment

     >Its paste formula is added anti-high temperature expanding agent, so can work continuously in high temperature environment

    >Sail Solar battery’s shell adopts anti-high temperature material, so the battery inside will not be over heat lead to water loss because of high temperature environment, ensure the battery super long life and the shell will not swell even use in extreme high temperature area

     >Its formula is added special super expanding agent which ensure battery discharge capacity is higher than other normal battery when work in low temperature, thus even the battery work in -40℃ area, it can work stable and continuously
