Product overview:

 Oulite GFMH high-temperature valve regulated sealed lead-acid battery series adopts new additives and special high-temperature curing process, so that the battery has a long floating charge cycle life under high temperature environment. The battery shell is made of flame retardant and high temperature resistant synthetic plastic ABS, which does not deform at 105 ℃. The safety valve adopts a new rubber cap with an expansion degree of no more than 3% under high temperature, and the unique ultra-fine glass fiber partition can effectively prevent water loss. 

GFMH series battery can be used in the environment of - 25 ℃~+75 ℃, and can be used in the temperature range of 15 ℃~+40 ℃ for a long time. With high performance and efficiency, it is an ideal choice for communication, power and energy storage industries in extreme environments. Product characteristics: GFMH series batteries have a wide range of operating temperatures, outstanding high-temperature performance, and can be used in the range of - 25 ℃~+75 ℃. The batteries can be used in the range of 15~40 ℃ for a long time· Corrosion resistant grid, with special high-temperature resistant additives added in the negative plate, greatly increases the battery life. At 35 ℃, the designed floating charge life is up to 10 years· The radiation grid structure makes the battery more capable of accepting charge and discharging large current· ABS engineering plastic shell, high and low temperature resistance, corrosion resistance, strong seismic resistance, not easy to deform· The improved superfine glass fiber partition is adopted, with excellent resilience, low internal resistance, high porosity and gas recombination rate of 99%. CW-M-109 sealant is used, which has strong viscosity, aging resistance, corrosion resistance and high toughness· The safety valve is an improved rubber cap with high exhaust pressure accuracy, which can prevent the battery from bulging or water loss.
