Conexpro brand gel batteries with output voltage 12 V , capacity 150 Ah , 10-12 year life is equipped with two M8 connectors for connection to the device. GEL technology involves the absence of liquid electrolyte in the battery. The electrolyte is firmly embedded in a hybrid gel , which is a combination with AGM technology. As a result, the electrolyte is fixed in the battery core, which prevents its leakage. A strong grid of cells ensures high durability of the battery during cyclic use . Key Features • Cyclic and continuous operation • Fantastic power-to-size ratio • Absolutely maintenance-free (in terms of water refilling) • Higher resistance to vibration , corrosion and wear • Fixed separator against short circuits • ABS plastic housing for longer life • Deep Discharge Resistance (Resists deep discharge better) • Safer and more ecological operation Suitable for the following applications • Backup sources and UPS • Electronic fire protection systems • Electronic security systems • Telecommunications equipment • Emergency lighting • Powering electric motors and other traction EV applications • Backup of circulation pumps and boilers
