Long Lifespan – Fullriver FSG Sun Gel batteries typically last longer than their lead acid counterparts due to 99.994% pure virgin lead, thick plates, no maintenance needed, and a proprietary design and gel electrolyte! The FSG series offers a float service life of 20 years and approx. 2750 cycles @ 50% DOD!

Advanced Gel Electrolyte – Fullriver’s proprietary thixotropic gel formula prevents stratification and increases cycle life! Gel batteries also offer exceptional performance for slow-discharge applications and extreme temperature environments!

Outstanding Warranty – Fullriver FSG batteries come with a 10-year solar warranty, offering you peace of mind and confidence in your choice of Fullriver Battery!

Flexible Installation – Gel batteries can be installed in almost any orientation (except upside-down and must be greater than 5-degree angle when placed horizontally), which allows you to fit them in places traditional wet cell batteries can’t! Gel batteries are recombinant and do not off-gas like traditional wet cell batteries which means you can mount them within the cabin as well as no more cleaning corrosion from the terminals!

OEM Racking and OPzV Sized – Fullriver FSG is offered with Fullriver-engineered racking and interconnects for an all-in-one solution! They are also OPzV sized to easily fit in existing OPzV installations and equipment!
