JJN 12V 100AH Gel Battery 2 Pack 100AH Deep Cycle Hybrid Gel Battery VRLA Rechargeable Gel Automotive Batteries for Solar Wind RV Marine Camping UPS Wheelchair Trolling Motor, Maintenance Free

?Maintenance Free & No Leakage? AGM and GEL batteries are both VRLA (Valve Regulated Lead-Acid) batteries. GEL batteries are a safer option than traditional lead-acid. Gel batteries adapt better to extreme temperatures and are less likely to experience thermal runaway. The GEL battery uses a silica type gel to suspend the electrolyte. JJN Deep Cycle Hybrid GEL Batteries save you from acid leakage and frequent maintenance. ?Extended Service Lifetime? Corrosion-resistant grids enable a design life of up to 8 years in standby applications and more than 1200 charge/discharge cycles at 30% DOD in cyclic applications. ?Longer Shelf Life? Made of high purity materials, JJN 100ah Deep Cycle Battery reduce the monthly self-discharge rate below 2% at 77? (25?), which is 5 times lower than their flooded counterparts. No need to recharge the dormant battery frequently. ?Excellent Deep Discharge Recovery? Proprietary plate composition and patented gel electrolyte ensures excellent recovery capability after excessive deep discharge. This means that GEL batteries can discharge more and still be recharged like new. Unlike Flooded batteries, they are not allowed to discharge too much. ?Wide range of uses? Can be used for RV travel, outdoor energy storage, solar wind power system, auto control system, electric vehicles, golf carts, trolling, UPS, yachts, etc
