Solarmax Maintenance Free Battery 80AH Battery + Digital Solar Charge Controller

Manufactured with thick seperators and advanced valve regulated technology, solarmax deep cycle batteries save you from acid leakage and frequent maintenance. Proprietary quinary alloy plates and specially treated plate grids enable low internal resistance and high discharge currents of up to 10 times the battery rated capacity. Made of high purity materials, solarmax  deep cycle batteries reduce the monthly Self discharge Rate below 3% at 77℉ (25℃), which is 5 times lower than their flooded counterparts. Improved electrolyte Formula ensures stable battery capacity and outstanding discharge performance at low temperatures below 32℉ (0℃). Length of Cycle services is significantly affected by depth for discharge (primarily), along with ambient temperature, discharge Rate, and the way the battery is recharged.
