Yuasa (Enersys) Genesis NP10-6 6 Volt 10 Amp Hour Sealed Lead Acid Battery w/ 0.250 Fast-on Connector - UPS Battery Center, PPS-NP10-6F2-batt

• The construction and sealing techniques of the Genesis NP battery guarantee leak proof operation in any position with no adverse effect to capacity or service life. All Genesis NP batteries utilize an electrolyte suspension system consisting of a high porosity, glass fiber material which in conjunction with plates, totally absorb and contain the electrolyte. No silica gels or any other contaminants are used. Genesis NP batteries incorporate a built-in design that controls gas generation and induces recombination of more than 99% of gases generated during float usage. There is no need to check specific gravity of the electrolyte or add water to Genesis NP batteries during float service life. In fact, there is no provision for this type of maintenance. All Genesis NP batteries are equipped with safety release valves, designed to operate between 2 and 5 psi and automatically reseal. Hence, there is never an excessive accumulation of gas within the battery.
