High energy density, sealed leak proof construction, excellent performance and long service life make the NP series the most reliable battery available. | | | Features: | |
• The construction and sealing techniques of the Genesis NP battery guarantee leakproof 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.

Works in my alarm system very wellFeb 13, 2010
This battery replaced a similar one (exact specs) in my home alarm system. Hooked it up in under one minute. The terminals fit perfectly. Battery appears pretty well-built. System charged battery up and was fully operational within a few hours (normal). Would not hesitate to buy this one again!

After reading the reviews, I chose not to take a chance on the Radio Shack option. The price was right, my purchase was delivered in a timely manner, and all is now well with the world.
Great ProductMay 07, 2009
