OE style INTERPOWER cover dsign is truly maintenance free.
Carrying handles on INTERPOWER makes the batteries easy to carry and to install.
INTERPOWER calcium alloy positive and negative grids reduce water loss and self discharge, increasign cranking performance.
Thin-walled, high impact polypropylene case reduces breakage while creating more room for power producing plates and acid which increase the total electrolyte capacity.
Terminal design that provides maximum resistance to acid leaks, seepage, corrosion and black post, keeping the terminal posts clean and corrosion free on the shelf.
Large reservoirs above the plates provide ample electrolyte reserve for longer maintenacne-free performance and life.
Thicker calcium ally positive grids are enhancing the durability against high heat and high energy consumption and resisting vibration damage for trouble-free service.
Envelop separators that are designed to virtually dliminate shorting and "corrode-through", dramatically imporving reliability and service life.
