Cronex is virtually maintenance free. All of the acid is absorbed in the special plates and separators, so never need to worry about harmful acid leaks. Because of its lead calcium design, the AGM battery will hold its specific gravity more than three times longer than conventional lead antimony types. And to remain factory-fresh the AGM battery is shipped dry along with its own pack of high-gravity acid that’s added at the time of installation.
The unique combination of AGM with specially chosen Lead Alloy results into increased corrosion resistance, better performance in high temperatures, minimum self-discharge, longer shelf life and longer service life. These batteries are completely Sealed Maintenance Free.
