Nov 29, 2011, 10:22 PM. We visited the Hoover Dam for the first time on our third trip. It was worth it. Get there early before crowds build and you needn't park in the parking structure--drive over the dam and park for free. Take some pics from the bridge on your way out.
It is best to check your new batteries regularly as this will give you a good feel for how often your application will require battery watering. WARNING: A brand new battery may have a low electrolyte level. Charge the battery first and then add water if needed.
After charging fully, disconnect the charger, do the rocking/tapping again, and let the battery sit for a few hours, not just minutes. Top up the battery with acid, to the upper level line. You will never be adding acid, only distilled water, to this battery again.
