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.
1 Tap water may be usable in some regions.  When new, a deep-cycle battery may have a capacity of 70 percent or less. Formatting as part of field use will gradually increase performance. Apply a gentle load for the first five cycles to allow a new battery to format.
