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.
The advantage of making a battery up from individual cells is that if one cell fails, you replace that cell. You can add to your battery bank at any time with Nickel Iron batteries if you need to store more power. This cannot be done with lead acid batteries without reducing the life of the new batteries.
