The less the battery is discharged the greater the number of cycles possible.



For me the problem I find with flooded batteries, as they reach near the end of their useful life, they require a lot of water. My original Harris batteries only need about a cup of water every month during the summer for the first two years. During the third year, I was using about a pint of water every two weeks. I changed to a couple of Walmart's flooded batteries the 4th year and have only add a table spoon of water every other month.

One of the things I like about flooded batteries is that they seem to give plenty of warning that they are about done, AGM batterie seem to work fine until all of a sudden they don’t. I like to have shopping time.
