Deep Cycle Battery
This isn't "electrical wiring" but you guys are pretty knowledgeable so I thought I might ask this here.
Four months back I replaced a battery back-up sump pump battery for a friend. I had told her to periodically check the water level but for whatever reason she didn't get around to it. Yesterday we added a little better than 3 quarts of distilled water to the battery (it's a size 27). That seems like a quite a bit of water. This is an ordinary deep-cycle type battery.
