Re: Distilled Water for Battery?

If the old battery ever DID work, and was a lead-acid battery, then it had been filled originally. When new batteries are shipped "dry", they need to be filled with sulfuric acid before being charged the first time. After that, distilled water must be added when the levels get low. Some lead-acid batteries are "sealed" instead, but they are usually smaller ones (perhaps your lawnmower battery) without the capability for deep discharge/charge cycles.
