Wilsons Sandbox

I got a new battery on Wednesday and filled it up with acid. Wednesday night, charged at 1 amp for four hours. Thursday night, charged at 1 amp for two hours. Friday night charged at 1 amp for two hours. (these hours were what was available while I was at home). Four of the cells only raise three of the balls in the hydrometer. I've never had this problem with a new battery before, or charging one while servicing. All cells should float either four or five of the balls. Should I continue charging this battery?
