CSB HC1217W Special Application UPS Battery

Purchased this and received it within 5 days. Fits right into my UPS unit and the plugs fit perfectly. I would recommend this over the other brands that make this such as Power-Sonic, had very bad luck with a batch of those. The only thing I wish SEP would offer is a disposal program where I can send my old unit into a certified recycle center. I don't like the idea of throwing these into the landfill. I’ve noticed that this type of battery can “over-charge” and the casing expands to the point where you have to pry the spent unit out of the UPS unit, is there a way to prevent this?
