Dell Latitude E5550 Battery Replacement

In the office we tend to buy Dell Desktops and Laptops. In my opinion they are no better or worse than any other brand and are priced competitively. Normally we have a 3-4 year cycle moving old equipment out and new equipment in. This one E5550 has been hanging around for whatever reason and was feeling slow. I originally popped the back cover to upgrade to a SSD and noticed the battery was in bad shape and needed to be replaced.

From the looks of it, two of the cells out gassed and have a belly. This is very bad since the battery capacity is obviously reduced. It is also dangerous to the hardware since the added pressure from the battery could damage the system board or cause the case to crack.
