M18 Batteries still falling apart..

Hi,

I manage a mechanic shop and was wondering what everyone's opinion on the new forge batteries are? Are they actually tougher than the regular M18? Anyone who uses heavy duty M18 tools with a lot of torque/vibration know that they split after a while. Our last 5.0's only lasted 5 months before they had to be glued and stapled. Tired of trying to warranty batteries that are otherwise fine but the housing has separated. So, in your opinions, are forge batteries actually tougher?
