Nothing to report product that seems reliable

A first copy of this battery was commissioned in July 2013 and that the UPS team work correctly in case of power failure or when disconnected from the power grid (as a test). Three new batteries were therefore be ordered and installed on our desktop inverters whose original batteries were HS. A priori product so carefree, but expect 1 or 2 years to conclude (the original battery had held 3-4 years).
