The grid | Xtreme VR series represents the highest level of development of today's pure lead batteries in AGM technology and is trend-setting in terms of energy and power density for lead-acid storage technologies.

They were developed to meet customer requirements for increased performance and durability, as well as for use at elevated ambient temperatures.
Due to its design as a top and front terminal version it is optimally suited both as a UPS battery in data centres and as a back-up battery in telecom applications.
The basis of the pure lead technology is the maximisation of the number of electrodes installed and the resulting larger electrochemical reaction surface, which results in a greater energy and power density for lead-acid storage technologies.

In the development of the HOPPECKE grid | Xtreme VR batteries, the focus was deliberately placed on the reworking and optimisation of all components in order to be able to fully exploit the performance gain of pure lead technology. This has redefined the standard for maintenance-free sealed batteries (VRLA).
