The EnerSys DataSafe CX-M battery is an economical multi-cell flat plate battery.  The CX-M unit is optimized for high performance and provides excellent short duration discharge rates. Alpine power systems is a platinum distributor of EnerSys battery products. Alpine’s Certified Technicians are able to provide turnkey design, installation, preventative maintenance, and recycling battery services nationwide.

The DataSafe C battery now features the Slide-Lock™ post seal design.  The DataSafe CX-M battery features a larger copper insert in the Slide-Lock post.  The number of plates and plate thickness are optimized with respect to the available electrolyte ensuring maximum performance during short duration discharges.

The DataSafe CX-M battery was designed for easier maintenance since all the posts and connectors reside above the cell cover; maintenance routines, including individual cell monitoring and intercell resistance measurements are simplified.  The economical design and footprint, combined with Slide-Lock post and excellent performance in short duration discharges makes this an ideal battery in UPS and switchgear applications.
