PowerSafe® DU Batteries

The DU battery series has been designed with the edge of the plates oriented perpendicular to the rack rails for full plate edge visibility. The dual hole (top/bottom) terminal design allows for easy maintenance.

The DU battery series employs the EnerSys® proven Slide-LockTM post seal that allows for natural plate growth over time without degrading the seal.

The innovative tongue-and-groove jar-to-cover seal provides reliability with a robust airtight seal.
