PowerSafe® Planté Batteries

PowerSafe® Planté batteries are engineered for a range of standby power applications that demand high performance and long life. These 2V batteries include the PowerSafe Planté YAP, YCP, YHP and U-YHP cells, all of which feature the traditional Planté positive plate design refined by over a century of EnerSys battery manufacturing expertise.

Right-sized reliability for life

The PowerSafe Planté cell can deliver 100% of its rated capacity throughout its entire life, a claim no other lead acid battery can make. This unmatched reliability eliminates the need to 'oversize' the battery to allow for reduced performance at the end of its lifecycle. With excellent performance at both high and low rates of discharge, PowerSafe Planté batteries offer an ideal solution for telecommunications, power generation and distribution, Uninterruptible Power Supply (UPS), emergency lighting and security system applications.
