Features and Benefits

• Ten year design life in standby float service.

• A recognized component of U.L.

• Non-spillable valve regulated lead acid battery (VRLA) design.

• Advanced absorbed glass mat technology (AGM) with gas recombination greater than 99%.

• Operates at a low internal pressure.

• Never needs watering, minimal maintenance.

• Advanced lead tin calcium alloy, reduces grid corrosion

and promotes long battery life.

• Shock absorbent thick wall polypropylene cases.

• Cold forged non-porous terminal bushings eliminate post leakage.

• Thermally welded cover to case bond, eliminates both acid and electrical leaks.

• Over-sized, through the partition inter-cell welds provide low resistance connections with minimal power loss.

• Each cell has a low pressure safety release venting system recognized per U.L. 924.

• Measured high vacuum acid fill reduces electrical variability between cells.

• 100% recyclable materials.

Applications

• UPS • Emergency lighting

• Switchgear • Alarm and security

• Telecom • Overhead cranes

Operating specifications
• Operating temperature range: -40ºC/-40ºF to 60ºC/140ºF

• Charging voltage / current: 2.27 to 2.30 volts per cell, constant voltage at a maximum

current of C/4 amps.

• Temperature compensation: Apply for temperature range of 0ºC/32ºF to 40ºC/104ºF.

Subtract 3 mV/ºC/cell or 1.7 mV/ºF/cell, above 25ºC/77ºF.

Add 3mV/ºC/cell or 1.7 mV/ºF/cell, below 25ºC/77ºF.

• Storage time from a fully 6 months at 25ºC/77ºF. For each 9ºC/15ºF rise,

charged condition: reduce the storage time by half.
