EV512G-103 DATASHEET
Gel Cell Traction Industrial Battery Block
BENEFITS & FEATURES
Discover® Gel Cell Traction Series provide superior integrity and reliability. The maintenance-free, thick plate construction, designed to deliver excellent cycle life and very good run times at high operating voltages in tough industrial use with regular discharges, makes the EV Gel Series an excellent choice for robust industrial applications.
Advanced battery designs that exceed Original Equipment Manufacturer requirements. Enhanced alloy Traction heavy duty grids gives consistent active material adhesion and corrosion resistance for longer runtime and extended service life. Higher density active material paste to deliver longer runtimes at high discharge currents.

Due to self-discharge characteristics of lead acid battery technologies, all batteries must be charged within 6 months of storage to prevent a possible permanent loss of capacity as a result of sulfation.

CYCLE LIFE IN RELATION TO DEPTH OF DISCHARGE (25˚C)
Operation not recommended
IUI with Pulse Termination algorithm uses a pulse termination criterion. As a safety precaution during the Finish phase, if the average cell voltage, or volts per cell (VPC), exceeds U2 and the charger output has been on for more than 30 seconds, the output is shut off until the vpc falls to U3. The finish phase then resumes and this “pulsing” continues until the target overcharge (108% - 112%) is reached.
