Performance & System Planning
Temperature matters. The supplied curves show shorter float life at elevated temperatures and lower available capacity in cold conditions.
Depth of discharge matters. Shallower cycling supports longer cycle life; no single cycle-life figure applies to every duty profile.
Storage matters. Self-discharge increases with temperature. Follow the manufacturer’s recharge schedule during storage.
Specify Your Battery Bank
Share your DC bus voltage, continuous load, peak load, required backup time, site temperature and charging source.
A 48V nominal string uses 24 series-connected 2V cells. Capacity and autonomy must be calculated for the actual discharge rate and end voltage.
OPzV Discharge & Performance Curves
Manufacturer reference curves for OPzV tubular gel cells. At 20°C, the supplied chart shows cell voltage over time at discharge rates of 1CA, 0.5CA, 0.25CA, 0.1CA and 0.05CA. Other charts cover float life by temperature, self-discharge, cycle life by depth of discharge, capacity by temperature, charging performance and charge voltage by temperature. Actual results vary by model and operating conditions.
