The data shown are nominal and should not be construed as maximum or minimum values for specification or final design.
Data for this product type may vary from that shown herein.
Typical battery life is based upon a baseline operating
temperature of 80°F / 27°C. Temperature increases
of 15°F / 10°C over the baseline will cause the
battery’s rate of internal chemical reactions to double
– something that will reduce battery life due to the
accelerated deterioration of internal components.
Please contact Crown Battery to discuss any minimal
requirements for battery life when operating batteries
in temperatures greater than 80°F / 27°C.
Constant Voltage Charging
CYCLE CHARGE: 2.40 - 2.47 V Temperature Correction: +/- 3 mV / °C
FLOAT CHARGE: 2.20 V Recommended Charge Current: 300 Amperes
Maximum Charge Current*: 420 Amperes
CYCLIC CHARGING
Cyclic applications exceeding 50% depth-of-discharge may require different charger voltage set points.
Contact Crown Battery to discuss your application requirements. * Specification requires use of all terminals.
Proper charging of renewable power batteries is essential
to optimize the performance and life of the batteries. To
ensure dependability and life batteries should be charged
after each discharge period. Regular monitoring of battery
voltage condition is recommended to verify system recharging
performance. Refer to the following table for additional charge
control setting information.
