Century Deep Cycle Flooded batteries are constructed using thickerplates, specialist lead calcium alloys and denser active material, towithstand repeated recharge and discharge cycles.
Premium grade rawmaterials and electrolyte ensures reliable deep cycle performance inrecreational applications.Product DimensionsCharging ProcedureContinued overleafCorrect charging is one of the most important factorswhen using deep cycle lead acid batteries. Following adischarge, the battery should be fully charged in a wellventilated area.Charging at constant voltage is the most suitable methodfor charging a deep cycle battery. Figure A (overleaf)shows the typical charging characteristic of a deepcycle battery that has been discharged to 80% depth ofdischarge, then charged with a constant voltage chargerat 2.40vpc with the initial charging current controlled at0.1CA.The charging current is maintained at this level untilthe battery voltage reaches 2.40vpc. At this point, theconstant voltage phase starts and charging currentgradually drops. The charging process is terminated whenthe charging current has dropped below 2% of nominalcapacity, or total charging time of 24 to 36 hours.It is recommended that charging should be stopped if theelectrolyte temperature reaches 50ºC. It can recommencewhen the temperature has dropped back below 40ºC.In an application where multiple batteries are employed,there is also a need to provide an equalisation chargeonce a month. This ensures that every cell in the batterybank is fully charged and balanced. This is completedby fully charging the battery, then extending the chargingtime by another 12 to 24 hours at 2.40vpc.To maintain optimum performance, it is recommendedthat the battery is recharged at least once per monthwhile in storage.
