4.Low Self Discharge Because of the use of lead-calcium grids alloy, RITAR batteries have low self discharge and reliable performance. In room temperature, self discharge ratio per month of RITAR battery is about 3% of the battery capacity. -
Page 6: Battery Charge, Discharge & Life
VRLA batteries, because equalizing charge will increase water loss and grid corrosion, which will cause early failure. Equalizing charge requirements for RITAR battery are as follows: ※ The equalizing charging voltage is related to the ambient temperature. The equalizing charging voltage of single cell is 2.35v-2.45v/cell at 25 ℃. - Page 7 5. Charge Curve of Cycle Use The batteries for cycle service adopt the constant Charge Characteristic Curve of Cycle Use voltage but limited current method. At 20℃ ~25℃ , 2.42 2.60 the charge voltage of GEL series battery is 2.40V Charge Voltage 2.36 2.40...
