TECHNICAL SPECIFICATIONS TRACTIONELEMENTS PzS, PzB MATERIALS The Self-discharge of traction batteries, at temperature +300C after being in fully charged condition 30 days, should be not more than 1 % Number of Charging - discharging cycles 1200 - when following the instructions presented by the manufacturer. The capacity of the traction batteries is considered to be true for the temperature of 300C. If during the testing of the capacity the degrees are different from 300C, the capacity may be equaled to 300C using the following formula: Tcp. -Average temperature during the testing. For practical purposes the true capacity could be calculated by using the following way: - raising the temperature above 300C the measured capacity will be increased with 0,6% per every degree. - decreasing the temperature under 300C the measured capacity will be decreased with 0,6% per every degree.
