Accumulator is one of motor vehicles and mobile machines elements, which good technical condition determines the availability of the machine. Even when appropriate method of using is applied the available accumulator capacity gradually decreases. The actual technical condition of the accumulator can be objectively found out by carrying out the simplificated starting test, which allows to carry out the accumulator preventive maintenance as well. The test is simple, quick and objective and is therefore suitable for both detail inspection and orientation survey of the accumulator. The paper brings results of verification of the simplificated starting test methodology. The verification was carried out for common lead-acid starting accumulators, which were tested using suggested simplificated starting test and standard capacity test.

The paper briefly describes and demonstrates the possibilities of processing, utilization and evaluation of computer maintenance system based data with the aim of increasing of quality and effectiveness of maintenance system. The data in the example were obtained from machine works which uses computer maintenance management for last three years. The presented example is focused on evaluation of maintenance records from point of view of maintenance management system. An emphasis is put on continuous corrections of the maintenance system resulting in its improvement and elimination of weak points.
