NOVELTY - An analyzing apparatus comprises storage unit(s) (radio frequency identification (RFID) TAGS) designed to be integrated in vehicle batteries (BAT) and to store data on maintenance operations and identification information; measuring instrument(s) (TST), designed to make measurements of characteristic parameters of the batteries; and read/write (R/W) devices (RFID R/W) connected to measuring instruments and designed to read and write the data from/in the storage unit(s).    USE - Apparatus for analyzing the state of maintenance and efficiency of batteries, especially for industrial and/or commercial vehicles (claimed).    ADVANTAGE - The apparatus maximizes the working life of the battery components, minimizes the replacements of the batteries for reasons of inadequate maintenance, reduces the cases of the vehicle being out of running order owing to unforeseen faults of the battery, reduces the cases of inefficiency and risks of unusability, provides diagnostic apparatus that identifies whether the battery is still compatible with the vehicle characteristics, feedbacks to design department for product improvements, feedbacks to the user to correct any possible energy abuse of the vehicle; reduces costs for the user due to the vehicle being out of running order; and reduces the environmental impact owing to optimization of the use of the batteries.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a battery, especially for industrial and/or commercial vehicles comprising an integrated storage unit (i.e. transponder), and designed to store data on maintenance operations and information on identification of the battery and/or the vehicle;    (2) a computer program comprising program-coding mechanism designed to execute the method for analyzing the state of maintenance and efficiency of batteries when the program is run on a computer; and    (3) a computer-readable mechanism comprising a recorded program, and program-coding mechanism designed to execute the method for analyzing the state of maintenance and efficiency of batteries when the program is run on a computer.    DESCRIPTION OF DRAWING(S) - The drawing is a block diagram of a system for analyzing the state of maintenance and efficiency of batteries.
