1 The person responsible for carrying out the maintenance should decide whether, for the sake of simplicity,
the entire internal battery pack should be changed as a precautionary measure, or if a battery test should be
performed first. If the battery test results in a capacity < 80 %, the entire battery pack (optionally with or with -
out PCB) should be changed. At a capacity of ≥ 80 %, the batteries do not require changing.
