The software update (EL-50332-SWV9) addresses how the EV Battery Depowering Tool’s internal 10-hour time interrupts the balancing process after replacing a battery section. The current tool automatically interrupts the balancing process at 10 hours, which may cause lost time for balancing procedures during some repairs. As part of the software update, the internal 10-hour timer now shows on-screen continuation instructions, helping to reduce unnecessary interruptions to longer balancing procedures.

In addition, the software update contains all previously introduced relevant updates for the EV Battery Depowering Tool.
