After 3 minutes, the ENGINE START LED will stop blinking and will light continuously, indicating that another crank cycle can be started. The digital display will change from displaying the countdown back to displaying the battery voltage. The CHARGING LED will then be lit. ENgiNE STARTiNg NOTES: • If

There are some important facts to keep in mind when charging a battery. • When the display indicates 77% charged, the battery has been charged enough to start most vehicles and has already been charged as much as by many other battery chargers. • When the display indicates 85% charged, the battery has already been charged at least as much as by most other battery chargers. • The battery % shown in tester mode is an estimate based on
