Attempt to start the engine in short bursts (5 seconds on, 45 seconds off) to prevent the charger from overheating. 3. Important Safety Precautions Working with lead-acid batteries involves risk of explosion and chemical burns. Ventilation : Always charge in a well-ventilated area, as batteries release explosive hydrogen gas during the process. Eye Protection : Wear safety glasses and protective clothing. No Sparks : Never smoke or allow open flames near the battery while charging. Avoid Overcharging : Use a voltmeter or hydrometer to check the state of charge.
