Warnings about explosive gases generated by lead-acid batteries during operation and the importance of following instructions.
Instructions to follow to reduce the risk of battery explosions, including following marked instructions.
Never smoke or allow sparks or flames in the vicinity of the battery or engine.
Cautions regarding charger use, including intended battery types and avoiding damage to property or persons.
Guidelines for safely handling the charger's cord and plug to prevent damage and electric shock.
Avoid operating the charger in closed-in areas or restricting ventilation.
Ensure someone is within voice range or close enough for aid when working with lead-acid batteries.
Keep plenty of fresh water and soap nearby for cases of battery acid contact.
Wear complete eye protection and clothing protection, avoid touching eyes while working near batteries.
Immediate washing procedures for skin/clothing contact with battery acid, and eye contact with water.
Do not drop metal tools on batteries as it might cause sparks or short-circuit damage.
Remove all metal items (jewelry) when working with lead-acid batteries to prevent short circuits.
Remove grounded terminals first and ensure vehicle accessories are off to prevent arcs during charging.
Ensure the area around the battery is ventilated during charging to disperse explosive gases.
Clean battery terminals carefully, ensuring corrosion does not contact eyes.
Add distilled water to unsealed batteries and follow instructions for sealed batteries.
Determine battery voltage and ensure it matches the charger's output rating.
Place charger as far from battery as DC cables permit, not directly above or below the battery.
Never allow battery acid to drip on the charger when reading gravity or filling battery.
Do not operate the charger in a closed-in area with poor ventilation.
Do not set a battery on top of the charger.
Connect/disconnect DC clips only after removing AC cord; never allow clips to touch each other.
Steps for connecting the charger to a battery installed in a vehicle to avoid sparks.
Stay clear of moving engine parts like fan blades, belts, and pulleys during connection.
Check battery post polarity; positive posts may have a larger diameter than negative posts.
Determine which battery post is grounded to the chassis for correct connection.
Connect red clip to positive post, black clip to chassis of a negative-grounded vehicle.
Connect black clip to negative post, red clip to chassis of a positive-grounded vehicle.
Connect via a permanently mounted eyelet Lead SAE connector if applicable.
Connect the charger's AC supply cord to an electric outlet.
Sequence for disconnecting: AC cord, chassis clip, then battery clip.
Check battery post polarity before connecting when the battery is outside the vehicle.
Attach an insulated battery output cable to the negative battery post.
Connect the positive (red) clip from the charger to the positive battery post.
Connect the negative (black) clip to the free end of the cable, away from the battery.
Position yourself and the cable end away from the battery during final connection.
Connect the charger AC supply cord to an electric outlet.
Disconnect in reverse order of connection, breaking the first connection far from the battery.
Marine batteries must be removed and charged on shore unless special equipment is used.
Charger is automatic; monitors battery and switches to storage mode when fully charged.
How to connect the red positive and black negative leads to the battery terminals.
Periodically check water levels for lead-acid batteries left connected long-term.
Charger has spark-free and reverse polarity protection; avoid clip contact.
Charger requires at least 2V from battery; correct polarity is needed for charging.
Red 'Reverse Polarity' light flashes if connected incorrectly; re-connect properly.
Avoid repeatedly plugging/unplugging charger; wait 1 minute after unplugging.
Formula and example for estimating battery charge time based on capacity and current.
Recommendation to charge only one battery at a time.
Charger requires >2V to start; a bad battery indicator flashes if below this.
Procedure to momentarily jump a <2V battery to a charged one to initiate charging.
Batteries below 9V after rapid discharge may be defective.
Timer protects marginal batteries from overcharging; switches to float mode if charged within 72 hours.
