Q: Does the charger stop automatically when the battery is fully charged?
A: Yes! The charger features an automatic shut-off function that stops the charging process as soon as the battery reaches full capacity. This protects the battery from overcharging and extends its overall lifespan.
Q: What does the pulse repair function do?
A: The pulse repair function sends controlled electrical pulses to help recondition lead-acid batteries that have been deeply discharged or left unused for a long time — conditions that can reduce a battery's ability to hold a charge. This feature can help restore usable capacity to batteries that might otherwise seem unusable.
Q: How do I connect the charger safely?
A: Always connect the red clip to the battery's positive (+) terminal and the black clip to the battery's negative (–) terminal. The built-in reverse polarity protection will alert you if the clips are connected incorrectly, helping prevent damage to the charger or battery.
