Frequently Asked Questions
Q: What types of batteries is this 12V charger compatible with?
A: This charger is designed for 12V lead acid batteries only — including wet (flooded), dry (AGM), and gel types — with a capacity range of 4AH to 20AH. It is not compatible with lithium batteries of any kind.
Q: What does the pulse repair function do?
A: The pulse repair function sends controlled electrical pulses through the battery to help break down sulfation on the battery plates. This process can help restore charge-holding capacity in lead acid batteries that have become underperforming due to prolonged storage or repeated deep discharge.
Q: Is this charger safe for motorcycle and car batteries?
A: Yes. This charger is suitable for 12V lead acid batteries commonly found in cars, motorcycles, trucks, ATVs, and small engine equipment. Always ensure the battery voltage and type match (12V lead acid, 4AH–20AH) before use, and connect clamps correctly — red to positive (+) and black to negative (−).
Q: What input voltage does this charger require?
A: This charger requires a 220V AC power supply. Please ensure your outlet matches this voltage before use.
