Maintenance Tips
-
Install the HUSKY 2 Kit in a cool, dry, and well-ventilated area to ensure stable 12V performance and prolong battery life.
-
Regularly inspect terminals, connectors, and wiring for looseness, corrosion, or damage to maintain safe and reliable operation.
-
Clean battery casings with a soft, dry cloth to remove dust and prevent heat buildup.
-
Protect the kit from direct sunlight, moisture, and extreme temperatures to preserve cell health and efficiency.
-
Avoid deep discharges; monitor state of charge to maintain long-term capacity and performance.
-
For long-term storage, maintain batteries at 50–60% charge and disconnect from all loads.
