Pro Tips for Choosing Wisely

1. Match amperage to battery capacity: Ideally, use a charger delivering ~10% of your battery’s amp-hour rating for optimal charging.
2. Multi-stage charging is best: Look for bulk, absorption, float, and desulfation modes to extend battery life.
3. Charger must match battery type: AGM, flooded-cell, gel, and lithium batteries all have different charging needs—make sure your charger specifies compatibility.
4. Marine-specific build quality matters: Waterproofing, vibration-resistance, and compliance with marine safety standards ensure longevity.
