How to Use the Fusion 100Ah Lithium Battery
Step 1: Install in a Suitable Position
Mount the battery securely in a dry, ventilated area with minimal vibration.
Step 2: Connect Terminals Properly
You need to attach the positive terminal (+) first, then the negative (-). Use high-quality connectors for best results.
Step 3: Charge with Compatible Equipment
Use a standard 3-Stage AGM smart charger or alternator that supports lithium batteries.
For best results and to maximise the lifespan of your Fusion battery, we recommend using a Smart Lithium Battery Charger specifically designed for fast, safe, and efficient lithium charging.
Step 4: Monitor Regularly
Check charge levels before storage or after long use. Recharge immediately if voltage drops below recommended levels.
Step 5: Conduct Periodic Inspections
While maintenance-free, occasional checks for tightness of terminals and general condition will help maintain top performance.
