AGM (Absorbent Glass Mat) batteries are sealed lead-acid batteries designed for high performance, deep-cycle capability, and maintenance-free operation. Proper care ensures longevity and reliability. This manual provides essential guidelines for safe handling, charging, storage, and troubleshooting.
Ventilation: AGM batteries are valve-regulated but may emit gases under extreme conditions. Install in a well-ventilated area.
Temperature: Avoid exposure to temperatures above 50°C (122°F) or below -20°C (-4°F).
Short Circuits: Use insulated tools and avoid placing metal objects on terminals.
Eye/Skin Protection: Wear gloves and goggles when handling. If electrolyte leaks, neutralize with baking soda and rinse with water.
Fire Safety: Keep away from open flames or sparks—hydrogen gas may be produced during charging.
Mounting: Secure the battery upright to prevent vibration damage. Do not invert or tilt beyond 45°.
Connections:
Clean terminals with a wire brush if corroded.
Connect positive (+) terminal first, then negative (-). Tighten securely to avoid arcing.
Apply anti-corrosion spray or grease on terminals.
Voltage Check: Ensure system voltage matches battery voltage (e.g., 12V battery for 12V system).
Charger Type: Use a smart charger compatible with AGM batteries. Avoid old chargers designed for flooded batteries.
Voltage Limits:
Float Charge: 13.5–13.8V (for maintenance)
Cycle Use: 14.4–14.8V (for active charging)
Current: Charge at 0.1C–0.3C (e.g., 2A–6A for a 20Ah battery).
Temperature Compensation: Reduce voltage by 0.03V/°C if charging above 25°C (77°F).
Do Not Overcharge: Disconnect when fully charged to prevent drying out the electrolyte.
Long-Term Storage:
Charge fully before storage.
Store in a cool, dry place (ideally 10–25°C / 50–77°F).
Recharge every 3–6 months to prevent sulfation.
Regular Checks:
Inspect terminals for corrosion monthly.
Check voltage periodically (healthy range: 12.8–13.2V at rest).
Keep battery case clean and dry.
Depth of Discharge (DoD): For longest lifespan, avoid discharging below 50% DoD. Deep discharges below 80% may reduce cycle life.
Voltage Cut-off: Stop using if voltage drops below 10.5V (for 12V battery) under load.
Avoid Continuous Low Charge: Recharge immediately after use.
| Issue | Possible Cause | Solution |
|---|---|---|
| Battery won’t hold charge | Sulfation, old age, undercharging | Try equalization charge (if supported); replace if aged. |
| Swollen/bulging case | Overcharging, excessive heat | Stop use; check charger settings; replace battery. |
| Low voltage output | Deep discharge, poor connections | Recharge with AGM-compatible charger; tighten terminals. |
| Terminal corrosion | Electrolyte leakage, moisture | Clean with baking soda solution; apply anti-corrosion gel. |
AGM batteries are recyclable. Do not dispose of in regular trash.
Return to authorized recycling centers or battery retailers.
Follow local regulations for hazardous waste handling.
Warranty may be voided by:
Physical damage or improper installation.
Overcharging, deep discharging, or use in extreme temperatures.
Unauthorized modification.
