4. General Setup & Operation
4.1 Initial Charging
It is recommended to fully charge the battery before its first use. Use a charger compatible with the battery type (SLA for 6V, LiFePO4 for 12.8V) and voltage. Refer to the charger's instructions for proper charging procedures.
4.2 Connection
- Ensure all equipment is turned off before connecting the battery.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of your device/system.
- Connect the negative (-) terminal of the battery to the negative (-) terminal of your device/system.
- Ensure all connections are secure to prevent arcing or poor performance.
4.3 Discharging
Avoid over-discharging the battery. While both batteries offer protection against deep discharge, consistent over-discharging can reduce overall lifespan. Monitor your device's power requirements and battery voltage.
5. Maintenance & Storage
5.1 Maintenance
Both Miady batteries are designed to be maintenance-free. Regularly inspect terminals for corrosion and ensure connections are tight. Keep the battery clean and free from dust and debris.
5.2 Storage
- Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
- For the 12.8V LiFePO4 battery, store at approximately 75% capacity and recharge every 6 months if not in use.
- Do not store above 60°C (140°F).
6. Safety Precautions
Adhere to the following safety guidelines to prevent injury or damage:
- Do Not Short Circuit: Avoid connecting the positive and negative terminals directly.
- Do Not Disassemble: Do not attempt to open or modify the battery casing.
- Temperature: Do not expose batteries to temperatures above 50°C (122°F) for SLA batteries or 60°C (140°F) for LiFePO4 batteries, or incinerate.
- Sparks and Flames: Keep batteries away from sparks, open flames, and heat sources.
- Ventilation: Ensure adequate ventilation when charging SLA batteries.
- Recycling: Batteries must be recycled or disposed of properly according to local regulations.
- Physical Damage: Do not crush, mutilate, or reverse polarity.
- Children: Keep batteries out of reach of children.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incorrect charger, loose connections, faulty charger, battery deeply discharged (SLA) | Verify charger compatibility and connections. Test charger. For SLA, try a specialized desulfation charger if deeply discharged. LiFePO4 BMS may prevent charging if voltage is too low; consult support. |
| Battery not holding charge | Aging battery, excessive discharge, internal fault | Ensure proper charging. Avoid over-discharging. If battery is old, replacement may be necessary. |
| Device not powering on | Battery discharged, incorrect connection, faulty device | Charge battery. Check all connections. Test battery with another device or test device with another power source. |
