  1. Charge Regularly, Don’t Wait Too Long
    Don’t let the battery sit discharged for long periods. A quick recharge after each use keeps it healthier and extends its life.

  2. Avoid Deep Discharges Whenever Possible
    Try not to run the battery completely flat. Keeping the charge above 30–40% helps reduce stress on the cells.

  3. Use the Right Charger
    Always pair the battery with a high-quality, compatible charger (ideally with smart charging features). This ensures stable charging without overcharging.

  4. Keep It Clean & Dry
    Wipe the terminals occasionally and check for dirt or corrosion. Clean connections allow smoother power flow and prevent energy loss.

  5. Mind the Temperature
    Extreme heat or cold shortens battery life. Store and operate it in a cool, dry place whenever possible.

  6. Don’t Overload It
    Respect the battery’s rated capacity. Connecting too many devices or drawing higher current than recommended can damage the plates.

  7. Top Off Before Storage
    If storing for weeks or months, give it a full charge first and recharge it every 1–2 months to avoid deep self-discharge.

  8. Gentle First Use
    For new batteries, a few shallow charge/discharge cycles help them “wake up” and perform at their best.

  9. Use Original Accessories
    Stick with the manufacturer-recommended terminals, cables, and mounting hardware to avoid unnecessary stress or vibration damage.

  10. Listen to the Battery
    If you notice it charging too slowly, losing power quickly, or heating up, it’s telling you something’s wrong. Take action early to prevent permanent damage.

1. Safety First

  • Always wear protective gloves and goggles when handling the battery.

  • Keep sparks, flames, and cigarettes away from the battery.

  • Work in a well-ventilated area to avoid gas buildup.

2. Unpacking & Inspection

  • Carefully remove the battery from its packaging.

  • Check for cracks, leaks, or loose terminals.

  • Ensure the voltage is within the normal open-circuit range (13.0–13.4V).

3. Installation Steps

  1. Switch Off Power – Make sure the equipment is turned off before connecting.

  2. Identify Terminals – Positive terminal (+) is usually red; negative (–) is black.

  3. Secure the Battery – Place the battery in a stable, upright position.

  4. Connect Cables – Connect the positive cable first, then the negative.

  5. Tighten Screws – Use M6×16 screws to fasten terminals securely, avoiding over-tightening.

  6. Check Connections – Ensure no loose wires or exposed metal.

4. Charging Guidelines

  • Use a compatible smart charger.

  • Floating Charge: 13.8V

  • Cycle Charge: 14.7V

  • Avoid overcharging or leaving the battery fully discharged.

  • Charge in a cool, ventilated environment.

5. Usage Tips

  • Do not exceed the maximum discharge current (375A).

  • Avoid complete deep discharges; recharge when capacity reaches ~30%.

  • Keep terminals clean and corrosion-free.

  • Operate between –20°C to 40°C for best performance.

6. Storage & Maintenance

  • Store fully charged if not in use.

  • Recharge every 1–2 months during storage.

  • Residual capacity after self-discharge:

    • 30 days: ~90%

    • 60 days: ~85%

    • 90 days: ~80%

    • 180 days: ~82%

  • Keep away from direct sunlight, heat, and moisture.

7. Troubleshooting

  • Battery drains quickly → Recharge fully; check for overload.

  • Slow charging → Verify charger output and connections.

  • Corrosion on terminals → Clean gently with baking soda solution and dry thoroughly.

Frequently Asked Questions (FAQ)

How often should I recharge the battery when not in use?

Even when not in use, this battery self‑discharges. It’s best to recharge it at least every 3 months to keep it healthy

Can it be stored in any orientation?

Yes! It’s a sealed VRLA type, so it can be placed sideways, upsidedown—no worries about leaking

What temperature range works best?

The ideal ambient temperature is around 20–25 °C. High heat or extreme cold can shorten its life

What depth of discharge is safe?

For long life, try not to drain more than 50%—deeper discharges stress the battery and may cause permanent damage

What’s the difference between float charge and cycle charge?

A float charge keeps the battery topped up (great for standby use), while a cycle charge fully charges and discharges it regularly—each suits different use cases

How long can I expect it to last?

With proper care, this battery typically lasts 3–5 years, sometimes even longer in ideal conditions

Can sulfation be reversed if the battery has been left undercharged?

Sadly, no reliable method exists—once sulfation sets in, it can’t realistically be reversed. Prevention is the best cure

How much does it self‑discharge over time?

Expect gradual loss: up to 1% per day—so even unused batteries lose power over time

How simple is charging this battery?

Very simple! A consistent charger set at 13.6–13.8 V works great—even a basic float trickle charger does the job

Is this battery still a good choice compared to newer types?

Absolutely! Although it’s an older tech, it delivers high surge power, is affordable, and still widely trusted for motors, backup systems, and vehicles
