Your underwater scooter is only as reliable as its battery. Proper care ensures longer lifespan, better performance, and safer adventures. Whether you’re a casual explorer or a frequent diver, these essential do’s and don’ts will help you maximize your battery’s life and avoid costly mistakes.

✅ The Do’s: Best Practices for Battery Maintenance
1. Charge Correctly After Every Use
Recharge the battery soon after use, even if it’s not fully drained.

Use only the original charger to prevent overcharging or voltage issues.

Avoid storing the battery at low charge, which can cause long-term damage.

2. Store at the Optimal Charge Level
For long-term storage, keep lithium batteries at 40-60% charge.

Store in a cool, dry place (ideally between 50°F–77°F / 10°C–25°C).

Check the charge every 1-2 months if unused for extended periods.

3. Rinse After Saltwater Exposure
Saltwater can corrode battery terminals—always rinse with fresh water after use.

Dry the battery and connectors thoroughly before storage.

4. Regularly Check for Wear & Damage
Inspect for swelling, leaks, or cracks—replace immediately if found.

Clean corroded contacts gently with a soft brush or cloth.

5. Follow the Manufacturer’s Guidelines
Different battery types (Li-ion, LiPo, etc.) have specific care requirements.

Always refer to the user manual for charging cycles and safety tips.

❌ The Don’ts: Mistakes That Shorten Battery Life
1. Don’t Overcharge or Leave Plugged In Indefinitely
Overcharging degrades battery cells and can be a fire risk.

Use a smart charger if available to prevent overcharging.

2. Don’t Fully Drain the Battery
Deep discharges weaken lithium batteries over time.

Recharge when the battery reaches 20-30% remaining.

3. Don’t Expose to Extreme Heat or Cold
High temperatures (above 95°F / 35°C) accelerate wear.

Never charge a cold battery—let it warm to room temperature first.

4. Don’t Use a Damaged Battery
A swollen or leaking battery is dangerous—replace it immediately.

Never attempt to repair or modify a lithium battery yourself.

5. Don’t Ignore Performance Drops
If runtime decreases significantly, the battery may need replacement.

Test voltage periodically if your scooter supports diagnostics.
