Key Takeaways

  • Keep your pool cleaner's battery in a cool, dry spot. The temperature should stay between 50°F and 77°F to avoid damage.
  • Fully charge the battery before storing it. During winter, keep the charge between 40% and 60% for best performance.
  • Check the battery every month for swelling or leaks. Use a case to protect it from getting damaged.

Risks of Improper Lithium Battery Storage

 

Battery degradation from extreme temperatures

Lithium batteries are sensitive to temperature changes. When exposed to extreme heat or cold, their chemical structure weakens. This leads to reduced capacity and shorter battery life. If you store your robotic pool cleaner in a garage or shed that isn’t temperature-controlled, the battery may degrade faster.

Tip: Keep the storage area between 50°F and 77°F to protect the battery from temperature-related damage.

Capacity loss due to overcharging or undercharging

Improper charging habits harm lithium batteries. Overcharging causes the battery to heat up, which damages its internal components. Undercharging, on the other hand, leaves the battery in a low-energy state that accelerates capacity loss.

To avoid these issues, monitor the battery’s charge level before storage. Aim for a charge between 40% and 60%. This range keeps the battery stable during long periods of inactivity.

  • What happens if you overcharge?
    • Reduced battery efficiency
    • Increased risk of overheating
  • What happens if you undercharge?
    • Permanent capacity loss
    • Difficulty recharging in the future

Safety concerns like leaks or swelling

Improper storage increases the risk of battery leaks or swelling. These issues occur when the battery’s internal pressure builds up due to physical damage or exposure to extreme conditions. Swollen batteries can rupture, while leaks release harmful chemicals.

Warning: Never store batteries near sharp objects or in humid environments. Use a protective case to prevent physical damage.

By understanding these risks, you can take steps to ensure your robotic pool cleaner’s battery remains safe and functional during winter storage.

Winter Maintenance List: 6-Step Rule for Lithium Battery Storage of Robot Swimming Pool Cleaners

Proper storage of lithium batteries during winter ensures your robotic pool cleaner remains efficient and safe. Follow this Winter maintenance list: 6-step rule for lithium Battery Storage of Robot Swimming pool cleaners to protect your investment and extend its lifespan.

Step 1: Fully charge the battery before storage

Before storing your robotic pool cleaner, charge the battery to 100%. A fully charged battery prevents deep discharge, which can damage its internal components. This step ensures the battery remains in good condition during the initial phase of storage.

Tip: Use the manufacturer-recommended charger to avoid overcharging or undercharging.

Step 2: Store in a cool, dry, and temperature-controlled area

Choose a storage location that is free from moisture and maintains a stable temperature. Lithium batteries are sensitive to humidity and temperature fluctuations. A cool, dry environment minimizes the risk of corrosion and degradation.

  • Ideal storage conditions:

Temperature Range

Humidity Level

50°F to 77°F

Below 50%

Avoid storing the battery in basements or garages prone to dampness.

Step 3: Maintain a charge level of 40-60% during storage

After the initial full charge, discharge the battery to a level between 40% and 60%. This range is optimal for long-term storage. A fully charged battery may experience stress over time, while a completely discharged one risks permanent damage.

Note: Check the battery’s charge level every month and recharge it if it drops below 40%.

Step 4: Use protective cases to prevent physical damage

Store the battery in a protective case to shield it from accidental impacts or scratches. Physical damage can compromise the battery’s safety and performance. A sturdy case also prevents exposure to dust and debris.

Warning: Never place heavy objects on top of the battery, even when it’s in a case.

Step 5: Avoid exposure to freezing or excessively hot conditions

Extreme temperatures can harm lithium batteries. Freezing conditions slow down the chemical reactions inside the battery, while excessive heat accelerates degradation. Keep the battery away from windows, heaters, or uninsulated areas.

Reminder: If you live in a region with harsh winters, consider using a climate-controlled storage unit.

Step 6: Check battery health monthly during storage

Inspect the battery at least once a month. Look for signs of swelling, leaks, or corrosion. Test the charge level and recharge if necessary. Regular checks help you identify potential issues early, ensuring the battery remains safe and functional.

Pro Tip: Use a multimeter to measure the battery’s voltage and confirm its health.

By following this Winter maintenance list: 6-step rule for lithium Battery Storage of Robot Swimming pool cleaners, you can protect your battery from damage and ensure your robotic pool cleaner operates efficiently when spring arrives.

Common Mistakes to Avoid

 

Leaving batteries fully discharged for long periods

One of the most common mistakes is storing lithium batteries in a fully discharged state. When a battery remains completely drained for an extended time, it can enter a deep discharge state. This condition makes it difficult or even impossible to recharge the battery later.

Tip: Always charge your battery to at least 40% before storing it. This ensures the internal components remain active and prevents irreversible damage.

Leaving the battery discharged not only shortens its lifespan but also reduces its efficiency. You may notice your robotic pool cleaner struggling to hold a charge when spring arrives.

Storing in damp or humid environments

Humidity is a silent enemy of lithium batteries. Storing your battery in a damp or humid area can lead to corrosion of its internal components. Over time, this corrosion weakens the battery and increases the risk of leaks or swelling.

  • Avoid these storage locations:
    • Basements prone to flooding
    • Garages with poor ventilation
    • Outdoor sheds exposed to weather changes

Reminder: Choose a dry, temperature-controlled space to keep your battery safe from moisture-related damage.

Ignoring battery health before spring use

Many people forget to check their battery’s condition before using it again in spring. This oversight can lead to unexpected failures or safety hazards. A neglected battery may show signs of swelling, leaks, or reduced capacity, all of which can affect your robotic pool cleaner’s performance.

Pro Tip: Inspect your battery a month before pool season begins. Look for physical damage and test its charge level. Addressing issues early ensures your pool cleaner is ready to go when you need it.

By avoiding these mistakes, you can protect your battery and enjoy a hassle-free pool cleaning experience year after year.

Long-Term Benefits of Proper Storage
