The Do’s and Don’ts of Lipo Battery Storage: Tips to Avoid Common Mistakes

Proper storage of Lithium Polymer (LiPo) batteries is crucial to maintaining their longevity, safety, and performance.

To ensure you avoid common mistakes, follow these do’s and don’ts when storing your LiPo batteries:

Do’s

• Store at proper charge levels: Maintain a storage charge of around 50% (3.8V per cell) for your LiPo batteries. This helps prevent the battery from becoming overcharged or over-discharged, which can damage the cells and reduce battery life.

• Use a LiPo-safe storage container: Invest in a fire-resistant container or LiPo safety bag to store your batteries. These specialized containers help minimize the risk of fire and protect your belongings in case of a battery failure.

• Store in a cool, dry place: Keep your batteries in an environment with a temperature between 40°F (5°C) and 70°F (21°C). Avoid exposure to direct sunlight or high humidity, which can negatively impact the battery’s performance and lifespan.

• Inspect your batteries regularly: Before and after storage, check your batteries for any signs of damage, swelling, or leaks. If you notice any issues, dispose of the battery properly and replace it with a new one.

• Label your batteries: Use a label or marker to indicate the date of purchase and storage voltage on each battery. This will help you keep track of their age and prevent you from accidentally overcharging or over-discharging them.

Don’ts

• Don’t store fully charged or fully discharged batteries: Storing LiPo batteries at full charge or full discharge can damage the cells, reducing their lifespan and performance.

• Don’t store batteries near flammable materials: Keep your LiPo batteries away from paper, fabrics, or other flammable materials to minimize the risk of fire in case of a battery failure.

• Don’t store damaged batteries: If your battery is damaged, swollen, or leaking, do not store it. Instead, dispose of it safely and replace it with a new one.

• Don’t store batteries in airtight containers: Although it’s essential to use a fire-resistant container, avoid using airtight containers for storing LiPo batteries. In case of a fire, airtight containers can trap gas released by the battery, potentially causing an explosion.

• Don’t store batteries together with metal objects: Keep your batteries separate from any metal objects like coins, keys, or tools, as these can cause short circuits or puncture the battery, leading to a fire or explosion.

Maintaining Your Lipo Battery during Long-Term Storage: Periodic Checkups and Care

When it comes to long-term storage of LiPo (Lithium Polymer) batteries, proper care, and maintenance are essential to ensure their safety, longevity, and optimal performance.

LiPo batteries are commonly used in RC vehicles, drones, and other electronic devices.

Following these guidelines will help you take care of your LiPo batteries during periods of extended storage.

Storage Voltage and Temperature

Ensure that the LiPo battery is stored at the recommended storage voltage, typically around 3.8 volts per cell.

A fully charged LiPo battery will have a voltage of 4.2 volts per cell. Use a quality balance charger to discharge the battery to the recommended storage voltage.

Store the LiPo battery in a cool, dry place, ideally at a temperature between 15-25°C (59-77°F). Avoid direct sunlight or extreme temperature fluctuations.

Periodic Checkups

It’s crucial to inspect your LiPo batteries periodically during long-term storage, ideally once a month.

Check the battery’s voltage using a multimeter or a battery checker to ensure that it remains within the recommended storage voltage range.

If the voltage has drifted too far from the recommended storage voltage, recharge or discharge the battery accordingly using a balance charger to bring it back to the ideal level.

Physical Inspection

During your periodic checkups, also examine the battery for any signs of physical damage, such as puffing, swelling, or leakage.

If you notice any abnormalities, it’s time to replace the battery. Never attempt to use a damaged LiPo battery, as it may pose a safety risk.

Storage Container

Use a fireproof and explosion-proof container, such as a LiPo-safe bag or an ammunition box, for storing your LiPo batteries.

This precaution can help contain a fire if a battery fails and ignites during storage.

Charge before Use

After a long period of storage, ensure that the battery is fully charged before using it on your device.

A fully charged LiPo battery will have a voltage of 4.2 volts per cell. Charging the battery before use helps to ensure optimal performance and battery life.

Cycle the Battery

If your LiPo battery has been stored for more than three months, it’s a good idea to cycle it before use.

This process involves discharging the battery to a safe level and then fully charging it again. Cycling the battery can help rejuvenate the cells and improve overall performance.
