Store the batteries in a protective case or a designated storage area where they won't be jostled or dropped. Keep them away from sharp objects and ensure that they are not subjected to physical stress, which could lead to internal damage or leaks.
Power tool batteries are the heart of cordless tools, offering the freedom and flexibility to work efficiently without being tethered to a power source. Whether you use them every day or occasionally, proper storage is essential to ensure that your batteries remain in top condition and deliver consistent performance over time. Improper storage can shorten battery life, reduce efficiency, and lead to potential safety risks. As a leading power tool battery manufacturer, Semitech understands the importance of maintaining your batteries. In this article, we’ll share expert tips on how to properly store power tool batteries to extend their lifespan and performance.
Temperature plays a critical role in battery health, and storing batteries in extreme temperatures can cause irreversible damage. According to industry experts, the optimal storage temperature for most power tool batteries is between 40°F and 70°F (4°C to 21°C).
Avoid Extreme Heat: High temperatures, particularly over 100°F (38°C), can cause the battery cells to degrade rapidly. Excessive heat can also increase the risk of overheating, which may lead to dangerous situations such as battery leakage or even fires.
Avoid Freezing: On the other hand, freezing temperatures can cause the electrolyte inside the battery to freeze, leading to permanent damage. It’s crucial to store your batteries in an environment where temperatures are consistently within the recommended range.
For most cordless tool batteries, including lithium-ion and nickel-cadmium (NiCd), a climate-controlled room is ideal. If you have no access to air-conditioned storage, keeping batteries in a cool and dry place, such as a shed or cabinet, can also help protect them.
Moisture is another enemy of battery life. Storing batteries in damp or humid environments can lead to corrosion of the metal contacts, which compromises the battery’s ability to charge and discharge properly. Over time, corrosion can permanently damage the battery, resulting in decreased capacity or complete failure.
To protect your power tool batteries:
Keep batteries in a dry space with good air circulation.
Avoid basements or garages where moisture levels fluctuate.
Use a battery storage case or holder to provide additional protection from humidity.
If you live in an area with high humidity, consider using desiccants, like silica gel packs, in your storage area to absorb excess moisture and maintain a dry environment.
Lithium-ion batteries, commonly used in modern power tools, have become the standard due to their high energy density and longer lifespan. However, improper charging practices can shorten their lifespan. Overcharging, or leaving the battery on the charger for extended periods, can generate excess heat and reduce the battery's capacity. Similarly, completely discharging a lithium-ion battery to zero can cause irreversible damage to its cells.
To store your batteries properly:
Charge to around 50% to 70% before storing them. This charge level helps preserve battery health without stressing the cells.
Avoid leaving the battery in the charger for extended periods after it has reached full charge, as it may cause overheating or damage to the internal components.
For NiCd and NiMH batteries, it’s essential to perform a full discharge and recharge cycle every few months to prevent the development of "memory effect." This effect reduces the battery’s capacity and run time if the battery is constantly charged before it’s fully depleted.
If you don’t plan to use your power tool for an extended period, it’s advisable to remove the battery from the tool. Leaving a battery inside a tool for months at a time can cause a slow drain, leading to reduced capacity or, in some cases, complete discharge. This can make it difficult to recharge the battery, reducing its lifespan significantly.
When storing batteries:
Remove them from the tool if they won’t be used for weeks or months.
Store them separately in a cool, dry, and well-ventilated area, preferably in a designated storage box or case to prevent any accidental damage.
This simple practice helps prevent power loss and protects the battery from unnecessary strain.
Batteries should be stored away from metals or any conductive materials that could cause short circuits or sparks. Accidental contact between the battery terminals and conductive objects like coins, nails, or keys can result in a short circuit, leading to overheating, leakage, or fire risks.
To protect your batteries:
Store them in a battery holder or box to avoid contact with other items.
Use a battery sleeve or terminal cover to prevent short circuits when storing loose batteries.
This precaution is especially important for larger batteries, such as those used in industrial or commercial power tools.
Even when not in use, it’s important to check on the condition of your batteries periodically. Regular maintenance helps identify any potential issues before they lead to complete battery failure. Inspect the batteries for any signs of swelling, leakage, or corrosion around the terminals. If any issues are found, it’s crucial to dispose of the battery properly and replace it with a new one.
