Plastic bags are not recommended for battery storage
Additionally, plastic bags do not provide a stable and controlled environment for batteries. Extreme temperatures, whether too hot or too cold, can negatively impact a battery's lifespan, capacity, and performance. Plastic bags are not effective at regulating temperature and can contribute to extreme conditions. For example, placing batteries in a freezer, which is not recommended, can cause sub-freezing temperatures to prematurely drain batteries.
Another concern with plastic bags is their inability to protect batteries from moisture. While some sources suggest that sealing a plastic bag can prevent moisture damage, it is challenging to ensure a complete seal. Moisture can cause corrosion and damage to batteries over time. Therefore, it is recommended to store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
Instead of plastic bags, consider using the original packaging or a designated battery storage container. The original packaging helps protect the batteries and reduces the risk of short-circuiting. Dedicated battery storage containers keep batteries organized, separate rechargeable from single-use types, and prevent short circuits by avoiding contact between batteries and metal objects. These containers often include built-in charge testers, making it easy to monitor battery levels and maintain safe storage conditions.
In summary, plastic bags are not recommended for battery storage due to the risk of battery contact, temperature extremes, and moisture damage. To ensure the safety and longevity of your batteries, it is best to utilize their original packaging or invest in a designated battery storage solution.

Plastic containers are safe, but avoid metal ones
Storing batteries in a plastic container is generally considered safe, but there are a few important things to keep in mind. Firstly, it is recommended to keep batteries in their original packaging or a designated container to avoid short-circuiting and potential damage. This is especially important if you are storing loose batteries, as they can easily come into contact with each other and cause a short circuit or accidental discharge. If you are using a plastic container, make sure it is specifically designed for battery storage and keep the batteries organized and separated to prevent contact between them.
Additionally, it is crucial to store batteries in a cool, dry place, away from extreme temperatures and moisture. Extreme heat or cold can reduce battery lifespan, capacity, and performance. Intense heat can cause the fluid in the battery to evaporate, leading to battery failure. On the other hand, cold temperatures can form condensation and erode batteries over time. Therefore, it is best to store batteries in a climate-controlled environment without heat fluctuations.
While plastic containers are generally safe, it is important to avoid metal containers for battery storage. Metal objects can cause a short circuit when they come into contact with battery terminals, potentially damaging the battery and the metal itself. Additionally, metal can overheat the battery cell, leading to further issues.
To ensure the safety and longevity of your batteries, it is recommended to follow proper storage guidelines, including separating new and old batteries, regular inspection for damage, and responsible disposal when necessary. By taking these precautions, you can safely store your batteries in plastic containers while avoiding the risks associated with metal containers.

Keep batteries cool and dry
Keeping batteries cool and dry is essential for maintaining their integrity and extending their shelf life. Here are some tips to ensure proper battery storage:
Ideal Storage Temperature
The ideal temperature range for storing batteries varies depending on their type. Alkaline batteries should be stored at around 60°F, while lithium batteries prefer temperatures between 68°F and 77°F. However, all batteries will generally remain in good condition as long as they are stored within the typical range of room temperature.
It is crucial to avoid exposing batteries to extreme temperatures. Temperatures above 100°F or below freezing can reduce the lifespan, capacity, and performance of batteries. This means that storing batteries in the freezer is not advisable, as sub-freezing temperatures can prematurely drain them and impair their effectiveness.
Keeping Batteries Dry and Safe
Batteries should be stored in a cool, dry location, away from direct sunlight and heat sources. Prolonged exposure to a humid environment can cause corrosion and damage. If your batteries get wet, briefly submerged, and show no visible signs of rust, corrosion, or damage, you can dry them off and return them to storage. However, visibly damaged batteries should be discarded or recycled.
Storage Containers and Organisation
To prevent short circuits and accidental discharge, store batteries separately or use a battery organiser. Avoid keeping them in a dedicated "battery drawer" or plastic bag, as they may come into contact with each other or metal objects, leading to potential hazards. Instead, use a battery storage case or container with separate compartments to prevent terminals from touching.
Additionally, always store batteries upright to avoid accidents and potential leakage. For 9V batteries, consider using plastic protectors or covering the posts with electrical tape for added safety.
Maintaining Battery Charge
To maintain battery charge during long-term storage, consider using a trickle charger for car batteries to keep them topped off without overcharging. Periodically check the charge to ensure the battery is ready for use. For rechargeable batteries, avoid storing them in their chargers, as this can lead to overcharging and reduced performance over time. Instead, store them in their original packaging or a battery case at about a 50% charge.

Avoid extreme temperatures
Extreme temperatures can damage batteries of all types. Intense heat can cause the fluid in a battery to evaporate, leading to battery failure. Heat can also cause batteries to burst or catch fire. The extreme heat of a fire can cause battery components to explode with considerable force, and the resulting fumes can be toxic. This is especially true for lithium-ion batteries, which can experience thermal runaway, a domino effect where multiple batteries stored close together succumb to elevated temperatures, increasing the risk of fire and explosion.
Cold temperatures can also damage batteries. Condensation can form at low temperatures, eroding batteries over time. In extreme cold, batteries may freeze, causing irreversible damage to their internal structure and leading to decreased performance and potential safety hazards.
To avoid these issues, batteries should be stored in a climate-controlled environment without heat fluctuations. The optimal temperature range for storing batteries is between 0°C and 20°C (32°F to 68°F). Storing batteries within this range helps preserve their capacity and performance.
There are several methods to keep batteries warm in cold weather. One option is to use a battery heater or wrap the battery with a heating pad specifically designed for this purpose. These devices supply a consistent and controlled amount of heat to the battery, ensuring it stays within the optimal temperature range. Another option is to store batteries in an insulated space, such as inside a home or heated garage, to protect them from freezing temperatures.
It is also important to avoid exposing batteries to direct sunlight or any heat or ignition sources. Batteries should be stored in a cool, dry, and well-ventilated area to minimise the risk of moisture buildup.

Separate old and new batteries
Mixing old and new batteries is not recommended as it can reduce overall performance and cause battery leakage or rupture. This is because batteries have different voltages, capacities, chemistries, and amperage ratings, and when mixed, can create a dangerous situation. For example, a fresh battery has a smaller series resistance than an old battery, and this difference can cause the old battery to heat up and increase power dissipation, which can be harmful to both batteries.
Additionally, mixing rechargeable and non-rechargeable batteries can cause unpredictable and dangerous reactions due to variations in chemical reactions. Different types of batteries are designed for different purposes, and mixing them will not improve device performance. For example, mixing a lithium battery with an alkaline battery will reduce performance and may damage the device.
It is also not advisable to mix battery brands, as there can be small differences in voltage and capacity. For instance, AA alkaline batteries are rated at 1.5 volts, but this number is an estimate, and manufacturers may round up or down. Mixing batteries of different brands can reduce overall performance and cause battery leakage or rupture.
To avoid these issues, it is recommended to replace all batteries within a device at the same time, ensuring they are all from the same brand and of the same type. This will help maintain optimal performance and prolong the lifespan of the batteries and the device.
