How to Store Batteries Properly to Maximise Lifespan

Proper storage can significantly extend the lifespan of your batteries, sometimes even doubling their effective life. Avoid common pitfalls and keep your batteries running efficiently for longer with our practical guide.

Why Proper Battery Storage Matters

Batteries are essential to modern life, powering everything from smartphones and laptops to professional cameras and power tools. But incorrect storage can severely reduce their lifespan. Factors such as extreme temperatures, moisture, and incorrect charge levels can rapidly degrade battery health.

Here’s how to store different types of batteries effectively and avoid common errors that lead to unnecessary costs and replacement.

Optimal Storage Temperature

Temperature plays a crucial role in battery longevity. Excessive heat accelerates battery aging, while cold conditions can significantly reduce their capacity. For most battery types, storing them at temperatures between 15°C and 20°C is ideal. Always keep batteries away from direct sunlight, heating elements, or cold, damp areas.

Batteries for Extreme Conditions

Certain professional uses demand batteries that withstand harsh conditions. For photographers, filmmakers, or reporters working in challenging environments, we recommend Newell SupraCell batteries. Designed specifically for professionals, SupraCell batteries endure extreme temperatures from -20°C to 90°C, feature advanced NTC resistors for stable performance, and are enclosed in fire-resistant casings. These batteries also offer intelligent IC protection to prevent overheating, overcharging, and overloading.

Correct Charge Levels for Storage

Battery type dictates the best charge level for storage:

• Lithium-ion (Li-Ion, Li-Poly): Store at 40-60% charge. Avoid full discharge or maintaining a full charge, as both accelerate battery degradation.
• Nickel-metal hydride (Ni-MH): Ideally stored at 30-50% charge to maintain peak efficiency.
• Lead-acid (SLA, AGM, gel): Fully charged storage prevents irreversible cell damage known as sulfation.

Protect Batteries from Moisture

Moisture is a primary enemy of battery longevity, causing corrosion and damage. Ensure batteries are stored in dry environments with adequate airflow. Avoid airtight plastic containers unless equipped with moisture control solutions like silica gel sachets, particularly in humid climates.

Safe Storage Practices

Safety should always be a priority:

• Use original battery caps or specialised containers to avoid accidental short circuits.
• Never store batteries loosely together; contact points can inadvertently touch, leading to shorts.
• Avoid metal storage containers unless insulated, as they pose a significant risk of short-circuiting.

Common Battery Storage Mistakes to Avoid

• Allowing lithium-ion batteries to be fully discharged, causing irreversible cell damage.
• Storing batteries in very hot or very cold environments, reducing lifespan and capacity.
• Leaving batteries in devices for extended periods, increasing the risk of leakage or swelling.
• Failing to periodically recharge certain batteries (Ni-MH and lead-acid types), resulting in reduced capacity.

Preparing Batteries for Long-Term Storage

For extended storage periods, additional precautions are beneficial:

• Regularly check battery voltage, particularly for lithium-ion types.
• Prevent accidental short circuits by keeping batteries away from metal objects.
• Label batteries clearly with their last charge date to facilitate regular maintenance.

Device-Specific Battery Storage Tips

• Cameras: Store lithium-ion camera batteries at 40-60% charge, ideally separate from the device, and recharge periodically.
• V-mount Batteries: Common in film production equipment, these should be stored at room temperature and recharged regularly.
• Power Banks: Maintain a 50-70% charge level, recharging periodically to avoid capacity loss.
• Power Tools: Store tool batteries charged between 30-50% in dry locations to prevent cell damage.
• Drones: Drone batteries should be kept partially charged at room temperature, ideally stored in protective LiPo bags.
• Laptops: For extended inactivity, store laptop batteries separately, if possible, charged to around 40-50%.

Environmentally Responsible Disposal

Batteries inevitably reach the end of their lifespan. When this happens:

• Never discard batteries in regular household waste; they contain hazardous materials.
• Recycle through electronic waste collection points or designated recycling facilities.
• Proper recycling protects the environment and helps recover valuable materials.

By implementing these best practices, you can significantly extend your battery’s lifespan, ensuring reliability and cost-effectiveness. For replacements, choose high-quality batteries from Newell—trusted by professionals worldwide for exceptional performance and durability.
