How to Store Rechargeable Batteries: Best Practices and Tips

Rechargeable batteries are a great investment for anyone who uses electronics that require regular battery replacements. They are not only cost-effective in the long run, but also environmentally friendly. However, storing rechargeable batteries correctly can be a bit tricky to ensure they last as long as possible.

Why Proper Storage Matters?

Storing your rechargeable batteries properly is crucial because it helps extend their lifespan and maintain their performance. When kept in an inappropriate environment or position, these batteries can easily lose power capacity and even damage themselves from leaking or overheating.


The ideal environment to store rechargeable batteries should be dry and cool with temperatures ranging between 5°C to 15°C. Exposure to extreme heat or cold may cause irreparable damage leading to reduced efficiency on the battery’s part.


When storing your rechargeable batteries, always keep them upright with terminals facing up. Storing them sideways or upside down might lead them into discharging completely over time.

Battery Type Considerations

Different types of rechargeable cells have varying storage requirements based on chemical composition and structure:

NiMH Batteries (Nickel Metal Hydride)

These types of cells are known for their high energy density compared to other traditional NiCad cell technologies used before being faced out due to environmental concerns.
Store NiMH Batteries at room temperature away from direct sunlight for Best Performance

Lithium-ion Batteries:

Lithium-ion technology has become the standard nowadays – commonly used in smartphones, laptops, cameras, and other digital devices
Store Lithium-Ion Batteries at Room Temperature: These kinds of cells operate best when stored around 20°C/68°F ambient temperature

The Don’ts

Don’t Store Dead Batteries

Always avoid storing completely discharged batteries for extended periods. Make sure to charge them fully before storage.

Avoid Water and Moisture Exposure

Water or moisture can lead rechargeable cells into short circuiting, thus reducing their lifespan. Keep your batteries away from water sources or damp surroundings.


Storing rechargeable batteries properly is essential for maintaining their performance and increasing their lifespan while ensuring they remain in good condition until the next use. By following the simple tips outlined here, you’ll be able to keep your rechargeable cells performing optimally for longer durations at a time. Remember always to store rechargeable cells in cool dry environments with terminals facing up and preferably somewhere out of reach by small children as an added safety measure against accidents caused by curious little hands!
