For the majority of outdoor enthusiasts who enjoy activities like drone flying and camping, electronic devices such as smartphones, tablets, digital cameras, and MP3 players are indispensable. However, the frustration of running out of battery power during outdoor adventures is a common concern. How can we extend the lifespan of rechargeable batteries in the wilderness?
Temperature Characteristics:
The migration rate of electrolytes and electrode sheets in rechargeable batteries is closely related to temperature. Fluctuations in temperature significantly affect the technical performance of rechargeable batteries.
- Storage Temperature:
- Avoid long-term storage at temperatures below -20°C, as it can damage the internal chemical components of the battery.
- High temperatures exceeding +65°C can lead to gas generation and accelerate the aging and deterioration of the battery.
- Charging Temperature:
- Charge batteries within the temperature range of 0°C to 45°C.
- Discharging Temperature:
- Discharge batteries within the temperature range of -20°C to 65°C.
- Specialized low-temperature or high-temperature batteries may be used in specific situations.
Storage Recommendations:
- Store batteries in a cool, dry place with a temperature ranging from -20°C to +65°C.
- Extremely low temperatures can cause the electrolyte to solidify, rendering the battery unusable.
- Excessive heat can lead to gas generation and accelerate the aging process.
Charging Considerations:
- Charge batteries in environments with temperatures between 0°C and 45°C.
- For new or long-unused batteries, perform two to three cycles of low-current (0.1C) charging and discharging to activate the active materials.
- Periodically charge unused batteries (every three months) to maintain optimal capacity.
Battery Usage Tips:
- Avoid Burning or Disassembling Batteries:
- Battery chemicals can be corrosive and harmful to the skin and eyes.
- Handle Connectors Carefully:
- Avoid pulling or stressing battery leads and connectors to prevent damage.
- Avoid Mixing Different Battery Models:
- Do not mix batteries of different models.
- Proper Welding for Different Battery Models:
- When welding different battery models, use connecting plates or suitable methods.
- Initial Use Charging:
- Charge batteries with a small current before the initial use.
- Avoid Parallel Charging:
- Do not parallel charge batteries to prevent irregular charging currents.
- Prevent Reverse Polarity:
- Never use batteries in reverse or short-circuit them.
- Full Discharge and Prolonged Charging:
- Extend charging time after a full discharge to achieve full capacity.
- Storage Conditions:
- Store batteries in a cool, well-ventilated, and dry environment with temperatures not exceeding 45°C.
- Avoid Acidic Gases and Open Flames:
- Keep batteries away from acidic gases and open flames.
Understanding the distinction between primary and secondary batteries is crucial. Primary batteries, such as zinc-manganese, alkaline, and lithium button cells, are for one-time use, while secondary batteries, such as lead-acid, nickel-cadmium, nickel-metal hydride, and lithium-ion batteries, can be recharged.
In the outdoors, newcomers often face three challenges: getting lost, running out of water, and running out of battery power. Learning to maintain batteries and extend their lifespan makes outdoor activities more convenient!
