4.Are there any specific storage requirements for 3.7V rechargeable batteries?

Yes, there are specific storage requirements for 3.7V rechargeable batteries to maintain their performance and prolong their lifespan:

Partial Charge: Store the batteries at around 50% charge if they will be unused for an extended period. This helps prevent overdischarging or overcharging during storage.
Cool, Dry Location: Store the batteries in a cool, dry place away from direct sunlight and extreme temperatures. High temperatures can accelerate battery degradation.
Avoid Extreme Temperatures: Avoid storing batteries in environments with temperatures below freezing or above 45°C (113°F), as this can degrade battery performance.
Proper Packaging: Store batteries in their original packaging or in dedicated battery cases to prevent short circuits and physical damage.
Regular Inspection: Periodically check stored batteries for signs of damage, such as swelling, leakage, or corrosion on the terminals. Dispose of any damaged batteries properly.

5.What should I do if my 3.7V rechargeable battery starts to swell or leak?

If your 3.7V rechargeable battery starts to swell or leak, it’s important to handle it carefully to minimize the risk of injury or damage. Here’s what you should do:

Stop Using the Battery: Immediately remove the battery from the device or charger it’s connected to and stop using it.
Handle with Care: Wear protective gloves and eyewear when handling the swollen or leaking battery to avoid contact with any leaked electrolyte.
Isolate the Battery: Place the battery in a non-flammable container or bag and store it in a cool, dry place away from flammable materials or heat sources.
Dispose of Properly: Dispose of the swollen or leaking battery according to local regulations for hazardous waste. Many municipalities have specific guidelines for the disposal of damaged or leaking batteries.
Clean Up: If electrolyte has leaked onto surfaces, clean them with a mild detergent and water, taking care to avoid skin contact.
Contact Authorities: If the leaking battery poses a significant safety hazard, such as emitting smoke or a foul odor, contact emergency services for assistance.

Never attempt to puncture, disassemble, or dispose of a swollen or leaking battery in regular household waste. Follow proper safety procedures and dispose of it responsibly to prevent environmental contamination and injury.
