How to activate the battery if it has not been used for a long time
With the popularity of electronic devices, batteries are used more and more frequently. But sometimes, we encounter situations where the battery has not been used for a long time and cannot be charged or discharged normally. This article will give you a detailed introduction to how to activate a battery that has not been used for a long time, and provide structured data to help you better understand.
1. Why does the battery fail if it is not used for too long?
If the battery is not used for a long time, the activity of the internal chemical substances will decrease, and even "passivation" will occur. Here are common battery types and their causes of failure:
| Battery type | Failure reason |
|---|---|
| Lithium-ion battery | Excessive discharge causes the protection circuit to lock |
| NiMH battery | Voltage is too low due to self-discharge |
| Lead acid battery | Vulcanization phenomenon |
2. How to activate different types of batteries?
The activation methods are different for different battery types. The following are the specific steps:
| Battery type | Activation method | Things to note |
|---|---|---|
| Lithium-ion battery | 1. Use the original charger to charge for more than 12 hours 2. Try using an activator or professional equipment | Avoid using non-original chargers |
| NiMH battery | 1. Slow charging for 24 hours 2. Activation using charge and discharge cycles | The first charge requires complete discharge |
| Lead acid battery | 1. Add distilled water 2. Use a desulfide charger | Pay attention to safety protection |
3. Common misunderstandings about battery activation
When activating the battery, many people fall into the following misunderstandings:
| Misunderstanding | Correct approach |
|---|---|
| Grill the battery over fire | Absolutely prohibited, may cause explosion |
| overcharge | Charge according to the time specified in the instruction manual |
| Freezing battery | Ineffective for lithium batteries and may damage the battery |
4. Battery maintenance tips
In order to prevent the battery from failing due to long-term use, you should pay attention to the following maintenance methods:
| Maintenance method | Applicable battery type | Frequency |
|---|---|---|
| Charge and discharge regularly | all types | once a month |
| maintain the right temperature | all types | long term |
| Semi-electric storage | Lithium-ion battery | When not used for a long time |
5. Professional advice
If the battery cannot be activated after several attempts, it is recommended to:
1. Consult professional maintenance personnel
2. Consider replacing the battery with a new one
3. Choose brands with guaranteed quality when purchasing
6. Safety warning
When handling expired batteries, be sure to pay attention to the following safety precautions:
1. Avoid battery short circuit
2. Do not disassemble the battery
3. Keep away from flammable items
4. If the battery is found to be swollen, stop using it immediately
Through the above methods, most batteries that have not been used for a long time can be successfully activated. However, it should be reminded that if the battery has been seriously aged, the activation effect may be limited. It is recommended to replace the battery directly with a new one to ensure safe use.
