It can be used. Please charge it first. The capacity will only be reduced by about 10% in 3 months if you use it until it runs out of power, then leave it for another three months. months, the capacity will be very difficult to recover, if stored with electricity, there is practically no loss of capacity, only about 1% irreversible loss, which is very small. If it has been stored for 3 months, the capacity will decrease a bit, but it should still be usable.
If an electric vehicle battery is not used for a long time, its performance will degrade and the energy it contains will slowly be lost. ?
If you charge the battery every month, there will be no problem with the battery; If it is not charged for a year, the battery will have a power phenomenon even if you charge it. now the battery will not have enough power. She doesn'tis not too full and does not last long.
Performance
1. Lead-acid batteries (lead-acid gel batteries) are cheap and have stable performance. Most electric vehicles on the market use this type of battery.
2. Lithium-ion batteries (often called lithium batteries) are more expensive, but they have high specific energy, high specific power, low self-discharge, no memory effect, good cycle characteristics and a wide operating temperature range , no environmental pollution and other advantages.
3. Crystal gel batteries have high cost and stable performance. There are very few electric vehicles using this type of battery on the market. Only a few companies equip them with this high-performance battery. highest safety factor. The advantage of a much longer lifespan than the first two typesof batteries and the advantage of self-healing function also constitute the leading position in the industry. The advantage is that lead acid batteries do not have them, and the disadvantages. Delamination of lead-acid batteries can be avoided.
If cell phones and computers are not used for a long time, the batteries in them will be exhausted and they may not be able to charge .
The method is as follows:
If the lithium battery is not used for a long time, it should be charged every few months. It's lost. The battery is no longer usable, all that remains is to reactivate it. There is a way you can try. Wrap the battery in a plastic bag and place it in the cold room of the refrigerator for a few days (3-4 days). After use, take it out and keep it in a normal environment fort 3-4 days, then charge and). unload it more than 3 times, and it's almost done.
There is another method you can try, which is to keep the battery in your cell phone or computer, use the charger to unplug and plug it in repeatedly, plug in the charger for about 10 seconds, to remove it. and plug it back in for ten seconds. Finally, remove it. Repeat this dozens of times and it will be ready to use again.
