修复激活一个无电压电池只能这样做，但是不能用经常这样，否则电芯会很快降低容量，严重的会报废，非常感谢留言，期待以后互相交流学习，

你自己可以按照我激活的这种方式可以试试看，希望视频能够帮助到你。

你幫到什麼呢接線你有你接唔講解有多少人會明白

不用客气

谢谢老师的回复

我用筆電的變壓器去充，我電池是20v，筆電是24v的，成功了

这个只能说明电池本来内部电芯就有不行的才会造成损坏。

我使用的充電電池是5Ah 被充的是 是18Ah所以一次沒辦法把被充的電池電壓提升到原廠充電器可以充電的電壓，所以我反覆充了幾次這會不會是造成電池損害的原因。

很多人是没用可调电源的哦。

正常隔3个月充电一下最好。

@@pangchan8273 there is no reason why you would need to cycle lithium ion cells. If it is maintaining a charge then it is not creating any kind of "memory" effect like the old Nicad cells. Ideally you would want to store lithium ion at 50% if it is not going to be used in the next couple of weeks. Doing this lowers the amount of degradation that happens over time. Will you notice a huge difference if you leave your pack charged at 80% or 90%? Not really. Someone that is OCD about extending the life of their cells as much as possible might notice that their pack degraded 20% faster than a pack left at 50% state of charge (roughly 3.7V) but the average consumer will not notice. I think it is a good safety habit to get into since a cell at a lowe state of charge is not only less likely to have a......big moment...but if it does have a big moment having less charge in the battery will slightly reduce the amount of fire and explosive force. Granted, most of the explosions that happen occur during or right after charging so again, not a huge deal but I keep my cells are 3.5V to 3.6V knowing that they self discharge very very slowly and only once a year do I have to go through my stash and see if any have lost enough voltage to warrant a little bit of time on the charger.

就是一个可调电压的平衡充电器

担保你永远得不到回覆！这些自媒体都是不学无术的只是炒作！

好的，以后改进。谢谢提示。
