If you are an Oral-B user, you should have noticed that the brush becomes not so powerful if it is fully charged - after the green light is off.
So I use a timer to charge it only before and after the time I use it. For example, I brush around one o'clock at night so I set it to start charging at 10PM and turn it off at 2AM. About 4 hours. Similar for the morning, for another 4 hours.
Then I simply leave it in the charger all the time after each use. This way, the brush is still being charged when I use it and it is always in its full wings.
Depending on how many minutes you brush every time, you may set the total charging time anywhere from 5 to 10 hours. The key is to give it enough time to charge but never be fully charged before you use it. I brush for about 5 minutes each time and 4 hours (8 hours per day) is about perfect.
你应该换电池了，很好换的
ReplyDelete跟电池没关系，我换过，没效果，新买的牙刷也需要这样做才能有力。
Delete你买的电池有问题或者你的焊接有问题，我换之前只能用3天，换过后充电一次就可以用10天，达不到原装14天的状态
Delete我这里说的不是电池的容量问题或充一次电用多久，而是怎么让牙刷十足的有劲。我很早就注意到：如果你让电池充足了，比如晚上8点充电自己停止了，你晚上10点来刷牙，牙刷的劲显得不足。如果你来刷牙的时候，充电还在进行中，那么牙刷的劲非常的大。所以我就想了这个办法，核心是当我来刷牙的时候，牙刷还在充电中。我每次刷完后都放回到充电器上去。
Delete有没有劲没取决于充电电池的电压，如果电池在刚冲完的时候和放了几个小时后电压有明显差别的话，这个电池已经老化了
Delete牙刷里面绝大部分应该是用电压来判读电池的剩余容量的，应该没有电量计数管理芯片。。。。
通常情况是你说的那样。Oral-b的情况特殊，是我注意到的那样。原因我不清楚，只有Oral-b的工程师才知道。我想象的原因是：牙刷里有一个限制的门槛，充足了电之后，电压达到最高，超过了那个门槛，转速和震动的频率会被限制。
