Generally, wireless mice and keyboards priced below 100 yuan on the market use AA or AA alkaline batteries, while wireless keyboards and mice priced above 100 yuan use batteries rechargeable lithium batteries. Regardless of the form of battery used, their duration of use is similar, approximately 1 month of use. If we compare from the perspective of environmental protection, it is better to use rechargeable batteries.
The current required by the wireless mouse and keyboard is very low, and the voltage of a single ordinary alkaline battery can be as low as about 0.8 V. Therefore, when the ordinary battery of the wireless mouse is exhausted. and the keyboard, the battery Electricity is basically consumed. The cut-off voltage of the rechargeable battery is 1V. If it is lower than 1V, the rechargeable battery will be over-discharged and its service life will be shortened or even shortened.But if the rechargeable battery is used in 0.8V environment for a long time, the life of the rechargeable battery will be reduced because the wireless mouse is often used to charge and discharge the rechargeable battery.
Can the rechargeable lithium iron phosphate battery only last 3 days when installed on the mouse? Isn't it better than regular alkaline batteries? Is the usage wrong?
This is not possible. The tensions of the two are completely inconsistent. The rated voltage of lithium polymer battery is 3.7V and the fully charged voltage is 4.2V, while the rated voltage of lithium iron is 3.7V. Phosphate battery is 3.7V .2V. A fully charged battery is 3.8V. If two are connected in parallel, the lithium iron phosphate battery will be overcharged and the lithium polymer battery will be undercharged.
All d 'first, I don't havenever seen. a wireless mouse that uses two AA batteries. It's a section. So if you use a lithium iron phosphate battery instead, its proper operation depends entirely on the design of the mouse's power circuit. I just bought two 600 mAh lithium iron phosphate batteries a few days ago and never thought about using them with my wireless keyboard and mouse. Because I'm afraid its power circuit won't be able to support such a high voltage (it was originally 1.5V, but suddenly increased to 3.2V). If it cannot support the pregnancy, the keyboard and mouse will fail. a short delay. I tried a flashlight that used a 1.5V battery (I recently bought a new small flashlight with a strong light, and the old non-strong light flashlight was also LED. It was very painful when I tried it) and I tried the lithium iron ph batteryosphate. Confirmed that the brightness is high, but not as bright as the new one. After trying it for a while, I found that the middle of the light spot suddenly became darker. I immediately turned off the flashlight when I noticed it. I try again after a while to get it to happen again. I went back to using the original 5th battery and the above problem is gone. So I confirmed that if I use lithium iron phosphate batteries for my old small flashlight, it will only burn the old flashlight. According to your experience, try the original battery. If the mouse works fine and consumes the same amount of power as before, just treat it as if it is fine and stop trying the 3.2V battery again and replace it with a 1.5V battery . If it uses more power than before, you may have damaged the mouse by changing the battery in such a way.random. Let's learn from each incident.
