After using the Tmall Box, many users reported that the battery of the remote control was not disabled. The newly replaced battery was not powered for one week. According to the users' feedback, Xiao Bian also tested it. So what causes the cat remote control to be so expensive?
Let's take a look at the cause of the problem and the solution.
Poor remote control circuit contact
Because the remote control of Tmall's box is in poor contact, the current is blocked and the heat energy generated is large, causing a waste of battery power. In a very short time, you feel that the battery is dead because even if you are not using electricity, Consumption.
Solution: Place a small piece of confetti on the contact point.
Lynx box remote controller circuit design problems
Use a multimeter to measure the resistance between the positive and negative battery compartment is 2.85K, 2032 battery voltage is generally available between 2.7-3.3V, take the nominal value of 3V, 2032 battery general capacity of 210mAH, such a battery standby The time is 210/(3/2.85)/24=8.3 days.
That is, even if not used, the battery is consumed in one week. The reason for wanting to consume electricity is that the circuit design is unreasonable.
Since the design of the remote control circuit of the Tmall Box is unreasonable, the problem of fast power consumption of the remote control of the Tmall Box is not a case, and the fact is true, otherwise there would not be so many people searching on Baidu.
After checking the circuit, it is finally confirmed that there is a problem with the capacitor C15, as shown in the following figure:
Such a small-capacity DC resistor should be a megohm-class one, and this apparently broken data. The degree of failure of this capacitor is different. The DC resistance is different and the leakage current is not the same. This also explains why some days have leaked, and some have leaked in one or two months.
Solution: Remove the C15 capacitor. Use a nail clipper to clip the C15 off. Don't worry about missing the C15 Lynx box remote control, it will not work. It has other filter capacitors, and there is no problem with the C15.
