No.
1. The battery used by the electronic scale is a 7.4V battery, which is not compatible with the 3.6V 600mAh lithium battery of the mobile phone.
2. Some electronic scales also use lithium batteries, but the capacity of the 3.6V 600mAh lithium battery of the mobile phone is too small and cannot meet the normal power requirements of the electronic scale.
The battery of the electronic scale is no longer usable. Can the charging cable be connected directly to the wire inside the electronic scale
The battery model uses 3v lithium? battery.
An electronic scale is a weighing instrument that uses Hooke's law or force to measure the mass of an object using the lever balance principle. Electronic scales are mainly composed of three parts: a supporting system (such as a bodyscale, a scale body), a power conversion system (such as a lever transmission system, a sensor) and a value system (such as a scale body, an electronic display). instrument). According to the structural principle, it can be divided into three categories: mechanical scales, electronic scales and electromechanical combined scales.
Yes, but wouldn't it be more convenient to have batteries? Your battery is broken.
The lead acid battery inside your electronic scale is too severely vulcanized (some even use it once and cannot be recharged after purchasing it, some last 2 weeks and others 2-3 weeks). months, the better the quality of the lead-acid battery, the slower the sulfur passivation), resulting in small capacity, short battery life, days, hours, minutes or even seconds , and always a beep or 0 ssecond (0 seconds. , the battery at this time is equal to an open circuit state, as if it does not exist).
Sulfide passivation principle: Lead-acid batteries form lead sulfide after discharge. Once lead sulfate is gradually and slowly sulfated (crystallization and salinization), it does not participate in the charge reaction, resulting in reduced sulfide passivation. total battery capacity.
For example, a 4 Ah lead-acid battery is completely idle, the remaining power is 25% (1 Ah), and the energy shortage is 100% - 25% = 75% (3 Ah). the power-deficient part gradually generates sulfuric acid. Over time, the power deficient part is 2.9 Ah... after a while... 2.5 Ah... after a while. .2.0AH...after a while...1AH...finally 0AH, at this time the total battery capacity is 1AH. Including self-discharge, capacityactual total will be less than 1AH.
This is why lead-acid batteries must be stored fully charged.
The following is a professional analysis:
First, determine whether it is a lead acid battery problem or a circuit problem. charge.
1. Determine the problem with the charging circuit. If the electronic scale can be turned on when plugged in, it means the charging circuit is good, but the lead-acid battery is broken (battery open circuit) or the charging circuit is defective. the internal circuit is broken;
2. If the electronic scale can be turned on if plugged in, the charging part is good, but unplug the charging cable and wait for a short time (it may be 0 seconds, a few seconds, a few minutes or a few days). It was running out of power and the electronic scale issued a low power alarm, indicating that the battery wasThe lead-acid battery was not powered and could no longer function. be loaded. The lead-acid battery needed to be replaced or repaired with a 4V lead-acid battery repair tool.
Also, rotten lead-acid battery plates cannot be repaired by vulcanization.
3 solutions:
1. Purchase a 4V repair instrument for lead-acid batteries and vulcanize the battery separately. Before repairing, open the battery cover and add 1ml of deionization to each. water hole, let it sit for 1 hour and use lead acid battery pulse repair instrument to repair it. Disadvantages: the repair may have no effect, the success rate is less than 20%, and the repaired battery will need to be repaired from time to time (up to 2 months, as little as a few days) when it loses power. power. ;
2. Add “lead-acid battery repair fluid” to the lead-acid battery.The repair success rate is less than 10%, and the repair should be assisted by a repair instrument at the beginning. to be efficient. Without repair instrument, there is almost no effect. It is difficult to repair it once with a repair tool.
3. Shield Power electronic scale lithium battery from a certain store, which can simulate lead-acid lithium batteries with a discharge efficiency of 99% (different from ordinary electronic scales). The discharge efficiency of lithium batteries is only 30%), it has super long battery life and standby, and is fully suitable for 4V electronic scale system. It can be plugged in 24 hours a day and does not damage the battery at all. It is truly worry-free and can be used for more than 5 years. . Fix the problem completely.
