How to distinguish the true and false battery of Motorola walkie-talkie

1. Battery inside walkie-talkie Motorola original: only use high-quality batteries that have been strictly tested for many times and meet various standards. The capacity consistency of single battery cells is strong, and the assembled interphone battery has excellent continuous performance and long service life. Counterfeit batteries: The consistency of most counterfeit batteries is poor, which leads to high battery impedance and unreliable battery capacity after assembly mismatch. 2. Flexible circuit Motorola original: use the latest patented flexible cord connection technology to connect internal batteries and electronic equipment. Soft copper film flexible circuit makes the production process automatic, the components are miniaturized and the reliability is high. Ensure reliable quality and low impedance, greatly reducing the probability of defective products. Fake battery: A typical fake battery uses a wire and a metal plate with poor flexibility for circuit connection. The whole production process adopts manual operation or manual welding. Therefore, the probability of short circuit and welding is greatly increased. Because of insufficient welding technology, the battery impedance may be high. 3. Motorola's original key electronic devices: ensuring the safety and excellent performance of walkie-talkies, batteries and chargers is the most basic principle. Multi-way switch-safety element, which can reset the current when the temperature is high. Thermistor-a kind of temperature detection element, which can effectively monitor the battery temperature, accurately control the working state of the circuit and prevent overload. Diode-prevents current from flowing from the battery to the charger. Counterfeit batteries: Usually inferior electronic components are used, and the welding quality of components is also poor. Some components may even fail and will not work properly at all. 4. Motorola original mechanical parts: shock absorbers and fillers are used to protect the battery and keep the arrangement position of devices in the battery. When used in the harsh conditions of sudden impact, the damage of parts can be greatly reduced. In order to ensure that the two-way walkie-talkie can work stably and normally in extremely harsh environment, Motorola original battery adopts ultrasonic technology to weld the high-quality plastic battery shell with other flexible materials inside. Counterfeit batteries: There is usually no protective material to protect the position of internal batteries and fixed components. Fake batteries are often roughly assembled, and internal components are often loose, which has hidden dangers. Fake battery cases are often glued together by hand, so the connectivity is poor. This kind of battery can't stand the sudden impact of the outside world, or accidentally fall from a height, and the result can be imagined. Using Motorola original battery is an indispensable part in the overall system design of two-way wireless walkie-talkie, so whether it is used correctly will have a favorable or even unfavorable impact on the use of walkie-talkie. In order to ensure the excellent performance and reliable quality of walkie-talkies, Motorola has adopted comprehensive design and testing methods for walkie-talkies, batteries and other accessories to ensure product quality. 1. integrated system design When developing two-way radios and other power accessories, Motorola considers them as a whole system. Through overall coordination and optimization, the integrated system design method enables each individual component in the system to maximize its best performance. At the same time, it also ensures that it is easier to find potential problems and improve them when the walkie-talkie, battery and charger are comprehensively tested as a whole system in the early stage of design. How does the battery reduce the performance of walkie-talkies? Many users take the talk time, service life, volume and weight as important evaluation indicators when choosing batteries. Most users don't realize that the problem of battery impedance (or resistance) will directly affect the performance of two-way walkie-talkies and the coverage of calls if it is not considered in the design and manufacture of the system. This performance degradation phenomenon is often called "walkie-talkie sensitivity degradation", which indicates the clarity of the signals received by the walkie-talkie. When the battery impedance is seriously mismatched and exceeds the design limit, the receiving circuit will not work. At this time, the walkie-talkie can only transmit but can't receive information (just talk and don't listen). 2. Strict environmental simulation test All Motorola products (including walkie-talkies and batteries) must undergo strict tests.
