Your mobile phone's battery is "starved" and cannot be charged. At this point it should be activated. The first "death by starvation" refers to the phenomenon that the battery cannot be recharged when it has no power or is very low. There are currently two activation methods. The first is to use universal charging, which can be activated in about 20 minutes. The other is to use a more professional, slightly higher voltage power supply, such as a 12 volt power supply at a cell phone repair shop, to start it. Specifically, place the positive and negative poles of the power supply on the positive and negative poles. from the battery for tens of seconds or even minutes, then turn it on after power on. In the end, it can be recharged directly as before after activation. We don't know if this will have asignificant impact on lifespan.
If the above method is not feasible to charge using a meter and the battery is not defective, you must use a “regulated power supply” to start. Black color is connected to the negative pole of. The battery and red color are connected to the positive pole of the battery. The charging voltage is 3.8V and it is ready to use, no need to charge for 12 hours after first use. The series connection method connects a normal voltage 12 volt battery in series to the battery assembly. For example, if the original car has a 48V-20AH battery, we will connect the 12V-20AH batteries in series. A 12V battery has a voltage of about 13V, which is enough to increase the voltage of the entire battery after a 12V battery is connected in series and then charged with the original charger, so that the electricity can be charged, bplug in the charger, and the charger is red light, then you can charge the battery. Wait until the charger turns green, then insert the other battery and remove it. This way you can charge normally.
This is actually the result of two 3.6 (3.7) V batteries connected in series. The actual voltage is 7.2V.
Generally divided into: No. 1, 2, 3, 5 and No. 7, among which No. 5 and No. 7 are particularly commonly used. The so-called AA battery is number. 5, and the AAA battery is battery No. 7. Both AA and AAA indicate the battery model. The specific models are as follows:
1. D type battery (large battery/LR20/AM1) diameter ф34.2 height 61.5mm;
2. Type C battery (AA/LR14/AM2 battery) diameter ф26.2; height 50.0 mm.
3. AA battery (AA/LR6/AM3 battery) diameter ф14.5 height 50.5 mm.
4. AAA battery (AA/LR03/AM4 battery) diameter ф10.5; height 44.5mm.
5. AA/2 battery (AA LR1/AM5 battery) diameter ф11,0; height 30.0 mm.
6. AAAA battery (AA/LR61/AM6 battery) diameter ф8.0; height 39.5mm.
7. Battery type AAAA/2 (small battery AA/LR61/AM6) diameter ф8.0 height 28.0 mm.

Battery classification:
1. Dry battery
Dry battery is also called. Manganese zinc battery, the so-called dry battery is relative to the voltaic battery, and the so-called manganese zinc refers to its raw material. For dry cell batteries made from other materials such as silver oxide batteries and nickel cadmium batteries. The manganese-zinc battery voltage is 15V. Dry batteries consume chemical raw materials to generate electrical energy. Its voltage is not high and the direct current it can produce cannot exceed 1 ampere.
2. Lead acid battery
The battery is one of the most used batteriesés. Use a glass or plastic tank, fill it with sulfuric acid, and insert two lead plates, one is connected to the positive electrode of the charger and the other is connected to the negative electrode of the charger. , a battery is formed. There are 2 volts between its positive and negative terminals. The advantage of batteries is that they can be used repeatedly.
In addition, as its internal resistance is extremely low, it can provide significant current. Use it to power the car engine, and the instantaneous current can reach more than 20 amps. The battery stores electrical energy when charging and converts chemical energy into electrical energy when discharging. ?
3. Lithium battery
Battery with lithium as negative electrode. This is a new type of high-energy battery developed after the 1960s. According to the different electrolytes used, they are divided into: batterieshigh temperature molten salt lithium batteries, organic electrolyte lithium batteries, inorganic non-aqueous electrolyte lithium batteries, solid electrolyte lithium batteries and lithium water batteries.
