My Samsung pl 150 camera is not I used it a lot, but now I can't not turn it on. I have to press the battery inside to turn it on. Yes What is the reason...
The manufacturing process of 3C lithium batteries is divided. in four procedures:
The basis is the production of pole pieces
The core is the assembly of the battery core
The key process is cell activation, which includes battery formation, division capacity and testing
The last step is battery packaging, which is related to the quality of the finished battery.
In the production of 3C lithium batteries, each step directly affects the quality and safety of the battery. The performance tests of 3C lithium batteries include basic performance, safety performance, environmental performance, electrochemical performance and elasticity. The chip microneedle module can transmit current between 1-50A during testing, has strong overcurrent capability and has an average life of 20W, which can effectively improve the testing efficiency of 3C lithium batteries and ensure efficient and safe testing.
How much batterys 150 Ah 2 V are required
Hello, thank you for using a Samsung digital camera!
According to your description, this could be caused by the battery compartment's loose metal gasket or contact failure. It is recommended to send it to a service center.

Are lithium-ion battery factories harmful to the human body? I insert seals in a semi-automatic workshop, is this harmful?
Generally, a lithium battery is 3.75v, 1860 mAh. If it is 12V, at least 4 batteries must be connected in series. At the first level, a battery is 1860 mAh,multiplied by at least one. 100 batteries can meet your needs. 3.7 V 50,000 mA is equivalent to 3.7 V 50 A. So to form 12 V there are three 3.7s in series, and to form 150 A there are three in parallel, so 3 × 3 = 9 are necessary. Because the battery must be configured in parallel to solve for capacity and in series to solve for voltage. Therefore, first determine the number of parallel connections according to the capacity: 100 Ah/3 Ah≈33 parallel connections. Then determine the number of series connections based on voltage. The lithium battery voltage is 3-4.2V, and the voltage after three series connections is 9-12.6V, which meets the voltage requirements of 12V battery.
< p>So the total number of 18650 lithium batteries needed is: 33 in parallel? 3 in series = 99 cells. Before assembling these batteries, it is best to affix an O-shaped insulating gasket (available online) tothe positive electrode. In order to prevent overcharging and overdischarging and ensure balanced charging and discharging, the battery is also equipped with a special device. protection plate for lithium batteries.It is best to use 6 and 3 link nickel strips to connect the batteries, and use a spot welder for welding. If the conditions are not met, zinc chloride can be used as the flux, and a high-power electric soldering iron can be used to complete the tinning of both ends of the battery. After cooling and cleaning, use rosin to help connect the solder and copper wires.
The finished battery should be wrapped in a large heat shrink tube or insulating film and then installed into the case.
To assemble a 12V100AH battery using 18650 batteries, you need to connect them in series first, thenin parallel.
First connect the 18650 batteries in series in a 12V voltage group. , then connect multiple groups in parallel to increase the capacity and reach 12V100AH battery
Three 18650 batteries can get a voltage of 12V
The rated voltage of a single 18650 battery is 3.7 V and the total voltage is 4.2 V
3x3.7V=11.1V; 3x4.2=12.6V
So we think 3 18650 batteries connected in series can get 12V voltage
33 groups of 3000mAh 12V voltage 18650 groups connected in parallel Get 100Ah
33x3000mAh=33x3Ah=99Ah, close to 100Ah
So we think that 33 18650 groups of 12V voltage can be connected in parallel to obtain a capacity of 100Ah
Total used 33x3=99 3000mAh 18650 batteries
Finally, just add a protection plate to the lithium battery
If used as a battery core, the electrolyte will have an impact on the body,so don't do it.
If it is only a battery assembly, it is absolutely harmless to the human body.
However, some batteries require injection molding, and the exhaust gas from injection molding has a certain impact on the body.
If it's not one of the above workstations, you should be fine.
