Any soldering requires accuracy and certain skills, and soldering batteries - even more so. The battery is likely to overheat and may be discarded. But still, you can do this procedure yourself if you have a soldering iron, some tools and straight hands. The eyes are afraid, the hands do, as they say, so feel free to fight!
Necessary
- - soldering iron;
- - solder;
- - flux;
- - rosin;
- - hydrogen apparatus.
Instructions
Step 1
Gently clean the surface of the battery. To prevent rapid oxidation, apply fluxes to the wiped areas. They will increase the fluidity of the molten solder and the solder will be stronger. When working with batteries, it is best not to use refractory solders, as they require a higher temperature that the battery may not be able to withstand.
Step 2
Choose a low melting solder - it's not as strong as a high melting solder, but will work for batteries. There are also very low-melting alloys with even lower melting points (about 100 degrees), but unfortunately they are even less durable. They are applicable for soldering transistors and crystals.
Step 3
When soldering, use a variety of fluxes to protect the metal surface and improve solder wetting to the metal surface of the battery. These actions are necessary because during soldering, the temperature rises greatly, and the oxidation rate increases, due to which the solder wets the parts worse. For soldering batteries, fluxes are suitable, which protect the heated metal surface from oxidation. In this case, rosin is perfect.
Step 4
Wipe the seam with a napkin, having previously moistened it in acetone, regardless of the type of flux used. Also clean the seam with a brush soaked in solvent to remove any remaining dirt and flux.
Step 5
If you don't find anything other than lead, be careful because it is very fusible. Even the smallest residence time of lead in the burner will cause melting. Therefore, while brazing, place the torch parallel to the brazing point and do not point directly at it.
Step 6
Do not use tin solders if the batteries are made of lead. Tin is soluble in electrolyte, so only use lead. Watch out for the flames of the hydrogen apparatus so that it does not excessively melt the lead and ruin the battery. The flame length of the nipple should be within 15 millimeters.
