How To Repair Laptop Batteries. By Jestine Yong on February 1, 2017 Share. The Fuse is burned by a controlled FET that heats a resistor inside the Fuse that will immediately open the Fuse. And the Battery Pack Plus is removed from the circuit in the process.
It would become ideal if I could have eliminated to Stereo Shack to buy a pack of 360 ohm resistors, but they are not obtainable. I rummaged through my junk container and found a 270 ohm resistor and a 100 ohm resistor. Soldering these two end-to-end (collection) provided me one opposition of about 370 ohms. (Resistors are usually not really specifically their mentioned value, but differ just a little. Check out the actual level of resistance with the Ohms functionality on your multimeter. My chain of resistors can be really 367 ohms. Furthermore, resistors use a color coding system to indicate their value. The colours shown on the résistors in the example are accurate for the beliefs pointed out.)
Notice the 2nd image. I soldered a little alligator clip to one finish of the resistors. I ended up a soda hay over them and included some sizzling glue at each end to supply some actual physical strength. I scraped the resistor lead opposite the alligator cut to remove any scorching glue that might act as insuIation.
I couId have brought the 367 ohms down to exactly 360 ohms by soldering another resistor of 19000 ohms in parallel to the two resistors. Resistances in parallel function in a different way than resistances in series. (Incorporating 19,000 ohms, if such a resistor were to become available, is certainly even more of a theoretical instance than a serious suggestion.) Right here is usually an online finance calculator for parallel résistances.
To use, just connect the alligator cut to one of the test leads. Established the multimeter tó the 200 milliamp range. Use the uncovered resistor prospect as the probe. Touch the probes tó the battery undér test.
