RE: SLC-Home Repair Club S23W1||Today I repaired the rechargeable mini LED handlight.
You have done a great job @mahadisalim Brother, repairing the cheap mini LED light available in the market, However, it could have been better if some important tests were done. For example, it was necessary to check the battery voltage and the battery charging output with the charging connection using a multimeter, so that it can be confirmed whether the battery is charging properly.
Also, it is important to keep some things in mind to make the 3.7 volt battery connection last longer. Sometimes the solder can run if it is not soldered professionally. Before connecting to the battery terminal, the area must be cleaned and rubbed with a little bit of a rag, so that the solder holds well. If the temperature of the soldering iron is not sufficient, the soldering may be weak and the connection may run later. If you follow these points, the repair will be more effective in the future. Good luck.

Thank you very much for the advice. I know from my colleague that the backup is good so no need to change the battery. After opening the set up I cleaned the battery point connection point with the circuit.
Thanks for your explanation. An important point for new learners is that while repairing any battery-powered item at home, one should first check the voltage and charging output with a multimeter. Doing this will make it easier to understand the actual condition of the battery and avoid unnecessary changes. New learners will be able to clear up the matter.
