In this episode I am going to rebuild the battery of the refurbished Nokia 1610. As you can see, without charger the phone won’t turn on. Even if I plug in the charger, it won’t work for long time. Obvious, it is needed to rebuild the battery. It is old enough. These two batteries will be used as a replacement. Now I try to open the outer housing. Unfortunately, I need to use a lot of force. The cells are held in place with double sided tape, and some glue. I need to be careful, not to crack it. As you can see, the battery is in very bad condition. During the making of this video the phone is 23 years old. It was first released in 1996. I clean the outer housing. I take out the cells from the housing. I take out the connector carefully. After that, I remove all the glue from the inner housing. Now I have to get off the connector from the cells. I cut off the excess. With this foam, I clean the housing thoroughly. I check the polarity with a multimeter. The right side is the positive. Same on the connector. I prepare the new batteries. Solder paste on both side. Two wires on one battery and one wire on the positive connector on the other battery. Now I connect them in series. I quickly clean the housing. After that I dry them. Testing the batteries. Then I link the connector with the batteries. Positive to positive, negative to negative. I fix the batteries with double sided tape. Finally, I place the connector in place. Now I place the wires. Click the locker in place. Finally, I put the rebuilt battery together. Only thing left is the test. If I did everything right, the phone is about to turn on. IT WORKS! Even the charger is working.
