Replacing the battery in my electric toothbrush
2 days ago
- Revived soldering skills to replace the aging battery in a Braun/Oral-B electric toothbrush, upgrading from 700 mAh to 2300 mAh.
- Decided to invest in a Pinecil v2 soldering iron and accessories (total about 55€) instead of buying a new toothbrush for 18€.
- Successfully desoldered the old battery, installed a new NiMH battery with solder tabs, and reassembled the toothbrush.
- Plans to upgrade other household toothbrushes and criticizes the lack of repairable designs, advocating against e-waste.
