Recently, the author discovered their ten-year-old rechargeable bike lights weren't holding a charge. Seeking a budget-friendly solution, they decided to replace the battery. At a local queer makerspace, the author used a soldering iron to disassemble the lights and replace the battery with a new LIR2477 model. After reassembling the lights and waiting for the glue to cure, the bike lights were ready to use.
The repair cost roughly $20 CAD, which included the new battery and adhesive. The lights have been in use since then, with no need for recharging.
