Replacing the old battery on rechargeable bike lights

Recently, the author purchased ten-year-old rechargeable bike lights and discovered that they only functioned for a few minutes after recharging. The author decided to attempt repairing the bike lights at a local queer makerspace, where they used a soldering iron to replace the battery. The process involved cutting open the silicone casing, removing the circuit board, and desoldering the battery.

The author found the battery specifications as "LIR2477" online and ordered replacement parts from DigiKey, including a $3 battery and $8 glue. The repair process took around 2 weeks, and the author waited 24 hours for the glue to cure before using the lights. The project cost about $20 CAD, and the author is hoping the repair holds up.
