Replacing the old battery on rechargeable bike lights
3 hours ago
- The author attempted to repair old rechargeable bike lights that only lasted 5 minutes after charging by replacing the battery.
- They cut open the silicone casing, removed screws, and extracted the circuit board.
- Desoldered the old battery using a desoldering pump and guidance from iFixit and friends.
- Identified the battery as LIR2477 with help from an LLM, then ordered two replacements and silicone glue from AliExpress for about $20 CAD.
- Soldered the new batteries, reassembled with fewer screws, and glued the casing back together.
- The lights now work, though the author is still waiting for a Mini USB cable to test full battery life.
