一位自行车爱好者日前完成了一项DIY维修项目，成功为十年前购买的充电自行车灯更换电池。1该自行车灯在购买多年后出现故障，充电后仅能工作5分钟。1
在当地创意空间的协助下，这位爱好者学会了整个维修流程。1具体步骤包括打开灯具外壳、使用脱焊泵和烙铁移除原有的焊接电池、识别电池型号为LIR2477，以及焊接新电池。1新电池的采购成本为6美元，硅胶胶水成本为8美元，整个项目总支出约为20加元。1完成更换后，自行车灯已恢复正常功能，目前已投入夜间骑行使用。1
A bike light purchased ten years ago recently underwent a successful battery replacement after years of declining performance.1 The light had deteriorated to the point where it would only function for approximately five minutes after charging.1
To revive the fixture, the owner undertook a hands-on repair project at a local creative makerspace.1 Using desoldering pumps and soldering irons, the owner learned to open the light's casing, remove the old soldered battery, and identify the battery model as LIR2477.1 A new battery was procured for six dollars, with silicone adhesive costing an additional eight dollars, bringing the total repair cost to approximately twenty Canadian dollars.1 Following the installation of the new battery, both bike lights returned to working condition and are now in regular use for nighttime cycling.1
