This article examines the complex interconnected chains of large- and small-scale trade that sustain the supply of second-hand car batteries as a widespread traditional solution to energy poverty. It traces the routes of goods that support the circulation of batteries from international routes upstream and downstream to urban and rural areas in Madagascar. It addresses the notion of a mundane infrastructure based on economic circuits that support the regular supply of rebuilt batteries as their repair, maintenance and recharge in the course of their second life. The analysis focuses on central nodes along this supply chain where intermediaries organize transactions over heterogeneous regimes of value and discontinuous economic spaces. It highlights the way these entrepreneurs provide solutions for disjunctions via translation and requalification processes. While the trade of second-hand car batteries is more and more subject to control to prevent lead trafficking rings, these secondary circuits of makeshift energy products raise the interweaving moral and material tensions between the contemporary global environmental politics and the survival of the mundane infrastructure of energy poverty.

本文研究了大型和小型贸易的复杂相互联系的链，这些链维持了二手车电池的供应，这是解决能源贫困的一种传统方法。它追踪了支持电池从国际上下游到马达加斯加城市和农村地区流通的货物路线。它解决了基于经济回路的平凡基础设施的概念，这些基础设施支持定期提供重建电池的二次维修期间的维修，保养和充电。该分析着重于该供应链上的中心节点，在这些中心节点上，中介机构通过不同的价值体系和不连续的经济空间来组织交易。它着重说明了这些企业家通过翻译和重新资格认定流程为分离提供解决方案的方式。虽然二手车电池的贸易越来越受到控制，以防止铅走私，但这些临时能源产品的次级电路却在当代全球环境政治与世俗的基础设施的生存之间引发了相互交织的道德和物质张力。能源贫困。
