Built to house two standard D-size batteries in a rugged enclosure, it offers seamless plug-and-play connection for laboratory circuit setups.\n\nMolded from high-impact, non-conductive ABS plastic, this enclosed battery box securely holds two D-cell batteries to supply steady DC voltage (3V) for experimental setups. It features a top-mounted polarized plug terminal designed to connect easily to standard lab power leads, banana plugs, or connector cables. The sturdy rectangular shell protects batteries from physical damage, accidental short circuits, and chemical leaks during active classroom handling.\n\nFully covers and secures two D-size batteries, protecting users and work surfaces from accidental short-circuiting or battery acid exposure. The integrated top socket header enables rapid, reliable connection to physics circuit components and experimental leads. Durable, non-conductive plastic body designed to withstand heavy daily use in school and university science laboratories.\n\nInternal spring-loaded metal contacts ensure stable electrical conductivity and consistent voltage output. Ideal for teaching series\/parallel circuits, Ohm's law, electromagnetism, and elementary electronics.\n\nHolds 2 x D-Cell (1.5V) batteries with total voltage output of 3V DC in standard series setup. Compatible with alkaline, heavy-duty, or rechargeable D-size cells. The top socket connector accepts matching laboratory plug cables or pin connectors for easy integration into circuit boards. Batteries sold separately.","brand":"edumartstore","offers":[{"title":"Default Title","offer_id":47214057357500,"sku":"3","price":99.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/8566\/2908\/files\/WhatsAppImage2026-07-30at4.48.32PM.jpg?v=1785410410","url":"https:\/\/www.edumartplus.com\/products\/2-d-cell-plastic-battery-case-holder-with-top-terminal-plug-educational-physics-laboratory-circuit-power-supply-box","provider":"edumartstore","version":"1.0","type":"link"}
