Finding some carbon graphite electrodes is usually a pretty easy thing to do. You first need to buy or find some zinc carbon batteries. Ypi need to make sure they are zinc carbon and not alkaline or rechargeable types such as Nickel Metal Hydride (NiMh) or Lithium Ion (LiIon or LiPo).

batteries. It also makes large-sized carbon rods for railway signalling equipment. This year it expects to produce 2,400 million carbon rods. However, the Company is expecting a slowdown in the battery market because of poor rains. Rural markets form a big chunk of battery sales, which go into gadgets such
The carbon rod is a conductor only and does not undergo reduction. The voltage produced by a fresh dry cell is (1.5 : text{V}), but decreases during use. An alkaline battery is a variation on the zinc-carbon dry cell. The alkaline battery has no carbon rod and uses a paste of zinc metal and potassium hydroxide, instead of a solid metal anode.
