Abstract: Exhausted portable batteries collected from the uncontrolled dumping in Yaoundé (Cameroon) are mostly composed of non-rechargeable batteries of type D, type AA, type AAA with minor contribution of type C, type 123, type 9-volt and rechargeable batteries of type AAA. These batteries wastes belong to the carbon zinc, alkaline manganese, NiMH and Lithium chemical systems with 98.12%, 1.00%, 0.53% and 0.35%, respectively, based on the total of 2287 battery waste units collected. However, no battery shows any label about the sound disposal of these batteries at their end-of-life. Several countries forming 83 trademarks are labeled as countries of origin of these battery wastes with China making 66.33% alone. The sole domestic trademark makes 25.74% of these battery wastes and the remaining 7.93% for other countries. Fifty-two percentage of these battery waste units are labeled as containing 0.01–0.025% of mercury, and 3% marked as mercury-free; 45% have no labeling indicating the added mercury. For cadmium, 3% are marked cadmium-free, and 97% do not show any labeling on the added cadmium. These batteries wastes will mostly end up in fire by the uncontrolled burning process despite the cautionary notes warning against such practices.
