Abstract: Nowadays, the majority of the world relies on dry cells for electronics such as gadgets, appliances, tools, etc. The commercially used dry cells are usually disposable once there is no power left. Although there are initiatives to overcome this statement, it still produces an inventive problem. For example, the charger of a dry cell usually takes up hours to charge a few dry cells and take up spaces that can be used for other stuff. But we can take an example from the useful smartphone which uses a USB port as the main source of charging. By applying that concept, we can now conveniently charge batteries with the help of a normal USB port typically used to save space and time efficiently. So, we are producing an alternative to alkaline batteries with the addition of energy-saving concepts and waste-reducing elements. The USB Rechargeable Battery is simply innovated by taking a normal alkaline battery. Take out the USB port from its body. Measure the USB port with a used small bottle for making the lid. Solder the USB port to the battery. Glue the USB port using a hot glue gun to strengthen the structure. Take another used battery and take out the top end of the battery. Put the top end of the battery into the lid until it fully fits. Apply the lid with the body. Tape using duct tape to tidy up the battery. Based on the research that our team has done, we can conclude that our project, The USB Rechargeable Battery is more efficient and proven to be environmentally friendly. This is due to the fact that “The USB Rechargeable Battery” is the only type of dry cell that does not need to be removed as it can be recharged. It can be used repeatedly without harming the surroundings. This means it is an eco-friendly dry cell.
