Universal Battery Charger DIY 4V-18V Homemade

Introduction

A Universal Battery Charger DIY is a handy device that can charge multiple types of batteries without requiring separate chargers for each. It’s an economical and convenient tool, particularly for those who use various devices like phones, cameras, and toys with different kinds of batteries. The majority of universal battery chargers can power both rechargeable nickel-cadmium (Ni-Cd) and nickel-metal-hydride (NiMH) batteries. These chargers usually come with interchangeable adapters suitable for numerous charging specifications. Consequently, users do not require buying a new charger every time they acquire a gadget with diverse power needs since the universal battery charger comes in handy. Additionally, some variations include unique features such as automatic cut-off or reverse polarity protection to avoid overcharging or short-circuiting the cells. A universal charger saves one from having a drawer full of various charging plugs while also handling the stress of remembering which cable corresponds to which device. Following is the battery charger circuit diagram of homemade 12v battery charger or a battery charger wiring diagram which will fulfill your requirement for charging a battery.
