12V Battery Overcharge Protection



If you’re looking for a way to protect your 12V battery from overcharging, creating a DIY homemade solution is possible but requires some careful planning. The key factor in preventing overcharge is to properly size a voltage regulator that will cut off charging when the battery reaches full capacity. This can be achieved by selecting a voltage regulator with the right specifications and connecting it properly to the battery’s charging system. Additionally, monitoring the battery’s charge level manually can also help prevent overcharge. Overall, building your own protection system for your 12V battery takes some research and skill, but can save money and provide peace of mind knowing your battery won’t become damaged by overcharging.
