This video shows a practical power test of a 12V DC battery using a multimeter to measure voltage and current under load. It demonstrates how much current a 12V battery can actually deliver and why handling high-current batteries requires proper safety.
The test is focused on real results—no heavy theory—making it useful for DIY electronics projects, battery packs, DC systems, and beginners learning practical power testing. Watch till the end to see the full behavior under load.
