バッテリー寿命延命装置とはどういう物か調べてみました

There are many devices on the market that claim to extend battery life simply by connecting them across the battery terminals. Since these devices are hard to believe, I used an oscilloscope to observe the waveforms. They appear to emit a pulse for desulfation, but is this harmless to electrical components? Will this device consume battery power when the engine is not running? There are many concerns. Here, I investigated these issues using a tester and waveform observation. The product used for the test was the Elma System Nobita. Similar products include the BX-10 Thunder UP, Battery Refresher HBR-1000, SEKIYA DSCharge, and the iBI (Ivy) Battery Life Extension Device for 12V Batteries iBI-FS12V.
