The FIXD OBD2 module does not drain your car battery. However, it can trigger other electrical circuits within the automobile. This may lead to parasitic draw, which can cause battery issues. To maintain car battery health, regularly check for these draws and any circuit problems to keep your battery functioning well. While FIXD will not … Read more
A battery in a circuit does run out of charge. As it discharges, energy to push electrons decreases. Self-discharge happens even when not in use. Voltage drops and internal resistance increases, making the circuit non-functional. A rechargeable battery needs recharging to restore its charge and functionality. Voltage measures the difference in electric potential between the … Read more
Charging a battery does not change its weight. During charging, a chemical reaction redistributes materials inside the battery. The process adds no extra mass and removes none. Therefore, the total weight stays the same before and after charging, ensuring accuracy and clarity in understanding battery behavior. However, some theoretical concepts suggest that there might be … Read more
A battery charger cannot jump start a vehicle. It recharges a flat battery but lacks the high current needed to start an engine. If jump leads fail, check the alternator and battery connections. A charging system issue may prevent power flow, requiring further inspection of the battery and current supply. When jump starting fails, often … Read more
