Ellis Gibson (B.Sc. in Mechanical Engineering) A faulty throttle position sensor (TPS) can drain a car battery. It may send wrong data to the car computer. This can lead to symptoms like poor acceleration, rough idling, or stalling. Additionally, if control modules stay active when the engine is off, they can also drain the battery. Check the TPS for issues. Common … Read more
Faulty glow plugs can cause battery drain indirectly. If the glow plug relay stays closed, it keeps the glow plugs on, leading to high current draw. Normally, glow plugs work for 10-15 seconds during ignition. A defective relay can prevent them from turning off, so check it if you notice battery voltage issues. The primary … Read more
Yes, you can charge a warm NiMH battery. The optimal charging temperature is 25-30°C (80-90°F). During charging, the battery may heat up due to chemical reactions. A 10-20°F rise above the ambient temperature is normal. Smart chargers stop when the battery is fully charged. Do not exceed 55°C to ensure battery safety and prevent damage. … Read more
You can charge a lithium-ion battery safely at temperatures between 0 to 45 degrees Celsius. “Warm” means touchable temperatures above room temperature. Charging a warm battery is generally safe. However, avoid prolonged exposure to high heat. This can impact battery safety and performance over time. Charging a warm battery often results in a trade-off between … Read more
A faulty door latch can drain a car battery by causing an electrical draw from a malfunctioning door actuator. Symptoms include battery discharge overnight. You can conduct a parasitic draw test to locate the source of the drain. Troubleshooting this issue is vital to ensure good battery performance. Common causes of a faulty door latch … Read more
Yes, you can charge a warm lawn mower battery. Use a smart charger with the correct voltage and amp settings. Connect the positive clamp to the positive terminal and the negative clamp to the negative terminal. Choose a slow charger and avoid extreme temperatures to help extend battery life. Before charging, check the battery’s temperature … Read more
A faulty cable can drain a battery by creating a short circuit. Exposed wires and burnt insulation may cause an electrical discharge to the negative ground. This ongoing discharge gradually weakens the battery, leading to performance issues and potential vehicle reliability problems. Additionally, short circuits can occur due to damaged insulation on the cables. This … Read more
Emergency brakes work mechanically and hydraulically. They do not use electricity when activated. The vacuum servo operates only with the engine running. Thus, the emergency brake does not drain the car’s battery. In short, the answer is no; using the emergency brake will not affect the battery power. Myths about parasitic drain in modern cars … Read more
You can charge the VEX IQ battery while it is in the VEX Controller. There are two methods: 1) Use the USB cable to connect the Controller to a USB port or a USB phone charging adapter, or 2) Connect the Controller to the Brain using the provided Tether cable. Monitor the charging process closely. … Read more
Electric windows can drain the battery because of a parasitic draw. This happens when vehicle components, like power windows, use energy even when the vehicle is off. Other systems, such as the radio and clock, also contribute to this battery drain. This can impact the overall energy consumption of the vehicle. Typically, if your vehicle’s … Read more
