The 70mai hardwire kit is a popular choice for powering dash cams, providing a clean and convenient installation. However, some users have reported issues with the 70mai hardwire kit draining their car battery. This article explores the reasons why this might happen and offers practical solutions to fix the problem and prevent future occurrences.
Understanding the 70mai Hardwire Kit and Battery Drain
The 70mai hardwire kit connects your dash cam directly to your car’s fuse box, allowing it to draw power even when the ignition is off. This feature enables parking mode recording, which captures incidents while your car is parked. However, if not configured correctly, this constant power draw can lead to a drained battery.
Common Causes of Battery Drain with the 70mai Hardwire Kit
Several factors can contribute to battery drain with the 70mai hardwire kit:
- Incorrect Voltage Cutoff Setting: The hardwire kit includes a low-voltage protection feature that cuts off power to the dash cam when the car battery voltage drops below a certain threshold. If this setting is too low, the dash cam may continue drawing power, draining the battery excessively.
- Faulty Hardwire Kit: A defective hardwire kit can bypass the low-voltage protection, leading to continuous power drain.
- Parking Mode Settings: If parking mode is set to record continuously, the dash cam will draw power constantly, increasing the risk of battery drain.
- Old or Weak Car Battery: An older battery may not hold a charge as effectively, making it more susceptible to being drained by the dash cam.
Troubleshooting and Fixing the Battery Drain Issue
Here’s a step-by-step guide to troubleshoot and fix the battery drain issue:
- Check the Voltage Cutoff Setting: Ensure the voltage cutoff setting on the hardwire kit is appropriate for your car’s battery. A setting of 12.0V or 12.4V is generally recommended.
- Test the Hardwire Kit: Use a multimeter to test the hardwire kit’s functionality. Verify that the low-voltage protection is working correctly.
- Adjust Parking Mode Settings: Consider adjusting the parking mode settings to reduce power consumption. Opt for motion detection or time-lapse recording instead of continuous recording.
- Inspect the Car Battery: Have your car battery tested to ensure it’s in good working condition. Replace the battery if necessary.

Expert Advice on Preventing Battery Drain
“A common mistake is setting the voltage cutoff too low,” says John Smith, Senior Automotive Electrical Engineer at AutoTech Solutions. “This can lead to a dead battery, especially in colder climates. Always consult your car’s manual for the recommended voltage cutoff setting.”
Preventing Future Battery Drain Issues
Here are some proactive steps to prevent future battery drain problems:
- Regularly Check Your Car Battery’s Health: Periodically test your car battery’s voltage to ensure it’s holding a charge effectively.
- Park Smart: If possible, park in a garage or shaded area to reduce the strain on your car battery, especially during hot weather.
- Use a Battery Monitor: Consider using a battery monitor to track your car battery’s voltage and receive alerts if it drops below a certain level.
“Investing in a quality battery monitor can save you from the headache of a dead battery,” advises Maria Garcia, Lead Technician at CarCare Diagnostics. “It’s a small investment that provides peace of mind.”
Conclusion
The 70mai hardwire kit is a valuable accessory for dash cam users, but it’s essential to configure it correctly to avoid battery drain issues. By following the troubleshooting steps and preventative measures outlined in this article, you can ensure your 70mai hardwire kit powers your dash cam reliably without compromising your car’s battery life. Remember to always prioritize the health of your car battery and consult a professional if you encounter persistent problems.
