Geely Cityray Battery Drains Overnight? Here’s How to Find the Parasitic Draw

If you're finding your Geely Cityray with a dead battery every morning, even after a good drive the day before, you're dealing with a parasitic draw — something is staying on and pulling power when the car is parked. Don't worry, this is a common issue on modern, electronics-packed SUVs like the Cityray, and while it's frustrating, it's usually traceable.

Common Culprits Behind a Parasitic Draw

In my experience, these are the first places to look on a Cityray:

• Interior lights (glovebox, trunk, vanity mirrors) not switching off
• A stuck relay — often the horn, wiper, or fuel pump relay
• Faulty alternator diode, which can drain the battery backwards
• The infotainment or telematics system not going into sleep mode
• Aftermarket accessories (dash cams, GPS trackers, USB chargers) left hardwired

How to Pinpoint the Problem

You'll need a digital multimeter. Set it to amps and place it in series with the negative battery terminal and the battery post. With the car locked and systems asleep (wait 20-30 minutes), the reading should be under 50 milliamps. If you see 200mA or more, you have a drain. Then:

• Pull one fuse at a time while watching the multimeter — when the reading drops, you've found the circuit.
• Check the fuse against the wiring diagram to see which component to inspect.
• For a more precise test, use a clamp meter around each wire.

Is It Safe to Keep Driving?

The short answer is yes, as long as you can start the car with a jump starter or keep the battery charged. However, repeated deep discharges will shorten your battery's life and can leave you stranded. A parasitic draw also can point to a failing voltage regulator or wiring issue, so it's wise to get it diagnosed before the problem gets worse. You can keep driving short distances, but don't ignore it.
