A parasitic draw on your CS35 Plus can leave you stranded even when everything seems off. Start with battery health, charging, and a key-off current test before chasing modules.
First, Don’t Assume It’s a “Bad Battery”
On a Changan CS35 Plus, an overnight dead battery is often a parasitic draw — something staying awake after the car is locked. That said, start simple: have the battery load-tested and check the alternator’s charging output. A weak battery or a failing alternator diode can mimic a draw, and a battery that has been flattened a few times may no longer hold a charge. If the car is still under warranty, document the concern before you start pulling fuses.
