What is draining my CRV battery?
Why the Accord and CR-V Batteries Keep Dying The batteries are contending with a parasitic drain, which happens when an electrical component continues to draw power from the battery even after the vehicle is turned off. Even a slight draw can empty the battery if left unattended for a couple of days.
How to find the cause of parasitic battery drain?
Luckily, you can usually find the cause of a parasitic draw yourself. Start by connecting a digital multimeter to the negative battery terminal of your vehicle. Then, remove the fuses one at a time while watching for changes in the multimeter’s reading.
How often does a Honda Civic battery drain?
The drain was changing between 0.22A and 0.5A every few seconds. As far as I know it should be around 0.05A. No wonder why the battery went flat in such a short period of time. Now I need to investigate this further, taking the fuses out one by one. Any bets?
Where is the parasitic drain on a Toyota Corolla?
Most vehicles have more than one fuse panel. This one, on a Toyota Corolla, is located under the dash on the driver’s side. After pulling each fuse, observe the multimeter display to see if the amps drop. The fuse that reduces the amps is where the parasitic draw is located.
