I purchased a 2018 CRV, EXL 1.5L in September 2018. Within a couple of weeks of owning the vehicle, I decided to add a dash cam which is tied to a circuit that is powered with the engine off. I never had any dead battery issues until December.
Around December, my car sat in the garage for about a week at a time. Weekly, I would take the CRV for a 10-20 mile ride. I attempted to start my car the third week, and the battery was dead. This seemed to be an on-going occurrence.
In February, I had an aftermarket sound system installed, the amp used was a JBL Club-4505 (if that helps) and it powers off when the vehicle is not on.
I kept playing this game with charge and die. Finally, I took my car to the Honda Dealer which I purchased it from to try and figure out what the issue was. Their initial response was aftermarket, aftermarket, aftermarket.
I was told by the tech that the CRV takes about 40 minutes to cycle down after it is shut off and since the car has multiple computerized devices that take power, 5 days to a week of the car not being used will cause battery drain enough not to power the vehicle.
The dealer conducted a battery test, and it is rated for 410 Cold Cranking Amps (CCA) and it measured 499 CCS. The voltage was 12.46. The tech told me that the drain was about .41 or so. He said that is ok, when it gets above .50 then there is a problem. There were also no dead cells.
The other day, I have my normal routine, drive to and from work, the next day my battery was low enough I could not start the vehicle.
Upon calling the dealer again, they agreed to replace the battery. The dealer told me that sometimes aftermarket devices keep devices on even though they are off.
1. What are your initial thoughts?
2. Could the alternator not be providing the battery charge when I am driving since my aftermarket camera and system could be using it
3. What aftermarket replacement battery do you recommend? I was looking an Interstate MT-51R or a Yellow Top D51R?
4. Do you have any opinions/feedback/reasons not to use the Yellow Top? I don’t have any experience with them.
5. Any other suggestions?
