Unfortunately I haven't got access to a voltmeter or any way to diagnose any electrical leaks, and found out that my battery is completely drained from not driving for about a week. Some dash lights will light up if I turn the key to the ignition position, but there's no click and the engine will not even try to turn over even if I try to jump start it.

I know that my BT module went bad like 2 years ago and Acura service removed it. I went to check the HFL module just now, and found out that they apparently disconnected the module too (the green plug) so I'm guessing that common cause can be ruled out as well. Any other ideas on what the drain could be? My Acura service dept appears closed indefinitely, I'm guessing due to the pandemic although I thought they were an essential business. In any case, I'm going to get a new battery but I don't want that thing drained after a few days so if there's a way I can drive the car in "safe mode" while I wait for Acura Service to take a look at it, it would be appreciated.

 

How old is the battery? It's known that batteries just don't last long on these cars.

 

Actually, it's about 3 years old at this point. I did notice it a little slower to startup when the weather started getting cold a few months ago, but did not have any serious issues.

What's a "typical" battery life on cars (if there is one), and what's expected on these?

 

Lots of people here report that batteries just don't last very long on this car, perhaps like 3-4 years at most? Just today, I had the battery replaced on my RL due to slow cranking if it sat for two days. The dealer load tested it and found it needed replacing. Since they have a 100 month warranty, the new battery was free.
