If you’ve owned your 5th generation Honda Odyssey for at least a few years now, you’ve most likely had your battery die on you. Not only are the original car batteries on these vehicles notorious for completely losing charge only after 2-3 years of use, but they tend to get drained if you happen to leave your car on (car on, but not running) for a short length time. Car batteries generally range somewhere between 2-5 years, so it seems the OEM battery on the Honda Odyssey seems to die a bit sooner than the norm.
