Battery dead--no fix available REALLY?

I too have experienced the 2012 Honda CRV dead battery syndrome. I have been stranded 4 times with essentially no battery drain on the system. Been dealership three times.....battery is fine they say.....no parasitic drain they say.....no need for a battery replacement they say......latest computer software update will fix the problem (they gave up on saying)....now Corporate level Honda says they only advice they can give me is to return to dealership to let them try to fix it again. REALLY??? When will they start paying me for my time? I have been a long time Honda owner....but never again. No known fix from a company that manufactured the car???? This is inexcusable. Honda has denied my request to pay me fair market value and take back the car. I am stuck.... Buyers beware and stay away from Honda. I have purchased a new battery at my own expense AND a portable battery charger so that I won't be stranded again.

Some of the first questions that must be asked are:
How often is the car driven?
How long or far is the typical trip that the car is used for?
What accessories are commonly used?
Is the trip primarily on highways? In traffic? Stop and go, with a lot of idling?
How long after a battery is replaced will the car start correctly before it acts up again? (a week, a month, several months?)
Are there any other issues with the car where something works intermittently or not at all?
Once the car acts up, how long is the battery being recharged, and then how long is it until the next time the car presents with the battery dead?

There are other products that are much better suited for sealing the battery connections.
By chance has your normal trip changed in the last two years? Do you maybe drive a little further, or have the traffic patterns that you encounter changed?
The three hour wait is necessary to see what the batteries actual state of health is. When you are driving the battery would be getting charged, and that would result in a higher measureable voltage due to "surface charge". That surface charge will dissipate after a couple of hours and the battery's true state of charge can then be measured.
A battery at 100% state of charge will be 12.65-12.7v
A battery at about 85% state if charge will be at 12.6v
A battery at about 50% state of charge will be at 12.25v
A battery at less than 20% state of charge will still start your car, but its at rest open circuit voltage will be just over 12v.
If you measure 12.3v or less, the battery needs to be charged even though the car still starts. If the battery doesn't get charged, it will be sulfating and be getting ruined by being left in that discharged state. This will show you if there is still a problem or not, but and here is the tricky part. It doesn't necessarily mean that the car has a problem that needs to be fixed.

And for the really tough cases, overspray with NOCO aerosol.

Oh, and I consider checking the integrity of my battery connections as just a normal part of routine maintenance on our cars. And I can't remember the last time I found anything amiss regarding tightness. But I did find nice cauliflower growth under the red cover of our old Outback from my periodic inspections a few years ago. Baking soda and a wire brush, new pads and some spray, and all was well for the remaining few years I owned that car. But looking and checking likely puts me in the minority. I get that.
