Sudden battery discharge on 2023 CX-5
Found the answer on another forum What this guy’s wife did is no doubt same thing mine did. Let this be a lesson for all who think that everything shuts down in a CX-5 after 30 seconds! (Especially a current vintage example) And a sidebar for Callisto: See how productive and helpful a civil exchange on one of these forums can be!
And as for how I post maybe you should read my responses a little more carefullyu. Go back to the begining. Oh wait I will save you the trouible her is my quote. See anything that is importamnt information about youer concern about the power drain?? rolmao!

I might add that a description STONE DEAD is not exactly a good one. There needs to be a bit more like the engine would not turn over, there were no dash lights no interior light ect... but not stone dead. Do the math if the battery was hot charged @ 13.50+ volts while it was running and stabilized to 12-1250 after you tuned off the engine. A voltage drain in 4 hours is a LARGE drain if there was no power to anything!

I have a late build 2023 - 6/23 - and It was one of the last 23s since 24s are coming in and the only 2023s left are on the floor or trickling in thru the pipeline - but no new 23 builds - So im curious Where was your 5 made - Hofu or Hiroshima ? Whats the trim - You said build was 1/23 -
I couldnt find a TSB -because
A TSB is issued when there have been enough complaints about a certain issue affecting a specific type of car, but the issue is not safety- or emissions-related. Basically, the manufacturer sends out an advisory about the recurring problem to dealership service departments.- but none I could find - it would seem this would fall under " safety related " but hey ?
Thanks keep us posted !

All batteries are not manufactured equally.
To find the best ones, check-out independent labs who test them.
They do all kinds of test to determine probable longevity, how quickly they can drain power, their reserve power, cranking amps, etc.
They do this under all kinds of weather and electrical discharge conditions.
I can say I've never seen a standard OEM battery in anything make any testing labs "best" list.
Vehicle manufacturers are no different than any other manufacturer.
They will use the least expensive part whenever engineering and the bean counters deems it feasible.
Tires and batteries are generally deemed as such.

It is the coded number that is melted into the top cap on the side of the battery. You need to go to the manufacture of the battery to decode the actual production date.
I believe it depends on the market, the model. At least this is what I have been told and seen from a few auto manufactures that I have friends head of several departs.
But it is a great internet myth that is often told.
Batteries have way to many recycled materiel now and it is hard to find 100% new material batteries. IMHO this has affected there dependability. But that is an opinion based on how many of all brands I replace in less time than they should be going bad every day and week each year at the shop.
I have read those battery test and they have a slight flaw if you go read them and take your "TIME" to figure it out!

I meant the build date of my car
