Aren't newer Hi-Tech cars supposed to be more "gentle" on batteries?

new cars have sleep mode. also have BCM, old cars have lights and stuff hardwired so if you leave the cabin light on it'll drain the batteryon newer cars the BCM will turn off the lights after some time
one possibility,
it's not the cars, but the batteries.
more batteries now are of the maintenance-free or less-maintenance designs.
their electrolyte levels are not as easy to see and not as easy to refill...
gone are the days when car owners would regularly peer into their batteries' innards to examine the fluid levels, and add additional fluid when necessary.
i imagine, many batteries now are prematurely dying because they dry up.
Some tech on new cars din ang culprit for the battery degradation.
My unit has red light turned on sa my side ng driver door if I opened the door.
That alone will eat up some juice of the battery.
Also, when unlocking the door, it will automatically turned ON the display gauge with a chimed sound even if hindi pa turned ON ang makina.
Including yung light indicator ng mga important buttons sa loob.
So kaya cgro hindi umabot 3 yrs stock battery ng unit ko.
Yung annoying lang sa unit ko is one of our family members forgot to close the glove compartment box.
Automatically mag turned ON yung light sa my glove box if nakabukas.
They forgot to close it sometimes, magdamag naka turned ON ang light which will definitely eat up some battery juice.
Also remember to check if you can "turn off" spare keys of your vehicle ... especially ones that have keyless lock/unlock feature ...
today's lithium button batteries can last 5 years or more. some even say 10 years. a far cry from the non-lithiums of olde.
photographers were one of the first beneficiaries of these long-lasting batteries, what with their habit of keeping camera equipment full of batteries for long periods of time, in their bags.
i do not know if using disposable lithium batteries from time to time, has any significant effect on their... relative longevity,
compared to if they were to simply hang there, unused.
non-lithium batteries, however, their shelf life is significantly shorter. 1, 2, mebbe 3 years?
this is from personal experience. on googling, there seems to be a wide range being quoted.

Back in the day, the Nokia 5110 (arguably the GSM phone that started the phone personalization era) had a battery life of about a week of typical use. Otherwise, it will only last a 'measly' 3 days if used heavily, like playing Snake every time you're bored. That was because it was hardly drawing anything while on standby.
This analogy applies pretty much to cars of yore compared to modern ones that could have between 5 to 150 computer modules or sub-systems. Each will draw a miniscule amount of current (quiescent current) even when inactive or in sleep mode. Some are easily woken up (or are always partially awake) like security systems, the proximity system for keyless entry, remote start, etc. Add to that any 3rd party accessories that are designed to have a dedicated B+ connection like audio amplifiers, standalone entertainment systems, etc.
That said, it has become somewhat necessary to maintain the battery at full/float charge when not in use for more than a day or two. This practice has worked for me but as always, YMMV.
Battery maintainer ba?
Choose your poison from Laz or Shopee. Just look for one that explicitly has the float-charge mode.
I use this to maintain the small 12V battery on my backup generator: LST Automatic 12V 750mA Trickle Battery Charger Smart Float Charger Maintainer for Car Motorcycle Lawn Mower Tractor
I use this on my Innova 2.5L Diesel: LST 12V 1.1A Car Battery Trickle Charger Maintainer 4-Stage Smart Float Charger For Car Motorcycle Lawn Acid Batteries
