Lots of modern high performance batteries are sealed for life....you cannot check the electrolyte . But they should have a "Green" window button on them to indicate charge condition.Used to be the case you coukd check the fluid levels in the battery - the last few ive had show a coloured display to indicate the health of the battery (green = good, red = needs attention). In the colder weather, i check weekly along with tyre pressure and wipers.
I guess some people are too busy, or lazy, to run these basic checks.
