Most automotive wet cell type batteries will usually fail catastrophically. The low voltage condition indicative of a 1 bad cell often goes unnoticed by the average driver but is often the precursor to a dead battery. In the catastrophic failure, the cells collapse internally (often while your driving while the alternator is providing the power so you'll never notice). Then, when you try to restart the next time, nuttin'...
the cells in tip top shape.
A book could be written on lead acid battery maintenance...
I care for all the lift truck batteries at work.

I have replaced out 2 batteries since owning my car. I think the only small warning was it took a couple of cranks to start, which happened only a couple of times. Thankfully, both times the car battery died, it was in my garage. When I attempted to start the car, I would hear a real loud fast clicking noise. If you hear this, it's time to get a replacement battery.

You want a lesson on batteries, get yourself to an olde GATO or similar class WWII submarine museum and see if anyone there actually served aboard. THEM guys... know their batteries!
Interesting though... the "equalizing charge" idea. Like a 2 amp trickle over-night?

turn the charger off once 15V has been obtained.
I also have an adjustable turn on voltage via another
741 op amp.
A highly modified battery charger of sorts.
Nothing electrical/electronic goes unmodified in my world.
