if a battery needs replacement, assume any make/model of a car, how important is it to
purchase the OEM battery or will any similar CCA rated battery, sized properly fitting
into the battery case under the hood, be acceptable?

when purchasing a battery from any of the larger national outlets, they always have a
couple options where the CCA is precisely the same as the OEM battery but sometimes
they also have a little cheaper (maybe for $20 less) model available that has a lower
CCA rating.

if the CCA rating does not match precisely the OEM CCA rating, what are the issues to
consider?

I understand that for winter and cold weather startup, the CCA can be very important
but what about more moderate climate where there are no subzero temperatures?

is there a universal rule that under warranty, only the OEM battery can be replaced
with another OEM battery ?

Get a battery with the largest CCA rating available that will fit into the
space. If your car is fairly old, batteries have improved, and you can get
a higher capacity battery than the OEM one. This means the battery will
last longer, effectively.

Do not ever get a lower CCA rating. Batteries get old, and they degrade,
and you want one that can degrade as much as possible while still starting
your car. An oversized battery is a win.

If you have more capacity than you need, the battery can degrade more and
still be okay, under any conditions.

If you are in a place where it gets very hot, or a place where it gets very
cold, you might investigate special batteries designed for those conditions
also.

Sheesh, if the car is under warranty, get the dealer to replace the battery
on HIS dime.

All that makes much difference is that you get one that physically
fits the space and has the same or better CCA rating. My experience
with "bigger/stronger" batteries is that they don't last any longer
then "normal" capacity ones. I buy whatever has the best combination
of warranty/price. I don't think the warranty on the car will be
affected by your choice of replacement battery, it would be a real
stretch for the dealer to make any connection.

The most important thing is to get a fresh one. Batteries don't like to
sit on a shelf.

thank you for all replies.

the reference to warranty was due to a local dealer performing a recall/warranty
service (toyota) and upon finding a non-OEM battery they claimed to owner that entire
warranty has been voided.

according to their words ".... the higher capacity/CCA battery has caused (components)
to be fried... "

there are no issues with the car, nothing is broken

the owner is simply having car checked according to the letter where dealer adjusts as
needed the acceleration related components.
