I agree. My reading indicates an older battery puts strain
on the alternator.

I too say I can tell this with my 91 Civic (original owner).
In fact, in 2000 before I knew too much about the
alternator, charging, and battery systems, I noted that the
car had been starting with difficulty for several days prior
to it dying so much that it would not start the car.
My 91 Civic is on its fourth battery, though I will likely
replace it pre-emptively sometime late this year.
Do the five checks listed at
http :// honda.lioness.googlepages,com /battery%26alternatortips
to get a handle on how your system is doing. If the battery
voltage is over 12.5 volts with the engine off and no
electrical loads (like lights), it's probably fine. If it
has been jumped a few times, consider replacing it
pre-emptively.

The heat's by far the worst.
