Why should you want to upgrade the battery in your Mustang? It seems to work "ok"
and it's only a couple of years old! Well things are not always what they seem.
Problem Number One:
Corrosion creeps up the cables under the protective coating where you
can't see it and causes extensive damage. In addition, corrosion is eating
away at the bottom of the battery tray under the plastic. You don't know
it's happening! This happened to me on my 94 Cobra after only 10K miles.
The corrosion had eaten away the cables by almost a full 12" from
the terminals and it cost me $75.00 to replace them.
Problem Number Two:
Regular Flooded batteries are ticking time bombs. I had fully restored
a muscle car and I put a regular flooded battery from an auto parts store
in it. I had less then 100 miles on the whole thing, when one hot afternoon
I went to start it and I heard a muffled pop from under the hood. Needless
to say the car did not start and when I checked under the hood, I discovered
that the battery had exploded and battery acid was dripping all over my
brand new engine compartment and my highly polished motor. Acting quickly
I grabbed some baking soda and neutralized the acid. But no matter how
hard I tried within days the paint and chrome was peeling. Think this
is a rare occurrence? It's not! Batteries produce hydrogen and any spark
could set it off. Luckily, I was not working under the hood.
Problem Number Three:
The life expectancy of an average battery is 2-4 years and there is never
any warning when they go bad and will not start your car.
I learned these things the hard way and I searched for a product that would solve
these problems. After talking with several hot rodders, I discovered the
Optima Battery. I talked with people that have had them in service for
more then 10 years! From that point on, the first thing I would do to
any project car is put an Optima Battery in. As it turned out, I ended
up working in the battery industry and I can tell you that I have sold
thousands of these batteries and it is by far the best battery you can
This battery can be mounted upside down, dropped, and even cracked wide open and it
will not leak a drop of acid. Zero corrosion on the terminals. Made with
spiral wound technology, its separators hold all the acid against the
plates (kind of like a saturated roll of paper towels). The battery cannot
explode and will not sulfate. Its life expectancy is 3 to 5 times that
of the best flooded batteries.
I installed an Optima Battery Model 35/75-925 in my 2000 Mustang. This particular
model is new for Optima and it is much smaller and less expensive ($125.95
Street Price, cheaper then the previous model 800U ($139.95). It has 925
Cranking Amps (about 200 more then the factory battery).
The battery will fit any year mustang following the simple hold down modification
and install instructions below:
