"A jumpy battery will cause the fuel pressure to fluctuate because the fuel
pump depends on a constant flow of current."
You do realize that the main function of the battery is to start the
vehicle, after that, the alternator takes over to power all electrical items
and recharge the battery. So I don't see what you're saying, unless the
voltage regulator is starting to go.
I've been using batteries purchased from Wally world for the last 5 years
and haven't had a problem. When 1 crapped out, I took it in for the
pro-rated warranty and got a replacement. I do my own voltage checks &
repairs, so I just get the battery there for the convince. I used to go to
Sears but they're 4 times the distance away and there's always a lengthy
wait, either in the sales line or the pick-up line in the shop.
"I later discovered that my other battery in my car is fine", maybe you
should have checked the charging system 1st, before deciding to purchase the
battery. Who would you be complaining about if you had decided to purchase
a replacement alternator 1st, then found out your battery or starter was the
problem. Most auto-parts stores I go to have a no return policy for
electrical items unless they made the error. Then you'd be stuck with an
alternator you didn't need. That's why I always pull the defective part and
take it in for a side by side comparison to make sure I get what I need.
The main point here is to check things 1st, before committing to the
Wasn't the engine running while you were testing the battery? It has
to be a defective voltage regulator that is causing this problem. A
defective voltage regulator can cause the voltage to vary as you
A battery can't do what you describe on it's own with the engine not
running. About 13.2 volts is the most you can get out of a car battery
unless the engine is running.
"Yes, I tested the Wal-mart batteries while the engine was running on the
How did you test the battery on the road? Were you running along beside the
car with the voltmeter clipped on? And how did you test the current flow?
How many amps did it put out? Do you know the difference between volts and

There are three primary makers of batteries in the US. All of them make
Everstart batteries for WalMart. You are saying that nobody makes good
You don't know what you're talking about. And as someone else pointed out,
there are no, repeat NO, returns on used electrical components. You made a
mistake. It cost you the price of a battery. If you want your money back,
put a classified ad in the local paper and sell it.

Yeah yeah... I don't know what I'm talking about but I beat many
scientists/engineers out there. Two years ago, I was the one who doubled my
Mercedes E320 45-MPG, and my Infiniti's 50-MPG. I am laughing at you men of
arrogant. Don't you know I got speedy tickets because I abused the free
energy I got, Yup! free energy for me, big bills for you arrogant....
Thanks to God for his generosity, I will let you suffer from your oil
BTW - I changed my name to Mickey Mouse so you can laugh at me further, ok?
If you are so smart, why didn't you check the charging system before you
bought a battery? And now you bitch about not being able to return the
battery? And you want me to think you are smart?
Just how did you double the mileage of your cars? The same way you checked
your battery? I would like to see your math on how you figured the gas

There's a reason that some batteries have a handle built in!
I don't know about 'jumpy', but my wife's car (RX300) went into the body
shop after she let her sister drive it. The new Interstate battery must
have been discharged, because they stuck a 'W' battery in it.
I did not notice until later.
Less than a year after, I ended up buying another Interstate (no
commission (sic) here) battery.
No problems now!
(It's no fun flying back from out-of-town to find the battery is dead in
rental parking with no electrical accessories left on. It tested bad on
a Midtronics tester!)
