Bad 12V battery??

[suchham]

By this October, my 12v will be 5 years old. So far, I've seen no drop-off in mpg or any other indications that it's failing, BUT it has not been tested yet. Since I'm taking a long trip in September (~4000 miles round trip), my thinking is it's time to replace it anyway. It would probably conk out this winter, if not on the trip, and why wait for that to happen?

Hi Suchham;

Very wise and overall good policy.

In fact, my 2006 HCH still had its original battery on and it tested great year after year.

However, I decided to replace it before I sold the car a couple of months ago primarily because I wanted the experience of its new owner to be as flawless as mine was during its 5 years under my care.
So far, the new owners are loving the car and I certainly do not mind that one bit.


Cheers;

Today is the first day with a new 12v battery. I just got back from the shop and a freshly filled tank o' gas. Now I'll see what difference the new 12v makes. Just judging from the trip home, the mpg is gonna be up and the SOC seems to stay a little higher than before. It's now sitting at about 6 bars where it was staying at 4-5. It also seems that it's easier to keep the iMPG above 50 and the car seems to have more pep. I'll take that.

At any rate, my D51R has held up very well over the last 8 months or so and solved my issues with consistently low IMA charges and daily crashes.

So, even though 3 auto parts sights I have been to say this battery is not a correct fit, it will work, yes?

Well, it's debateable... see my thread about flashing dash and dead car... the OEM battery lasted a good while, the aftermarket D51R (which does fit... barely) wasn't so hot. At least at my dealership, they use batteries with a 100 month prorated warranty.
