so my battery is on the way to the graveyard on my 05 limited coupe and having hard time finding a battery. Diferent people say different things, some say the size is 48? whatever that means and others say the battery is different size? I dont know what to do, do different size batteries fit and work in a crossfire?

 

This is factory specs for our battery.

 

Interstate Battery MTP-H6 is an EXACT copy of ours. Check for one if they sell them in your area. I put one in my 04 before I traded it.

 

thanks got one the other day and my car is back to normal and doesnt do that thing where the spoiler comes up automatically, too bad Az is so hot that i heard it kills car batteries faster

 

Hey! I'm having weird spoiler issues too and I was told it was probably my battery which it turns out is finally running low (I have an '04, 48k in FL and it has never been replaced!).

Where did you guys go to get your batteries? Did you get Interstate MTP-H6 or Interstate-91? Thanks!

 

I went with a Bosch if that helps

 

The MTP-H6 requires no spacer to make up for the lack of height but costs quite a bit more.

The forum favorite is the MTP-91, it requires a spacer but is much cheaper and just as good really.

The battery style is 48R, the R means the terminals are on the right hand side when the positive terminal is at the rear.

Just as good? IIRC, the MTP91 has higher CCA so I would consider that better.

CCA is good but an increase in CCA comes at the expense of storage capacity weight for weight.

Higher CCA requires the use of thinner and more plates, thinner plates makes for a less robust battery, as there is more chance of shorting between plates. Thicker and less plates store more power.

The best battery for you has the best balance between storage and CCA that is good for your area temperature wise. The warmer the climate the less CCA you require.

Those 18lb batteries would be none to reliable in a Wisconsin winter but OK for Florida, but have any trouble starting with one in Florida and you would soon run out of power.

With batteries weight (lead) is everything power wise. You can store more power in a heavy battery and use it longer.

 

Ouch!
These suckers are expensive!

Alternatives???

 

Alternatives you ask!

Duh! I read 180's link after I posted!

 

The MTP-91 can be had for under $100 I hear down there.

Get out of the kitchen in that restaurant and do some serving in a short skirt and low cut blouse and make some good tips.

In other words get off your a$$ and show it.

 

Duh! Duh!
I read your post after you had posted that you had read my post after you had posted you first post..... I think.

If you have posted a new post before I get to post this post in answer to your post that you posted ....... well you get the idea.
