The last couple days I've noticed that it takes a couple extra cranks of the engine before it completely starts. Could this be a battery thing or something else?

My guess, your battery needs charged and/or replaced.

A 12-volt battery will measure at about 12.9 volts when it’s fully charged and about 11.4 volts when it is fully discharged. Measure with a voltmeter across the battery. Then, charge battery first, if it won't hold a charge, get it load tested and replace if necessary.

Load testing is the true way to tell a battery's condition. Anyplace that sells batteries will normally do it for you for free.

C5's use a lot of current when sitting, consider using a battery maintainer when your C5 sits for 3 or more days without driving.

Car is my daily driver so I don't see the need for a tender. At most it sits 10-12 hours.

My '99 would do that as well when the battery started slowly dropping off. Replaced it with no more problem.

Guess I should go ahead and get that yellow top I've been looking at for my audio upgrades. Anyone know the best place? Who's done the big 3 upgrade? I should probably do that while I'm at it.

First time I used a Costco battery which was fine for years, then used a Sam's Club battery with the same good results. Saw too many posts in here where people got worthless yellow/red top batteries.

Do a search in the FS section, There was a vendor that had a great price on the Red and Yellow top batterys..

Mine seems to be doing it occasionally now. Will keep an eye on it. I bought the car in January so not sure how old the battery is. It is an Interstate. Could have sworn I've read on the forums that it can be a tough to swap out the battery. Any truth to that?

Mr.Bill

Changing the battery is cake, Takes maybe 5 mins..

swapped mine out with a red top, and had no problems. Unbolted and removed old one, put new one in and everything worked. Went with red top cause it's a popular swap in off road community, where occasionaly a battery will get upside down. I've had good luck with them.

i've had a yellow top in my 78 pace car for years and it has been a great battery. since it is inside the car it made even more sense to go with a gel typ rather than a lead acid type (fumes and all that, lol). i wouldn't hesitate to replace the battery in my 04 with another yellow top in the future.

If you put in an Optima Red or Yellow top, be sure to use the correct spacer provided with it. You can crack the bottom of the case if you don't.
