C5 Z06 Corvette battery


Had the  delco anyway. It's Z06 higher compression, 405 hp so need enough cranking amps. When the delco went I put in an Optima, the 6 pack looking ones. 1st went bad, now the second went bad! Drained pretty low in winter could have done it but I don't disconnect since some times we get awesome days even in winter. Not even going to mess with warrantie if there is any left.

I use interstate in my trucks. What do you recommend? Delco again or a local shop and one with enough cranking amps?

The Gel-Cell Optima batteries always die over the winter and do not do well unless they are in constant use. Even then they are spotty and I see a lot of people have problems with them.

Interstate is a good battery also, however Delco would be better because your vehicle is a GM Corvette and that exudes more "factory fresh" vibes - plus they are good batteries!

Just whatever you do, don't get an AutoZone duralast as their warranty is not good. 

My Delco battery has done very well over the long winters and has sat for months on end thru the winter without issue. I'd go the Delco route because you got a GM car.

Gel-Cell batteries like the Optima are more geared for off-road, boating and other applications that require offset or odd mounting. They look cool as all hell, but they hate to sit. 

I will say Optima has always been good about their warranties, so if you still have a warranty I am sure a new one would get you thru the summer but you'd have to get a battery tender for it or disconnect it over the winter.

Thanks Sell. Not satisfied at all with the oprimas now I understand. I'll probably go delco again just to stay stock. Whole Corvette screams stock, awesome gotta keep it that way I guess. Delco can't const much more than an interstate anyway. However I do love interstate. Had them in my commercial lobster boat too, 2 of them Detroit 4/53, 4 valve head. What a cool setup that was. Interstate in my F350 too. Which reminds me, VERY hard to shift. I'll pull the inspection cover under the column and look. Think maybe the sensor on the tranny where cable hooks up. Funny, it was fine, sat 3 weeks then HARD to shift.

It's the cable making it hard to shift.

Delco stuff isn't cheap, but should be inline with Interstate's Magatron offerings. I know in terms of resale (not that you're selling) the Delco would be seen by many as a sure sign the car see's quality factory parts.

Think the cable or the sensor thing on the side of tranny? On my 2003 F350 4x4. Guess time to go under the truck again. I'm pretty good at fixing, just so tired of it. I'm old, 65 in NOV, just tired of it.

I agree, the delco should not be more than an interstate. And in my experience just as good.

I have a Hustler Raptor zero turn mower, 5 years in July. Battery getting bad but sometimes jump, sometimes not. NOT BAD for a almost 5 year old garden tractor batt!!! I get one shot, full choke, full throttle and in 5 days usually work. Miss it, jump it.

I mean damn, got 14 or more internal combustion machines, full time job keep them all running!!!!!!!!!!!!!!!

That's called the transmission range sensor, and they sometimes seize up. If you disconnect the cable from it you can see if that is what is causing the issue. In the event you find it is actually the sensor you should replace the pigtail connector too.

Usually the range sensor will break well before it gets a chance to make shifting hard... It's pretty much a string! So I am willing to bet it's your cable but you should for sure check it first.

Thanks Sell and PS, good info. I'll pull the inspection plate under the column for shits and giggles be sure everything OK, but cable or sensor prob the culprit for sure.
