Is ther a Red Top battery that will fit in an 88 C4 properly?

Thanks John

Any other choices for a good battery that will fit properly?

 

don't like the Optimas

Have a new Interstate 75 fits perfect works great

 

ACDelco Professional grade (7 yr).

Will fit perfectly (remember to remove/reinstall the insulator foam wrap (or order it from Ecklers, etc if not on original).

Also, the ACDelco is designed to accept the higher-voltage charging rate of our C4's.

 

C4's don't charge batteries with any different voltage than other cars. Lead acid batteries have limits for charging voltage and C4 alternators stay within those limits.

 

Higher compared to what?

 

Thanks for the ccomments, went with the AC Delco, 7 year plan!

That's not true based on our Vettes and TransAm.

For example, on average, both vettes (and the TransAm) charge anywhere from 0.2 and 0.4 vDC above our Camry, given the same ambient temperatures and battery age.

Charging voltage differences as little as 0.2 vDC can make the difference between a battery gassing and loosing some 'acid' or not.

Noteworthy is that the GM cars originally came with 'maintenance free' batteries, whereas by example our Camry came with a traditional 'need maintenance' battery.

Also, Lead acid batteries are not all the same nor do they have the same ideal charging curves. For example, some true maintenance free battery has calcium added to help reduce gassing. This raises their gassing voltage and thereby their ideal charging curve.

Also, technically, AGMs, GEL, and spiral-gel batteries are 'lead acid' batteries, albeit the 'acid' may not be as liquid or the plates seperated differently. Nonetheless, very cleary documented by battery manufactures is the need for different charging voltages for these different 'technologies and the damage to them if charged higher than their ideal charging voltage (based on ambient temperatures). This difference can be as little as 0.2 vDC.

So, in my experience, the C4's (and C5's) Alternator's output voltage is higher than many other cars and is more designed for 'true maintenance free' batteries, like the ACDelco's. Hence my comments in my earlier post.

 

I like and use the red tops. I had a battery leak out and eat the paint off of my fender. That will never happen with the red top. Douglas

 

I had a red top and it lasted two weeks before leaving me stranded with no warning. It wouldnt take a charge after that either. I went back to a conventional battery and havent had any troubles. Also,my C4 alternator puts out 14.4 V, where as my last Camaro put out 13.8 V. I dont know if this is significant.

 

If you look up the upper and lower voltage limits allowed for GM alternators you will find that the range FAR exceeds the recommended charging voltages for the different style car batteries. Talking about 0.2 volts difference between cars is laughable in the light of the production voltage tolerances.
