Battery info

My factory Delco battery is getting slower and slower at turning my truck over every day, so I'm looking at getting two new batteries to replace the single one that's in there now...

My question is, what's the biggest battery you can stuff in there?

Whenever I replace the factory battery, I always get the most CCA possible... It's even more important now, as I won't likely be able to plug my truck in at home.

I know the extra power will be nice when I get my stereo installed, and when towing a power hungry trailer...

Also, my lights tend to dim randomly, so either my alternator or battery is on the way out... I'd rather change the battery before it takes out the alternator

Interstate has a 980 CCA in that size. Great battery.

What's the size of the battery?

Batteries are expensive as fWONk to ship, so I'll be buying locally... We've got a good store that's given me good batteries... I ran my stereo in my '85 S10 for 3 days straight and it still fired right up

I think it's a group 48H6. Lemme look

Yep group 48.

And the Interstate is 970 CA not CCA. The CCA is 770, but I have had this battery sit for 2 weeks and start my truck at -30*

Great battery for cold weather

I haven't looked too close at it yet... But WTF is up with the big bar of a positive battery lead?

Is it just a fancy top post clamp?

Part of the cable, not the battery. Good for jump starts

Actually, for the most part it makes it more of a PITA... At least while keeping the red plastic intact

But it's nice to know that the battery location will clear a top post battery


I might actually ditch my normal battery shop for some Exide Orbital's, they seem to be decent...

I find it slightly disappointing that my '85 S10 had room for a bigger battery than both my Blazer and my Sierra

Anybody have luck putting a group 34/78 battery in a GMT900?

Look into Auto Zone I think it's the yellow top my buddy has one that's nine years old.
