Stock Battery Specs????? - Diesel Forum

RDBillsJr · 04-10-2005, 10:02 AM

My batteries are getting weak. Time to replace them.

The previous owner put in Delco Group 24 675cca marine starting batteries. (Lasted 7 years, so I can't complain.) However, the battery trays look like they take Group 27 batteries.

What are the stock battery specs (and size)? Whatever I put in, I want to be sure the specs exceed stock.

You need more power. 750 amps, cold cranking at least. Group 27 sounds right.

A lot of us are using the Wal-Mart Maxx batteries (65N) They're about the best price, have a 3 year free replacement warranty, and seem to hold up pretty well. They're also rated for 825 CCA if I remember right.

FYI 850CCA is the bare minimum per battery, Wally mart has 1000CCA I believe pretty reasonable. Don't get confused by seller gobledygook as to CA (cranking amps) and CCA (Cold cranking amps) this is probably one time where more is better.

EDIT Do check the cable conditon closely.........

Cool. Anyone know how the 1000cca WallyWorld batteries are labeled?

My truck is a Group 65, If you go to the many websites you will see competitive batteries at 850CCA.
Sams Club under $50 each

I just replaced my batteries after have a hard starting winter..

I bought Group 65 batteries from my local CAT dealer. 1100CCA $70Kanuk each.

I also replaced ALL my cables. 2xGround and positive. larger wire than stock and cleaned the areas to ground. $150Kanuck (built my own with parts from the Freightliner dealer (they had cable in stock)

What a difference!

I put 2 Group 31 1125 CCA in mine. They just fit into the battery box's. Only trouble that I had was lifting them over the fenders, they are heavy. I'vs had them in for 3 years now and never had a slow start yet.

The OEM batteries were group 27 with 700 CCA each. Motorcraft has two batteries suitable for your truck.

BSD-27...750 CCA

BH-27A...725 CCA

You guys stating 1000 and up CCA's on your batteries need to look again. It ain't so.

444-4D I just checked your Tulsa weather it's 64.5 in Tulsa .. Well here it's -4 and snowing .. You can probably use 500 - 700 CCA batteries year around (maybe not even use the block heater) but I'll keep using my 1040CCA batteries

The original poster had an '87, I think they switched from 27 to 65 somewhere around in there, maybe someone knows exactly when.
