    Question Cold weather and Batteries ? What and where do I start the search ?

    I need to replace my 1990 Chevy C1500 and it's a 5.0 liter 305 ci engine. I couldn't find any information in the owners manual as a what battery that came with the truck new except that it was a "Freedom" type battery. I wanted to replace the current battery with one slightly stronger just to get pass the resistance in the wiring. Any where that I can do this ?

    @JTWard, the standard battery group for the GM fullsize trucks is a 34, or a 78 (sometimes called a 34/78). The group designation encompasses the physical sizes and the pos/neg terminal locations.

    There are a number of different amp hr and cold cranking sizes available for that grouping.

    Here is a start: http://www.batterystuff.com/kb/tools...oup-sizes.html

    If you have the stock battery cables you need a group 78 battery; you can use a combined group 34/78 battery that will also have top terminals but in general these tend to be of poorer quality. As to brand etc it all depends on what's available locally for you. I sometimes get batteries at the big-box retail stores, walmart, costco, menards, etc but they do not always have what I need -- none of them are really in the battery business and they just have a display that is refilled by a vendor who comes every week or so.

    The stock battery is more than sufficient especially for a 5.0.

    Well , I don't want to have top posts, they just double the chance of shorting out on my truck, Maybe a Delco battery with 700? CCA and a reserve of 95 ? Does that sound like my best choice, or do other manufactures make a side mount only battery as well ????

    almost every company makes side mounts. Autozone or any parts store will carry them. If you are buying one from a big parts store I recommend autozones battery, they are made by the same company that make diehard. Deka batteries and interstate are also good in my opinion. I would not buy another advanceautoparts battery.

ID:	58103 Yeah, Thank you. Interstate is a good battery, and they make a "Megatrom" Plus 75. They list it as being made to fit my Silverado and for a 305 V8 and it doesn't have any top posts. Cost is around $130.00 but any of the decent batteries are in the same ballpark ?
