Hi,

I would like to ask you what should be the best brand and specs for a battery for a 1991 Cadillac Brougham D'Elegance?

It seems that somebody stole my car's battery, I need to buy one as soon as possible so I can open the trunk and start the engine.

I need to know the Brand of the battery and the power specs.

Thanks

Of course it will be ACDELCO :)

Don't obsess over all the specs. Most parts stores will list minimum CCA, and of course group size. Stick with a name brand, AC Delco, Bosch... Several members are really happy with Wal-Marts MAXX batteries.

I just saw the following AC Delco compatible batteries with my car:

BATTERY ASM *CCA 800)(DUA

6 Year Dual Terminal Battery
4DR ; Dual terminal-Battery CCA rating 800 ; 78 BCI ; 0730 CCA

BATTERY ASM *CCA 735)(DUA
Part Number: ACD3478
Product Notes:

What is the difference between these 3 I really don't know.

The top 2 are dual terminal (top and side), which you don't need. Top one is 800CCA, second is 735CCA. The third one is side terminal, 800CCA. Different warranties too.

So I should search the local market for the "third" option.
800CCA should be good for my 5.0 liter engine with the AC and other electric features...

Any one of those batteries will work fine. That dual terminal 6 year warranty sounds best to me. Dual terminal is cool in case you have to jump it, test it or hookup accessories.

It really doesn't matter what one you get, go for price. If you have cold winters and use the car go for one with more power.

The only difference between the side post battery and one that has both is the one with both is universal to work with more cars. Side post pretty much limits you to GM.

As others have said, any group 78 will get the job done. A smaller group 75 will as well.

I got a Optima red top battery. Part# RED78. 800 cca and 1000 ca. It's not the dual post one, but I don't want something to accidentally hit the top posts and short something out. Even though it comes with little covers, I am hesitant on them.

Make sure you keep it charged. Optimas really don't like getting discharged.
