already started a battery thread but has been kind of hijacked....just simply need to know which optima batteries work with my vehicle, its an 87 subaru gl wagon, carbed, ea82 no ac. It shows on their website the redtops that work but cant find a guide anywhere on the yellowtops. Need to know asap so I can get one on its way.

well i'd say measure your current battery length, width, height, then but the biggest one that will fit

edit: sorry stated the obviouse

Hi BlindSight,

 

Keep in mind there are at least two sizes of batteries for these cars. A Car with AC takes a physically bigger and heavier battery. If you don't need the big one pass on it. Less weight and expense is a good thing.

but a bigger battery = more power. depends on what you want. Honestly I'd go with as big a battery as will fit as long as it isnt TOO heavy.

i have never really been too worried about having the "right" battery for my car, as long as its big enough and physically fits in the spot. I guess if you are ordering it online its one thing, but the series IDs should be the same from one model of battery to the next... its sorta like tires, the way they are numbered... but I can't give you any more detail than that, my knowledge is a bit fuzzy

generally they have a 4 digit code the first two for example 58-84 58 is the battery size, and 84 is the warrenty period in months,

Dude, First off unless you are running tons of lights and additional accessories ie, winch, speakers, you dont need a yellow top. They are for deep cycle only it wont give you any more performance then a red top. I am in the military and we only use red tops even in some of the biggest vehicles. Yellow is more expensive and heavier to do the same job as a smaller red top.

 

Red not Yellow

I just swapped out a giant battery for my little trusty one to fit the sube. the little one cranks the little starter on the little engine strangely faster (anyone explain?), like one big happy little family all working together.

well I do have a pretty huge system...and do have 4 offroad lights...thats why I opted for the optima yellowtop....but don't have ac.

The bigger alternator hack vs the battery gets my vote for several reasons. I think of the battery in a sube just for the starter. Battery too big does stuff- alternator big has engine fans, car moving, engine running, kills off some of the invisible. I haven't had good luck,large battery. If it fits in the oem battery holder, it is big enough. I would like to try out the bigger alternator route for large amps, lights, etc. I am not sure how big you are intending, but I have learned the hard way (it all starts with the starter....) that there is an extreme battery if it is too big.

if your gonna be running the sound system with the car off you want a yellow top as the red top won't last as long before you will be unable to start your car
