Battery question

I have a question about batteries. I own a 1995 Full size Chevrolet Sport Van. Late Spring of last year I figured it was due for a new battery. Wife drove it into town where she worked to get some brake work done on it, while there she mentioned that I was thinking about replacing the battery....... the guy offered the same price as what I had looked at while at Walmart and he would install it and dispose of the old one ..... so I gave him the "okay" to replace it.
Never had a problem 'til the cold weather set in up here. Now it almost never holds a charge. If I want to drive it, I have to jump it with wife's Dodge Caravan.
We have since moved several hours drive away from this shop
After it did this a few times I drove the several hours to his shop (we were going that way anyways to see family) and he supposedly replaced the battery with a similiar one figuring the 1st one was bad (I should of marked the old one somehow).
That solution did NOT work. If it sits more then a few days in our cold temps, it will not start back up again without a jump.
I called him and explained what's happening. His response was "Well you must have a short or something in your wiring, or something is wrongly connected drawing energy from the battery".
I don't agree. Since she took it into the shop for me, I'm the only one who has driven it, have had no passengers to mess with anything, thus nothing has changed. The stupid battery just won't hold a charge.
I've owned this van for three winters up here and never had this much problem!!
So I'm thinking that he put in a battery that is to small. My question is..... I don't remember what size the old battery is and I don't have an owners manual for my van.
I've done some reading on google and know that I need to look at the CCA (cold crank amps) but I haven't been able to figure out WHICH size I need.
Can anyone help me out? Your advice is much appreciated.

I'm thinking that I can just buy the correct battery I need for my full size van in this cold weather, and save the current battery for when my wife's mini-van needs a new one?? Does this sound right?
Thank you again for your assistance.

You might have also have a problem with your charging system. Do you have a vom meter? If not go to Advance autoparts or auto zone and have them test your battery and charging system.

Make sure all interior lights are off including glove box, underhood light all it takes is one little switch to go bad.

Pull the - terminal off the battery and then touch it back on it while looking for sparks. If there is a short you should see some. Also try leaving the terminal disconnected while the van sits. If it starts as normal then you do have a short.

For a few $ you can get a hydrometer from the auto parts store. It looks like a turkey baster and you draw some fluid from each cell in the battery and read the level on the float. If one cell is lower than the others that cell may have a short.

I agree with testing with a hydrometer, all cells should be within about 25 of each other if the battery is good. If the battery has been discharged and sat out in cold temperatures it might have frozen and isn't any good any more.

Take a volt meter and check the battery, then start the van and check it again, should get a higher reading if the charging system is working.
