My Temp guage rises all the way up after only a few min of driving or idling.

What is your question?

i have a 1994 Bmw 325i and have just had to change the battery in the car. National Tire and Battery sold me a battery that is not the exact battery that was in the car, but they assure me it would work just fine. my car does start better than ever but now my temp guage starts to rise almost immediately and im wondering if its something to do with the battery itself or if its something to do with the car resetting after having changed out the battery.
