My riding mower came with a 165 cold crank amp battery. I was wondering if I could get away with a 145 cold crank amp battery?

Probably can during the summer months. Why do you want to do this, already have a 145 to spare or what? They are almost the same price new.

Thanks for your reply. I can get a 145 for 19.99. A 165 & up goes for about 28.00 and up. I'm on social security disability so every little bit helps.

You should be OK but don't use 30w oil when it gets cooler I'm the fall.

You'd better choose an appropriate one.
