900 CCA battery for Charger?

Have any of you put the H8 batteries from Walmart into your hemi. I want the higher CCA, cuz it gets cold as F here and I have a system installed so. Yea. The 730 is IGHT but I'm sure the extra 170 wouldn't hurt. I swapped the battery on my old Honda a while back with a huge battery and that **** started so much stronger. Was ridiculous. Let me know guys ty

There are NO batteries in a Hemi, the battery is located in the vehicle where the Hemi is installed and that is a wide range of dodge vehicles. The limiting factor is the size of the battery box (hold down configuration). You can buy same battery group sizes in various CCAs as ccas are related to the plate density internally. Basically yes it can be done and it doesn't hurt anything.
