Spring launch is here and considering replacing my 5 year old batteries. Currently have dual interstate 24M-XHD batteries with the ACR that came standard with my 2015 R5. Thinking of replacing both with new AGM batteries, Interstate 24M-AGM. Are there any concerns with this option? Also does anyone use or have thoughts on applying Permatex Dielectric Grease on new battery terminals? Thank you.

Lots of people have used various AGM batteries, and they perform well - see here for another thread on battery choices - viewtopic.php?t=9170

I haven't used dielectric grease on battery terminals, but don't see much harm if you have corrosion issues. I do have a battery terminal brush, and clamp the battery terminals on snugly and have never had issues.

When using dielectric grease, first assemble and tighten the connection dry (metal to metal). Then apply a light coat over the connection.

Thank you all!

This post is a little late. I switched to AGM 31’s replacing my wet batteries. Later, I got chewed out by my mechanic as my 7.4 liter’s alternator produces a max 14.2 volts. The voltage range for the AGM’s is between 14.4 and 14.7 volts. The AGM’s are designated marine use btw. He said they will never be fully charged and would last 5 years or so. I sent them back and bought two marine 27 model batteries from Costco. For half the price.
