Its got a reserve capacity of 120, and a 20 amp hour rate:55. I'm by no means a battery expert. Hopefully it will work out fine.

If you have the stock battery box like mine, they probably won't fit. You may need to replace that as well. Mine will barely fit 2 group 27's and it's a tight squeeze. I've had those Duracell batteries in my boat. They're good batteries. I have one group 31 for cranking and 1 group 34 for the trolling motor.

I use 6V batteries whose capacity is 180 to 205 amp hours.

Looks like the width and depth are the same, the Group 24 is actually an inch or so taller than the Group 34.

Carl, how many of the 6 volts do you run?

I have 6 installed just so I don't have to worry about usage all that much. I basically run the entertainment center (TV, Stereo, DirecTV, computers) and lights (all LED) off the inverter.

Carl was there anything you had to change with the factory inverter to charge the 6 volts?

No the 6Vs are wired in series to so they (each set) are 12V to the converter.

What you want to look for is the 20 hour amp rating. Those Duracel batteries are 55 amp batteries rated at the 20 hour rating. Wired in parallel you will have 110 amp hours of available power. Depending on your needs, this may be fine but if you boondock you are going to be lacking in available power.
