Hey Bobby! The 4,500-Watt Portable RV Generator item # 333-0005 uses a 12V sealed lead acid 7.5AH battery. It measures 5.95" x 2.55" x 3.82". We do not have these but you can find them pretty easily online. You'll just want to make sure you get the specific measurements because the battery mounts in its own compartment.
If you have any additional questions feel free to reach out to me directly in the comment box below and I will be happy to help you.
