Also, there is the perfect place to put a screw in the battery tray (looks like for some reason the plastic is molded for one). I put a screw in the hole with a small plastic bushing around and it keeps the battery exactly where it should be (perfectly aligned on the right side of the tray.
A big bonus is the battery is much lighter than the old school batteries from the 80s. The car was already light.... but she is a happy car now and rips pretty good!
