1975 Cessna 172M. Wing nuts on the posts make the battery box lid tilted a bit. Nothing dangerous, but the next time I pop the top cowling Im going to change the wing nuts to the brass bolts that came with the battery. That should allow the box lid to fully close.

Prices are high for what size it is,but that’s aviation.It works so far. Came in a gigantic box I thought I was getting a washing machine.

I recently ordered 2 of these batteries as replacements for 2 7025-20 batteries because they had dropped below 60 percent capacity and are 6 years old. I purchased theses batteries because of the reliability of the last set.
