Nah! That battery is definitely not the most difficult to get out. Have you ever tried to remove the battery on a Honda Metropolitan? WAY harder to do. Definitely need that handle or it's just not coming out. Even the battery in my CTX1300 was WAY harder to get out. The AK 550 battery was easy by comparison. I didn't need any handle and was able to remove it easily. I also even figured out the fuse block attachment. Slip a very small flat blade screw driver under the tab and it slips right off. I removed the battery a few times already just to check things and also when adding some electrical farkles that are now laying on top the battery cover. The tools that came with my AK plus one more tool that I added to the kit are all I need to get to the battery and fuse block on the road. I added one or two more tools and can almost completely tear down the bike to the bare frame in the field. This is IMO one of the easiest bikes to work on that still has a full fairing. And the fairing panels are the easiest to work with, remove and install, of all the full fairing bikes I've owned. It's just a matter of learning how to work with them.
To the OEM tool kit simply add this tool to make it easy to get the top front totally exposed.
https://a.co/d/4IK6SNxI've used this tool for many things on my AK including removing the storage box when installing the hitch that I made.
The tool kit already includes, or should, the Allen wrenches needed. If not add a small size set of those from 3mm up to 6mm.
I did replace the cheap screw driver with a better one but that was a tool for tool swap.
