To remove the battery on a es400b you have to remove 2 screws behind the front wheel. behind the front wheel are 4 screws that form a square. when you remove the 2 screws on the bottom, the lock for the battery is loose and you can pull the battery out.
People you don't need to remove any screws or a 150€ device. All you need is something strong for prying. I first tried a flat head screwdriver but takes too long and the tip broke but it could work if it's all you have but wear safety glasses so that a piece of the screwdriver doesn't fly into your eye. I then used a cold chisel which only took 10 seconds to get the battery out. But be careful the battery hit me hard on my knee but thankfully I'm fine.
EDIT: I was very wrong first battery was easy probably from prying with a screwdriver but second one very hard with only chisel, I even accidentally hit my tooth with the chisel but miraculously my tooth didn't break lol. Tried to remove the screws behind the front wheel but two of them are in a very hard to reach place even with my micro 1/4 ratchet. I was able to remove the two bottom screws but battery isn't coming out.
