The battery cover closes easy with still some room to spare...
I don't know about the external dimensions of your battery brands there...but the one I had 7 mah has the same base dimensions as the available 9 mah... the 9mah only half an inch higher...
This is my new battery, as you can see on it's top part it says YTX9-BS ... it's compatible with the Yuasa YTX9-BS below... but I think the Yuasa is only 8 mah...
If you can see the difference in height of the MF7A-B and MF9-B below is very small...
Kept on wondering if the 9mah is really the required battery for my scoot and the dealer just changed it with a 7mah...
Guys, let's compare batteries... can you post the brand and model number of your batteries? I'm curious...
