I was wondering if i can disconnect the battery N-50SB3 by cutting the leads to prevent leakage in the future. I own a NMS-8280.
Will the MSX still function then?
Or is it better to replace it with a new one?
Could not find much about this on the world wide web. So that's why i'm asking here.

Regards,
Patrick

It will function, but it will always forget the time and date (and some other settings). Not critical, but can be annoying.

i think its better to replace the battery because of the clockchip
the chip remembers the settings from your system, your prompt the time and more
I replaced the battery because my color setting and prompt are changed and I don't like the klick sound when you type in a letter, you can turn it off in basic and with the set screen command it writes the to the clock chip

so I think replace the battery, but if you don't care about that you can cut it away the computer still works

Always nice if these basic functions still work. Are there any replacements on the marked today that can be used. And have a very low or no risk for destroying the motherboard when disaster strikes?

You can modify it to not charge the battery and use a PC lithium cell in a battery holder, such as CR2032. It doesn't leak after it runs empty. Very stable.

I replaced the NiCd battery in my Sony HB-F700, see reply #8 and #9 of this thread

There is a correct replacment for the Sanyo N-50SB3
The Powercell 5051 3,6V 120 mAh NiMH 11 x 50,5 mm with wires.
The old Sanyo N-50SB3 don't leak because they are sealt.
So, there is no reason to remove the Sanyo N-50SB3 when you are afraid of leaking.
Unless you are going to replace it by a new one.

I just made a picture of mine MSX and the battery i'm talking about. So is this the sealed battery that you were talking about Zilogger?

Yes.
Sealed on each end of the battery.
The batteries in a Sony HB-500, HB 700 could be leaking.
I'll found many HB-700 with leaking batteries.
I replace them with non-leaking ones.

I cut it out and I never missed it because I let my megaflashromscc+sd set the right settings during boot... Off with them nasty batteries.

Got two more for the naughty corner
