Removable or not removable battery, that is the question !

Hello to all the MSX faithful.

I would like to know, among all the MSX 2 and upper models, which ones have an easily removable (and replaceable by a normal user) RTC battery (I have read it's possible on some models) and which ones have it soldered on the mother board (necessitating specialized, surgeon work !).

Does such a listing exist ? If yes, where ? If not, we could make one there !

Avoid alkaline batteries because they leak one day or another.

The AX350 and AX370 both take AA batteries for RTC. True the AA batteries leak, but for both of those models, the battery compartment is below the motherboard, so even if they leak, they will drip down on the table instead of any electronics.

Interestingly, even the AX170 (Sanyo MPC2) has a battery holder in its plastic mold. Except I never saw it used or exposed with a removable cover.
