As far as i know, only the hardware manufacturers and major distributors 
would have reliability data for a large sample of devices, and I'm sure 
that information is confidential. In short, we in the general public 
don't know anything about reliability apart from anecdotal reports on 
mailing lists or other fora.

According to an online presentation about the Monarch from Quantum RLV 
in Australia, there is a tool that can be used (presumably at service 
facilities) to replace cells individually. In some countries, a hardware 
maintenance contract can be purchased that takes effect once the 
warranty has expired. For such a valuable product, this may well be 
worth the investment.

Battery life of the Monarch is reputedly excellent, up to a full day of use.

Regarding devices from other manufacturers in the same general category, 
I think it is reasonable to expect each cell technology to have its own 
reliability characteristics. I also agree that hardware reliability is 
very important, especially in view of the prices of refreshable braille 
cells. Total cost of ownership is the relevant measure to consider. 
While the up-front purchase price matters, the total cost of ownership, 
including maintenance and repair costs, gives an estimate of your entire 
investment over the life of a device.
