In my opinion, even if you don't use the chairs, it doesn't mean that the batteries won't run out. I highly doubt that others will last the same for me.

My first set of MK batteries lasted me over 20 years.

They may have "lasted" 20 years. They were end of useful service life long long before that!
They are, according to the manufacturer at end of useful life, and down in capacity by 20% after 10 years float life when used as a backup battery. Thats as long as they can last. In float use. And down by 20% would be very noticible to many users inc me.
So no way on earth that a 20 year old battery - even if charged CORRECTLY which they seldom are, certainly not with a mobility charger - is anything other than a doorstop for at least 15 of those years.

Out of curiosity, how many kilometers can you do on a normal day?
Are you still using gel batteries? How many charging cycles will the batteries last in optimal conditions, charging them correctly for 300 cycles according to the graph?
I would encourage you to post a post telling what is the correct way to charge the batteries and what to use to do so.
