A friend has a disabled buggy for short distance trips. It is supposed
to do 25 to 30 miles on fully charged batteries. Last week it stopped
dead after about 10 miles. It was retrieved by the insurance company
and taken to the workshop for repair. A fuse had blown and so both
batteries needed replacing. Can anyone explain how a fuse blowing
results in the batteries needing to be replaced. They are sealed lead
acid batteries.

Any ideas?

My guess is that it's the other way around. The bad batteries
(voltage lower than spec due to bad cells) caused the electronic
controller to draw too much current in an attempt to maintain speed.
That's just a guess, though. It is hard disagnose something with no
information. It is also possible they replace the batteries whenever
they do any other repair to avoid another trip to the shop as the
batetries reach end-of-life.

The batteries were brand new about two months old!

I should have typed "two months ago!"
