I hope the battery's not dead! When I tried to take it out last year
(when I first started this job) it would NOT come out of the mower body,
following the manual's instructions. I may have to take the mower apart
to get the battery out.

I will have another go at charging next time I'm across. And No Dave,
I didn't charge it last thing last autumn, mainly because (having
successfully charged it when I took this job on last year) it always
started first time thereafter (it takes about 90 minutes to cut the
grass).

If it is a sealed lead acid battery (SLA) it is almost certainly
defunct, they really dislike being left discharged for any length of
time.

Charge it up. Leave it disconnected for 48 hours then check the voltage.
You'll soon see if a cell has gone down.
