I'd have to guess that the "analyst" label of "ah" is probably "ampere-
hour". The correct symbol would be:
A·h
or
A.h
or
A h
(I'll used the raised dot form here. See PS below.)
Better yet, A·h can be converted into coulombs (C), a unit of amount
of electric charge. A coulomb is equal to one ampere-second:
1 C = 1 A·s
Since you have it in ampere-hours you'd convert by replacing the hours
by "3600 s" and get
1 A·h = 1 A x (3600 s) = 3600 A·s = 3600 C
which could also be written in kilocoulombs, as
3.6 kC
The SI unit of time is the second but electric power people keep
insisting on using hours instead. They claim it is easier to use hours
rather than seconds because using second makes the numbers
inconveniently large. Of course that's false because they can use kJ,
kC, MJ, etc.

P.S.
In most of the above, I have used the raised dot to indicate
multiplication of two units; e.g. amperes (A) times seconds (s)
yielding "ampere-seconds" with the symbol "A·s" (with a raised dot
between the "A" and the "s"). If some of your computers do not
recognize the raised dot that my computer is sending, then some of the
symbols above may not be appearing in the correct format above.
