    worksheets section-Batteries question 5 re 150a/h rating.The revealed answer to Q5 although correct would not show the student had a sound knowledge of battery physics.

    A far better Answer to the purpose of the 150a/h. would be to say that it would discharge
    in 20 hours when supplying a current of 7.5 amps assuming standard 150A/H (c20) rating.
    and when supplying a higher current than c20 i.e 25 amp its capacity would be far lower than 150a/h.
