Thank you, I'll stick with this one.

In questions like that first you have to calculate stall speed with bank angle 0.
And then you can calculate stall speed for 45 degrees bank angle.
As in 15 degrees stall speed increase is very small, regular stall speed will be around 59kt. At 45 degrees stall speed factor is 1.19 so stall speed will be 59 * 1.19 what equals around 70kt.
Here is good article with formulas what explains everything: http://www.experimentalaircraft.info/flight-planning/aircraft-stall-speed-1.php

Self correction: there's no such think such as replaceable lead acid cell.(study a/c lead acid battery in detail u'll know). Hence "cell is defective" has to be right answer in this case.
