The cycles don't matter unless you are trying to run a clock. Just ensure that the transformer you get has a 220vac input and a 110vac output. The battery charger has an additional transformer to take 110vac to whatever voltage is required.
However, check your battery charger first. Many of them have dual input capabilities. If so, it will be written on the battery charger similar to: "110vac-240vac input."
This not technically correct. Transformers require a heavier duty core structure to sustain function in a 50hz environment without oversaturation of the core and/or overheating of the coils as compared to a 60hz system. Most wound transformers or equivalent solid state voltage converters today are built to 50hz standards and automatically are capable of 60hz operation. The opposite is not true. Thus a 50/60hz spec transformer is approved/built for 50hz operation whereas an old 60hz only specified unit has the potential for a short, fiery life in a 50hz environment.
