Battery is not included.
Only use the Voltage Transformation Type with silver oxide batteries. Alkaline batteries give poor results.
Due to unforeseen restrictions on different models, testing by the use is required prior to actual use.
Due to erosion or a weak spring, the contact of the battery may be unstable.
In case a camera is broken, it may not work even if you use a suitable adapter and battery.
The voltage transforming type adapter cannot handle a large current, therefore you cannot use this type of adapter for products which require a large current.
In order to measuer the voltage transform adapter using a digital tester, put a 10Kohm resistance between the measurement terminals.
Our test results are based on a measurement at ordinary temperatures, under ordinary photographic conditions.
