The rechargeable battery is not included ... it's a little cheapskate problem and asked me a few moments. The label on the battery slot indicates mandatory NI-MH, 1.2 V and 180 mA ...! Found !! Fortunately, doc (leaflet) corrects: 1800 mA minimum ... and that's current, OUF! I always have a charged ahead. For the rest, good first impression, especially for grip.
