Installing the battery a little fiddly at Seo5.
Virtually undetectable +/- marking on the battery housing in low light: embossed characters in black, on a black housing ...
Have the battery is not stressed, more evaluation, and the fifth star there, when I have more experience with it.
My hope is, the battery will last at least several hours and use phase, can then be charged, so I always have a fully charged battery from the start there again.
With AAA batteries, it has worked for me in the Seo5 previously almost did not work, although expressly permitted by the manufacturer: the lamp went after a short use, with white LED full strength, in the mode of "reloading" over and has permanently with the red LED blinking.
With batteries it kept much longer, but after a few hours use also here the flashing annoyed, especially with the single red night lighting light when blinking is actually turned off the flashing rhythm - because you get almost stumble.
