Super Battery, display unusable, engraving is better than lasers

The battery looks great, fits perfectly and has enough power. Unfortunately, the setting is not useful since not read. Only with magnifying glass, so prefer not to use the marks, as it is blind. Therefore a point deduction. The battery can be adjusted by its markings it shows itself. Keep battery upright, hold the control wheel and use the shutter button as Notmarker. If you then rotate the battery and dial holds moves the shutter button to the upright axis. After a three-quarter turn is then final and it has reached the 4.8V. So you can remember, after a quarter of a turn there are about 3.7 V, for another quarter of approximately 4.2 V up to 4.8 V to the possible three-quarters Umdreheung. Exactly that is not, but relatively practical. Better looking than Lupe.
The display is lasered, that's just not as visible as engraved, which would probably not feasible in these small numbers. Also depending on the light one sees lasered writings times better or sometimes worse. Who has a lasered nameplate on the front door, knows how to sing a song about it.
