Everything is great here. Batteries are recent production and long shelf life.
Each 9-volt battery in my delivery einzelnd packed with film and tear-open the latch of 10 pieces.
The Volt pays has the usual reserve and is measured at 9.63 volts. This is evidence of the highest quality!
Can not see any weaknesses or lack of stamina for use mainly in various smoke detectors etc.. The life I would even estimate at about 10-12 months, at the two expensive devices to about 24 months, but these mooring less on the battery as the power consumption of the smoke detector.
Except for the two more significant are mostly very inexpensive smoke detector, which usually do not even contain partly the VDS characters.
The performance exactly this to other alkaline batteries could only be unequivocally determined and highlighted, for example if several identical devices in continuous operation (as just the smoke detectors) a Varta Idustrial and the comparison batteries were used in the other.
In older remote controls or calculators with LED display, which were previously still operate with 9 volt block, the life many times many years amounted depending on the degree of use. Sometimes my part was the battery even more exchanged for prevention of other problems on the device than by really nachgelassende battery power.
Since I had to complain about any negative experiences or even leaking batteries in everyday life, strong buy recommendation on my part.
Thank you that you have read this far in the hope I could contribute something to your purchasing decision or general informational content.
