Supplied batteries are an impertinence!

But how can you mitliefern only those absolutely substandard batteries?
Then rather no mitliefern!

20 years ago there were already more often before the batteries run out pretty fast, but actually there is no longer a problem, even with low batteries for a long time.

But the batteries of Lupe did not even China-quality, and are completely expired after a few weeks.
This then from the magnifying glass handle to remove (is a cylinder with one-sided opening), is extremely difficult because the batteries of course, stick, and the material of the handle starts to corrode inside. When pulling out the batteries, these are also torn. Took me a lot of work cost the handle again to make them suitable for new batteries (sand out interior, etc.).

So, at best dispose of the batteries and use the same "normal" battery / batteries.
