note the following:
The number of tests you can perform with recharged
batteries is considerably less than with ordinary batteries.
To be ready to test at any time, you need to keep two
rechargeable batteries in reserve which you can charge while
the first pair are in the meter.
Recharged batteries lose their charge during storage.
When the battery symbol first appears, you can perform
significantly fewer than 50 further tests. With old and
exhausted rechargeable batteries you may not be able to
perform even one more test.
