q
Minimum battery life (as per Nf EN 61557-2)
Test voltage
Nominal load
Nbr. of 5s measurements on
nominal load
(with 25s pauses between
measurements)
q
Mean battery life
Assuming a 1-minute DAR measurement 10 times a day and a 10-minute PI measurement 5 times a
day, the battery life will be approximately 15 working days, or 3 weeks.
q
Charging time
6 hours to recover 100% capacity (10 hours if the battery is completely run down)
0.5 hours to recover 10% capacity (battery life approximately 2 days)
Remark: it is possible to charge the batteries while making insulation measurements, provided that the
values measured are greater than 20 MΩ. In that case, the charging time is longer than 6 hours, and
depends on the frequency of the measurements made.
