manufactured as a pack from six individual cells. This type of battery is not so

susceptible to the top-up charging 'memory effects' as nickel cadmium batteries.
However as a best practice it is suggested to cycle the batteries charge as much as
possible and then fully charge the batteries. Although small top-up charges can be used
to complete a day's readings, if necessary, they are NOT suggested.
Note: To charge, the analyzer must be switched OFF before
attaching the charger. Switching the analyzer on or off
during charging will cancel the current charge. The
analyzer should be left OFF during the charging cycle.
