IRIS Battery Charging Metrics Notifi cation:
Machines equipped with capability to report
battery charging data via IRIS are supplied with
a charger and set of batteries from the factory.
When a battery reaches its end of life and must
be replaced, Tennant highly recommends that
the same battery type be used to continue to
maximize the machines performance. In the event
a battery with a different amp hour (AH), type
(Flooded, AGM, Gel), or manufacturer is selected
for replacement please contact Tennant technical
service department for assistance in determining
the feasibility of the replacement batteries and
if so, selecting the correct charging profi le.
Availability of IRIS battery metric reporting is not
guaranteed with third party supplied batteries.
NOTE: If there is liquid in battery compartment,
drain battery compartment before installing
batteries. See BATTERY COMPARTMENT DRAIN
VALVE.
