CHARGING BATTERIES
The charging instructions in this manual are intended
for the battery charger supplied with your machine.
The use of other battery chargers that are not supplied
and approved by Tennant are prohibited.
If your machine is equipped with an off-board bat-
tery charger refer to the charger’s owners manual for
operating instructions. Contact distributor or Tennant
for battery charger recommendations if machine is not
equipped with charger.
FOR SAFETY: The use of incompatible battery
chargers may damage battery packs and potentially
cause a fire hazard.
IMPORTANT NOTICE:
The battery charger is set to
charge the battery type supplied with your machine. If
you choose to change to a different battery type or ca-
pacity (i.e. flooded (wet) lead-acid, maintenance-free,
sealed, AGM batteries, etc.), the charger’s charging
profile must be changed to prevent battery damage.
See BATTERY CHARGER SETTINGS.
