Float mode versus Maintain mode:
In float mode the charger does not shut off completely, but
supplies a very small current to the charged batteries to hold them
in full charge condition. They will not be allowed to discharge at
all. Using this setting, batteries may be left unattended for weeks at
a time. However, if weeks could turn into months then the
maintain mode would be more suitable. On wet cell batteries, there
will be some water usage especially in hot weather using float
mode.
In Maintain mode the charger will shut off, but the batteries will be
maintained by way of the charger checking the batteries
periodically using a combination of time, and minimum voltage.
Use this setting for long periods of inactivity, or if it is just
preferred over float mode.
Sometimes selecting the wrong switch setting will result in under
or over charged batteries. Other times there is no, or little effect.
The worst maladjusted switch setting would be using the wet cell
setting on most sealed batteries, which will harm them fairly
quickly due to overcharging. On the other hand, many wet cell
deep cycle batteries are fine using the sealed AGM setting.
NOTE: The rest of the instructions apply to all chargers
regardless of date code
A note on particular battery brands.
US Battery
,
Full River, Odyssey, Northstar
are brands that
benefit from longer charge cycles. When using these batteries, the
#1 switch should be ON, which lengthens the cycle.
When re-assembling charger, replace paper insulator and
reassemble, making sure not to pinch any wires in the covers.
