Operating the Battery Charger
CAUTION: DIFFERENT BATTERY TYPES HAVE
DIFFERENT CHARGING REQUIREMENTS. FAILURE
TO PROPERLY IDENTIFY YOUR BATTERY TYPE
AND SET THE CHARGER ACCORDINGLY WILL
RESULT IN BATTERY DAMAGE, AND VOID THE
WARRANTY.
The battery charger is fully automatic. Simply plug the
charger into a suitable wall outlet, and the charger will
charge the batteries. The green 100% LED will be
continuously illuminated when the charge cycle is
complete.
A bubbling, or boiling sound coming from the batteries
during the last few hours of the charge is normal. The
batteries may be warm, but not too hot to touch.
The charger will maintain the proper battery voltage
as long as it is plugged in (maintenance mode).
Equalizing the batteries (Flooded only)
The batteries should be equalized once every 30 days
for maximum battery runtime and life.
To equalize the batteries:
 Plug in the charger, and fully charge the batteries
(until the green 100% LED is on continuously).
 Unplug the charger from the wall outlet, then plug it
back in.
 The charger will run for 2hrs, holding the batteries at
a constant voltage, and equalizing each cell.
Opportunity Charging
Opportunity charging is charging the batteries when an
opportunity presents itself, such as during breaks, and
is done in addition to a full charge cycle.
Opportunity charging is recommended, as this extra
charging time will help raise the operating voltage of the
batteries, and will help ensure maximum runtime and
cycle life.
See Operating Battery Charger Instructions or
Monthly Maintenance for equalizing your batteries
especially if you have been opportunity charging
your machine.
Battery Do's and Don'ts
 You do not have to fully discharge the batteries before
charging. They do not have a "memory".
 Plug the charger in anytime the machine is not in use.
 NEVER let the electrolyte level fall below the tops of
the plates (flooded cell batteries). This will damage
your batteries almost immediately, and void the
battery warranty. They can tell if this happened.
 NEVER refill the batteries with well or tap water
(flooded cell batteries).
 NEVER overfill the batteries (flooded cell batteries).
:
 NEVER let the batteries sit discharged overnight (or
between shifts).
 ALWAYS check the electrolyte level about every 3 or
4 charge/discharge cycles BEFORE CHARGING.
 ALWAYS refill the batteries with distilled water (if
needed) AFTER CHARGING.
 ALWAYS fully recharge the batteries after use (until
the green LED comes on).
 ALWAYS equalize the batteries (Flooded only)
every 30 days.
 NEVER OVER DISCHARGE!
 NEVER charge GEL batteries with the charger set to
FLOODED/AGM.
 NEVER charge FLOODED/AGM batteries with the
charger set to GEL. EXCEPTION-CROWN AND
TROJAN AGM'S TO BE CHARGED WITH GEL
SETTING.
Battery Replacement Notes
 Entire Pack.
It is always recommended to replace all batteries in
o
the pack at the same time.
 One or more batteries out of the pack. This is not
recommended. Replacing just one or two batteries
out of the pack can lead to the following:

Overcharging the new, or the remaining
original, batteries.

Undercharging the new or remaining original,
batteries.

Over discharging either the new or the
remaining original batteries.
If you wish to only replace some of the batteries in
o
the pack, follow these steps for best results:

Replacement batteries must always be of the
same battery manufacturer, model, and amp-
hour rating as the remaining batteries in the
pack.

Never mix batteries from different
manufacturers in the same pack.

Fully charge both the new battery, and the
remaining original batteries. (specific gravity =
1.265 minimum, use a hydrometer)

Use a replacement battery that is close to the
same age as the remaining original ones.

Do not run the machine as long for about 20
cycles. For example, if you used to get 4 hrs
runtime, only run it for 2.5 hrs, and then charge
the batteries completely.

Opportunity charge whenever possible.

Equalize after 30 days (Flooded only).
 The above steps will provide the best
opportunity for the new battery(s) to join the
pack.
