NSS eForce - Battery Replacement Notes

Operating the Battery Charger
The battery charger is fully automatic. Simply plug
the charger into a suitable wall outlet, and the
charger will charge the batteries. The amp meter on
the right side will start with high amp output and drop
to 0 when 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.
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.
 Unplug the charger from the wall outlet, then plug it
back in.
The charger will run 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. 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 Replacement Notes
 Entire Pack.
oIt is always recommended to replace all batteries
in the pack at the same time.
 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.
o
If you wish to only replace some of the batteries
in 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. (s.g. = 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 3 hrs.
run time, only run it for 2 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.
Battery Do’s and Don’ts:
a. You do not have to fully discharge the batteries
before charging. They do not have a “memory”.
b. Plug the charger in anytime the machine is not in
use.
c. 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.
d. NEVER refill the batteries with well or tap water
(flooded cell batteries).
e. NEVER overfill the batteries (flooded cell
batteries).
f. NEVER let the batteries sit discharged overnight
(or between shifts).
g. ALWAYS check the electrolyte level about every 3
or 4 charge/discharge cycles BEFORE
CHARGING.
h. ALWAYS refill the batteries with distilled water (if
needed) AFTER CHARGING.
i. ALWAYS fully recharge the batteries after use.
j. ALWAYS equalize the batteries (Flooded only)
every 30 days.
k. NEVER OVER DISCHARGE!
l. NEVER charge GEL batteries.
If contact with battery acid occurs:
 Skin – Rinse with cold water for 15 minutes.
 Eyes – Flush with cold water for 15 minutes.
 Internal – Drink lots of water or milk. Seek medical
attention immediately.
