PROPER CARE AND USE OF BATTERIES:
CAUTION:
Always wear protective eye shields and clothing when working with batteries. Batteries
contain acids which can cause bodily harm. Do not put wrenches or other metal objects
across the battery terminal or battery top. Arcing or explosion of the battery can result. Do
not wear jewelry when working around batteries. Arcing can cause severe burns.
New batteries will not deliver their full performance until after several cycles.
The tops of the batteries and battery hold downs must be kept clean and dry at all times to prevent excessive self
discharge and flow of current between the battery post and frame.
Maintain the proper electrolyte level by adding water when necessary. Never allow the electrolyte level to fall
below the top of the battery plates. Electrolyte levels fall during discharge and rise during charging. Therefore,
to prevent the overflow of electrolyte when charging, add water ONLY AFTER the batteries have been fully
charged DO NOT OVERFILL. Old batteries require more frequent additions of water than do new batteries.
Do not over discharge the batteries. Excessive discharge can cause polarity reversal of individual cells resulting
in complete battery failure.
USING THE DISCHARGER:
Testing should be done in a cool, clean, dry, and well ventilated environment. Position the discharger on stone,
brick, concrete or grounded metal.
DANGER: To reduce the risk of fire, do not use the discharger near flammable materials or vapors.
The purpose of using a discharge unit on battery sets is to determine battery capacity, and to find defective cells
or batteries in the set.
Battery energy is measured in minutes obtained upon discharging a fully charged battery set. This standard is
used by all major battery manufactures’ of deep cycle marine, golf car, or floor scrubber type batteries. The
discharger places a 25, 56 or 75 amp resistive load until a shut-off voltage of 1.75 volts per cell is reached. If
the shut off voltage is not reached in a maximum of 400 minutes, the discharger will time out and shut off.
1.
Before the test, fully charge the battery pack. It is important that all the batteries in the pack are fairly even.
By voltage, monitor each battery towards the end of the charge cycle. Any battery(s) that are 3/4 – 1 volt lower
than the rest of the pack should be charged individually.
2.
To start the test, observe polarity, red+ black – , and connect the clamps to the pack.
IMPORTANT: Make
sure the posts are clean, and the clamps are tight.
Bad connections will cause the unit to fault, and the
cycle to be interrupted with a “system failure” message.
3.
The solenoid will close, and the system voltage will be displayed, along with the rate of discharge. (S
ee
reprogramming section to change
). Press the START/STOP/PAUSE button. The cycle will start, and the
running time and battery volts will be displayed.
4.
The cycle may be interrupted by pressing the button, and restarted by pressing it again. If it is not pressed
again, the tester will shut off. The fan will continue to run for about 3 minutes after shut down.
DANGER: N
ever move the clamps while the red LED is lit and the tester is under load, the resulting
arcing can cause injury and damage to personnel and equipment.
