IMPORTANT SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS – This manual contains
important safety and operating instructions for battery charger Model 965.
2. Before using this battery charger, read all instructions and cautionary markings on the battery
charger, battery, and product using battery.
3. CAUTION — To reduce risk of injury, charge only Isco type rechargeable batteries.
Other types of batteries may burst, causing personal injury and damage.
4. The Model 965 is for INDOOR USE ONLY. Do not expose the battery charger to rain or
snow.
5. Use of attachments or appliances with this unit that are not sold or recommended by Isco may
result in the risk of fire, electric shock, or personal injury.
6. To reduce the risk of damage to the Model 965 cord and plug, always grasp the plug when dis-
connecting the unit, rather than pulling on the cord.
7. When the Model 965 is in use, make sure the cord is located so it will not be crushed, stepped
on, tripped over, or otherwise subjected to damage or stress.
8. Do not use an extension cord with the Model 965 charger unless it is absolutely necessary. Use
of an improper extension cord could result in the risk of fire or electric shock. If you must use an
extension cord, please make sure of the following:
a. The pins on the extension cord plugs are the same size, number, and shape as those of the
plug on the charger.
b. The extension cord is properly wired and is in good mechanical and electrical condition (no
frayed wires or exposed connections, and firm retention of the plug when inserted).
c. The wire size of the extension cord is adequate for the AC ampere rating of the charger as
specified below:
9. Do not operate the charger with a damaged cord or plug. Replace them immediately.
10. Do not operate the charger if it has been dropped, has received a sharp blow, or has been other-
wise damaged in any ay. Return the unit to Isco for proper repairs.
11. Do not disassemble the Model 965 charger unless you are skilled in the diagnosis and repair of
electronic circuitry. Return it to Isco or take it to a qualified service person for repair if this is
needed. Improperly made repairs will voice repair if this is needed. Improperly made repairs
will void the warranty, and could result in shock or fire hazard.
12. The reduce the risk of electric shock, disconnect the Model 965 charger from AC power before
attempting any maintenance or cleaning. Turning off the controls will not reduce this risk.
13. Do not attempt to disassemble or troubleshoot the Model 965 Five-Station Battery Charger
unless you are skilled in the diagnosis and repair of electronic circuitry. Hazardous voltages are
present inside the charger and you could be killed or seriously injured if you come into contact
with them. Refer all servicing to qualified personnel only.

1.4 Grounding and AC
Power Connections
The Model 965 Five-Station Battery Charger should always be
grounded to reduce the risk of electrical shock. The charger has a
power cord with an equipment grounding conductor and a
three-pronged grounding plug. Attach this plug only to a
three-pronged outlet that is properly installed and grounded in
accordance with the National Electrical Code and all local codes
and ordinances.
WARNING
Before using the grounding adapter shown in Figure 1-3,
make sure the center screw of the outlet plate is grounded.
The green-colored rigid ear or lug extending from the
adapter must be connected to a properly grounded outlet.
Make certain it is grounded. If necessary, replace the
original outlet cover plate screw with a longer screw that
will secure the adapter ear or lug to the outlet cover plate
and make the ground connection to the grounded outlet.
The Model 965 Battery Charger is made for use on a nominal 120
or 240 volt 50-60 Hz AC circuit. The model supplied for use in
the U.S.A. and Canada has a 120-volt three-prong grounding
plug that looks like the plug shown to the left in Figure 1-3. A
temporary adapter can be used to connect this plug to a 2-pole
receptacle (as shown to the right in Figure 1-3) if a properly
grounded outlet is not available. The temporary adapter should
be used only until a properly grounded outlet can be installed by
a qualified electrician.
4
Connector for Charging Batteries
This connects to both Isco-made nickel-cadmium and lead-acid batteries.
5
Battery Selector Switch
This switch must be in the proper position for the type of battery (nickel-cadmium or lead-acid).
NOTE: You cannot charge both battery types at once!

Figure 1-3 Grounding Methods
DANGER
Never alter the AC cord or plug provided with the
unit, specifically by cutting off the third
grounding pin. If the plug will not fit into the
outlet, have the correct outlet installed by a
qualified electrician. If you fail to properly ground
the Model 965 charger, you risk electric shock.
You can verify grounding with an ordinary neon test light. Insert
one lead of the tester in the narrow or shorter (hot) slot of the
outlet. Put the other lead first into the wider (neutral) slot and
verify that the test lamp is glowing brightly. Then move this lead
from the wide slot (neutral) to the screw in the center of the
outlet plate. The test lamp should again glow brightly when you
touch the lead to the screw. If it does not, the screw (and probably
the rest of the circuit) is not grounded.

1.5 Operating
Instructions
The Model 965 Five-Station Battery Charger, when connected to
the appropriate AC power source, will properly charge either Isco
nickel-cadmium or lead-acid batteries. The charger provides a
regulated, current-limited 400 mA for the proper charging of
nickel-cadmium batteries, and a regulated voltage of 16 VDC
limited to 800 mA for charging lead-acid batteries.
Do not test either nickel-cadmium or lead-acid batteries for
state-of-charge by sparking the output (shorting the connectors
together). Be very careful inserting voltmeter probes into the
battery output connectors. Any accidents resulting in a shorted
battery output can damage the battery in less than three
seconds. Additionally, because the batteries are not internally
fused, the conductors from lead-acid batteries can weld together,
causing rapid heat buildup that may result in fire and serious
personal injury.
As many as five batteries of one type can be charged at the same
time with the Five-Station Battery Charger. To charge either
type of battery, simply attach the battery's connector to one of the
output connectors on the charger. Make certain the selector
switch is appropriate for the battery you are charging before
applying power. Generally the batteries (either type) will attain
full charge within 15 to 18 hours. Occasional or slight over-
charging of the batteries will not hurt them, but it is worthwhile
to avoid frequent or prolonged overcharging.
Prolonged overcharging of nickel-cadmium batteries causes
internal heating of the cells. This heating will eventually make
the nylon separator material deteriorate between the plates,
causing shorts and hastening end-of-life for the cell. Prolonged
overcharging of lead-acid batteries forces the battery to vent
water from the electrolyte. The vents are one-way and the water
cannot be replaced. The battery will “dry out” and fail from lack
of electrolyte.
When charging more than one battery, the internal electronics
must be cooled by the internal fan. For adequate ventilation,
allow at least 4 inches (10 cm) of space between the rear panel of
the charger and a wall or other equipment.
1.6 Maintenance The Five-Station Battery Charger has a 1-ampere circuit breaker
mounted on the rear of the charger cabinet. If the circuit breaker
trips, you can reset it by pressing the button. If the circuit
breaker trips again quickly or repeatedly, there is probably some-
thing wrong with the electronic circuitry. Check to make sure the
VOLTAGE SELECTOR switch is in the proper position for the
power source you are using. Verify that the BATTERY
SELECTOR switch is in the proper position for the type of
battery you are charging. If the circuit breaker still continues to
trip after you have checked all these things, there may be an
internal problem.
For cleaning, use water with a small amount of detergent. For
harder to remove stains, use isopropyl alcohol.
