Features
Thank you for your purchase of the Xtreme Charge®QuadLink®from PulseTech®
Products Corporation.
PulseTech®Products Corporation (www.PulseTech.net) is nationally recognized for
its innovative technologies specifically designed to improve 6/12V battery perfor-
mance, trim replacement costs by extending battery life cycles and contributing to
the nation’s environmental movement to think and act Green by keeping batteries
healthy and out of the waste stream, landfills and smelters.
With the development of the QuadLink, Xtreme Charge®has multiplied this useful
application by 4 times—turning any 6V or 12V DC battery charger (using the stan-
dard 2-prong output connector) into a 4-station maintenance charger.
There’s no more need to spend time or to remember to switch back and forth
between vehicles or batteries in storage. Utilizing a simple, plug and play system,
QuadLink automatically splits and distributes 10-minute charge segments to up to
four batteries.
Applications include a wide variety of vehicles and equipment, including automobiles,
light trucks, SUVs, motorcycles, motor homes, small boats and watercraft, lawn
mowers and equipment, ATVs and even golf carts. When mated with a typical
maintenance charger (see User Guide) the QuadLink’s microprocessor automatically
adapts to the number of batteries actually connected.
Included with your QuadLink purchase:
1 – QuadLink 4-station charger multiplier
4 - Eyelet lug adaptor cables
4 - 5' extension leads
(Additional 5'and 25' lead extensions available separately)

User Guide
1
Do not operate without first reading these important safety notices and use instructions.
Additionally, do not use this without first reading important safety notices and use
instructions that come with your battery charger/maintainer and your battery.
NOTE: As part of good safety routine, this product is designed for use only with automatically controlled
charger maintainers and is optimized for use with the Xtreme Charge family of products. It is not
suggested for use with manual maintenance chargers that cannot be used without constant supervision.
1. Inspect all cable leads and connections to be sure that they are all in good working condi-
tion. Never use cable leads or clips that are worn, damaged or frayed in any way. Replace
worn or damaged leads prior to use. Do not alter or otherwise modify cables as this could
cause an unsafe condition possibly resulting in personal injury, explosion or fire.
2. Connect the output of your battery charger/
maintainer to the input of the QuadLink.
Note: The charger must have the same industry
standard 2-prong connector to mate properly
with the QuadLink.
3. Connect the extension leads that come with the QuadLink to either the standard attached
battery eyelet connector on each vehicle battery and/or to the charging clip set that comes
with your charger. Be sure to first connect the red battery clip to the positive (+) battery
terminal. Then connect the black battery clip
to the negative (-) battery terminal. Also, be
sure to double check that your attached eyelet
terminal cable sets are properly polarized.
Once you have connected the cable leads to
all batteries in use, you can begin the battery
maintenance process by plugging in your
charger to your AC power source.
4. What is happening:
A. Your battery charger is still in full control of the charging processes. Always refer to the
battery charger manufacturer’s instructions or the user interface on your charger to
determine what state of charge your battery is in.
B. The QuadLink is almost transparent to the battery. It does not add to the charging
capabilities of your charger, just to the number of batteries being maintained. Your
charger is still the “brain” in the system.

C. A blinking green LED light will indicate the first battery
connected to the QuadLink. Once additional batteries are
connected, a solid glowing green LED light will verify
connection to all additional connected stations. Once the
charger is connected to the QuadLink and plugged into the
AC power source, the charging cycle begins. From this point
forward, the station or battery that is currently “live” or
being charged is indicated by a blinking green LED light.
D. Every 10 minutes, the QuadLink will switch to the next battery in line. If there is no
battery connected to any given channel, the channel will be skipped after a short qualifi-
cation process.
E. Cycle rotation will continue indefinitely, maintaining the
charge of all 4 batteries for you automatically. The
QuadLink distributes your charger’s full power, moving
from battery to battery in 10-minute increments.
F. If you would like to remove a battery from the chain, it is
always best to unplug the QuadLink from the charger and
the charger from the AC power source first. Once the battery
is disconnected and the units are plugged back in, the
QuadLink will reset and recognize the batteries in the circuit
and skip any open channels after a circuit verification test.
G. If you replace or add a battery to an open channel, again it is always best to unplug
the QuadLink from the charger and the charger from the AC power source first. Once
you have connected the new battery to the circuit and plugged the units back in, the
QuadLink will reset and recognize the additional battery in the circuit and begin the
process again.
Use Comments and Suggestions:
1. If you are putting a vehicle/battery away for an extended period, it is always best to give
the battery a good charge on its own for a few days and test it prior to putting it away for a
season or any extended period. This will assure that proper storage maintenance will occur
without a hitch.
2. If there is ever a power outage, it is likely that during the outage, the charger may and the
QuadLink will consume a small amount of power via LED light indication of the batteries’
state of charge and channel indication. This is common and will not cause noticeable dis-
charge of the batteries in the circuit unless the power is out for an extended period of time.
Note: If either AC input power to the charger or DC power from the charger to the QuadLink
is purposely disconnected for any extended period for any reason, disconnect the QuadLink
from the batteries in the circuit until power is restored. This will assure that the batteries are not
unintentionally discharged.

3. If for any reason the QuadLink is not unplugged from the DC power source and allowed
to reset during removal of a battery, the LED channel indicator will remain illuminated
until the next cycle provides a circuit verification test indicating an open circuit. The output
previously associated with the removed battery will then in turn be skipped.
4. For use more customized to your specific needs, including additional 5' extension leads
(part #100X805) and 25' extension leads (part #100X825), please visit www.PulseTech.net.
Additional Functionality:
The QuadLink is also uniquely designed to
provide a very useful service of maintaining the
state of charge of multiple 6V or 12V batteries
in 24, 36 and 48V series connected configura-
tions typically used in Golf Carts or similarly
designed vehicles or battery packs.
The user would simply connect each output
lead using the provided eyelet lug connectors
(up to 4) to each of the 6V or 12V segments of
the multiple battery configurations and in doing
so allow the QuadLink to maintenance charge
each of the 6V or 12V segments of the pack in
10-minute intervals. This will ensure that the
entire pack is maintained at the state of charge
that they were left at when stored or left unused
for an extended period.

Frequently Asked Questions
1. Can the QuadLink be used with a Solar Charger? YES, if the Solar Charger uses the same connector, is 6V or 12V
DC and does not exceed 8 Amp output.
2. Is the QuadLink water resistant? YES, it is water resistant but not waterproof. It cannot be submerged or left in
pooled water or driving rain. Safety dictates that one should never use an electrical product in wet conditions.
3. Does the “bad battery” function still work when using the QuadLink? The QuadLink is not a charger but a
charge conduit. If your charger has a “bad battery” indicator, it will work through the QuadLink connection.
4. Will the QuadLink work if batteries are connected to first, second, and fourth outlet, skipping the third
position? YES, the QuadLink will sense the open circuit and skip it after a few seconds.
5. Will the QuadLink work on multiple battery types and styles simultaneously? For instance, AGM and Gel or
Deep Cycle marine and small Motorcycle batteries all connected to each of the 4 stations? YES, your charger
is still the “brain” in the system. If your charger has the ability to properly charge all of these battery types automati-
cally, the QuadLink will allow it. If your charger has to be manually switched to alternate settings to enable proper
charge output for these different battery types, the answer would be NO. If this is your situation, we suggest using
the Xtreme Charge to charge multiple battery types automatically.
6. Knowing that the QuadLink is optimized for use with the Xtreme Charge battery charger; does it also work
with other brands of chargers? YES, as long as your charger is fully automatic and utilizes the same DC connector.
7. When connected to Gel, maintenance free and AGM battery with a charger that requires the use of a battery
selection dial for charging different battery types, what happens? We suggest that you do not use the QuadLink
with this type of charger. Consider buying an Xtreme Charge to properly charge all these types on the QuadLink au-
tomatically.
8. If there is no battery connected, is power flowing to the battery clips or eyelet connector? The answer is NO
if you are using a fully automatic charger and it is functioning properly. We suggest that a manual charger NOT BE
USED with the QuadLink. Remember, the charger is always in control of the charge process, not the QuadLink.
9. Can I use this on my vehicle that has 4 batteries connected in parallel (in a 12V system)? YES, as long as
you are connecting only one station lead to this 12V pack. Although it will cause no harm, we do not suggest the
QuadLink be used in a parallel connected multi battery scenario as there is no additional charging benefit when com-
pared to single station charging to the pack.
10. Can I start my vehicle with the QuadLink still attached? YES, as long as your charger allows this capability. The
QuadLink does not control the charge going into the battery; it is only a conduit for the power going to each station.
11. Can I change the timing so that one battery charges longer before moving to the next battery? NO, the micro-
processor is not adjustable.
12. Can I connect two sets of leads to one battery so it will charge for an extended period? YES, if you want to
allow a certain battery to have more relative charge time within the charge cycle, you can “double connect” a
station to any given battery. This will give that battery 10 additional minutes of charge time per cycle.
