SAVE THESE INSTRUCTIONS — this manual contains important safety instructions for the
Ideal Battery Isolator
IDEAL BATTERY ISOLATOR PRECAUTIONS
1. Never place the Ideal Battery Isolator directly above a battery; gases produced from the battery
will corrode or damage it.
2. Never allow battery acid to drip onto the Ideal Battery Isolator.
1. Always wear eye protection while working around batteries.
2. Batteries contain corrosive acid and produce gas as a by-product of their operation.
• If acid contacts your skin, neutralize it using a paste made from baking soda and water.
• If acid contacts your eyes, ush them with clean water and seek medical attention
immediately.
3. Never work near sparks or open ames, they could ignite the hydrogen gas produced by the
battery leading to re or explosion. Connecting the battery leads is one of the most common
causes of sparks.
4. Always work in a well ventilated area to prevent accumulation of battery gases.
5. Remove all metal personal items such as rings, watches, necklaces and bracelets before working
with the battery. A lead acid battery can product a short circuit current high enough to melt
metal and cause a severe burn.
6. When working near the battery, another person should be within range to come to your aid if
needed.
7. To prevent sparks and arcs and arcs from forming when connecting or disconnecting the battery:
• When connecting the battery, attach the positive lead before the negative.
• When disconnecting the battery, detach the negative lead before the positive.

Medical Equipment Notice
Analytic Systems does not recommend the use of their products in life support applications
where failure or malfunction of this product can be reasonably expected to cause failure of
the life support device or to signicantly affect its safety or effectiveness. Analytic Systems
does not recommend the use of any of its products in direct patient care. Examples of devices
considered to be life support devices are neonatal oxygen analyzers, nerve stimulators (whether
used for anesthesia, pain relief, or other purposes), auto-transfusion devices, blood pumps,
debrillators, arrhythmia detectors and alarms, pacemakers, hemodialysis systems, peritoneal
dialysis systems, neonatal ventilator incubators, ventilators for both adults and infants,
anesthesia ventilators, and infusion pumps as well as any other devices designated as “critical”
by the U.S. FDA
8. Before working, always make sure the unit is turned OFF. Make sure any devices connected to or
being powered by the battery are turned OFF.
9. Do not charge or load test a maintenance-free (VRLA) battery if its charge indicator dot is yellow,
clear or otherwise indicating insufcient electrolyte.
10.NEVER charge a frozen battery.
11.Use proper adapters to connect the charger leads to side terminal batteries.
12.Be extra careful not to drop a metal tool on to the battery. This can cause a spark or short-circuit
leading to re or explosion.
13.Clean the battery terminals regularly to prevent build up of corrosion. Be careful to keep corrosion
from coming in contact with your eyes.
14.Study all the battery manufacturer’s specic precautions such as whether to remove cell caps while
charging and recommended rates of charge

Introduction
Analytic Systems introduces the updated IBI2/3 series of battery isolators, allowing you to charge 2 bank
or 3 bank battery systems from a single alternator. Ideal for automotive, marine or trucking purposes,
the IBI also isolates the battery banks using Analytic Systems’ Ideal Diode technology preventing a
discharged bank from draining a charged one.
Ideal Diode technology uses MOSFET transistors and control circuitry in place of the diode used in
traditional battery isolators. By doing so, the IBI is able to operate with a fraction of voltage drop found
in diode-based battery isolators. At its maximum rated current the voltage drop is a miniscule 0.16V
and essentially zero at low currents. This way, all the power of the alternator is applied to the batteries
ensuring a full recharge every time.
A green LED indicator clearly shows that the IBI has been correctly connected.
The IBI is available in two models, the IBI2 for 2 battery banks and the IBI3 for 3 battery banks. The IBI1, a
custom high-current single battery bank isolator is also available by special order.

Mounting
Mount the unit in a convenient location between your alternator and battery banks, this location
should be clear and unobstructed for running cables between the three.
If mounting on a metal surface, the ground potential of the surface should be the same as the battery
negative. On a steel or aluminum boat this may not be the case for electrolysis prevention. In this case,
mount the IBI on a plywood board or other non-conductive material. Then mount that non-conductive
material to the vessel.
Make sure the screws mounting the IBI to the non-conductive material do not protrude through the
bottom of the material.
CAUTION: All connections must be securely made before starting the
engine.
Operation
Input Connection
The input connection connects the alternator to the battery isolator. To set up this connection:
1. Remove the existing wire from the alternator. Cover the lug with electrical tape or shrink tubing
and carefully move it aside. Secure it with a tie wrap.
2. Prepare a cable with a 5/16” ID lug on one end of the cable (End A). On the other end, attach a lug
suitable for connection with your alternator (End B)
3. Connect the End A of the cable to the Alternator Positive Connection. Connect End B of the cable to
your alternator.
Output Connection
The output connection connects the battery isolator to the battery banks. To set up this connection:
For each battery bank:
1. Prepare a cable with a 5/16” lug on one end (End A) . On the other end, attach a connector suitable
for the positive terminal of the battery bank (End B)
2. Connect End A to one of the Battery Positive Connections.
3. Connect End B to the positive terminal of the battery bank. Battery 1 connects to the HOUSE BANK
and Battery 2 or 3 (IBI3 model) connects to the ENGINE STARTING BATTERY
4. Connect the negative terminal of the battery bank to the ground.

8
Ground Connection
The IBI uses a ground reference to operate its control circuitry which it reads through the Ground
Connection. To set up this connection:
1. Prepare an AWG18 wire with a #10 lug on one end.
2. Connect this end of the wire to Ground Point.
3. Connect the other end of the wire to the battery negative terminal or directly the engine block. If the
ground is properly connected, the Grounding LED will be illuminated. This is a very high efciency
LED that requires only 1 milli-amp from 12 volts so it will never discharge the battery.
Ignition (IGN) Connection
The Ignition (IGN) Connection is an optional connection done by the installer. If you read a normal
charging current from your alternator to the battery banks after installing the IBI then you do not need
to make this connection.
If there is no charging current after installing the IBI, you may need to make an Ignition Connection.
Simply attach the original charging wire back to the alternator using a commonly available industrial
axial leaded diode such as a 1N4001 with the cathode (bar end) facing the alternator. The diode will
apply voltage from the battery to the alternator so it will start.
