IMPORTANT SAFETY INSTRUCTIONS
SAFETY PRECAUTIONS FOR WORKING IN THE PROXIMITY OF A BATTERY
1) Batteries generate explosive gases during normal operation. Use in well-ventilated area.
2) Consider having someone close enough or within the range of your voice to come to
your aid when you work near a battery.
3) Do NOT smoke, strike a match, or cause a spark in Proximity of battery or engine.
Avoid explosive gas, flames and sparks.
4) Remove all personal jewelry, such as rings, bracelets, necklaces, and watches while
working with a vehicle battery. These items may produce a short-circuit that could cause
severe burns.
5) Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark
or short-circuit a battery or other electrical hardware which may cause an explosion or fire.
6) Wear complete eye protection, hand and clothing protection. Avoid touching eyes while
working near a battery.
7) Study all battery manufacturer’s specific precautions such as removing or not removing
cell caps while charging and recommended rates of charge.
8) Clean battery terminals before connected with the charger. Be careful to keep corrosion
from coming in contact with eyes.
9) When it is necessary to remove a battery from vehicle to charge, always remove
grounded terminal from battery first. Make sure all accessories in the vehicle are off in
order to prevent an arc.
10) It is NOT intended to supply power to an extra-low-voltage electrical system or to
charge dry-cell batteries. Charging dry-cell batteries may burst and cause injury to persons
and property.
11) NEVER charge a frozen, damaged, leaking or non-rechargeable battery.
12) If battery electrolyte contacts skin or clothing, wash immediately with soap and water.
If electrolyte enters eye, immediately flood eye with running clean cold water for at least
15 minutes and get medical attention immediately.
SAFETY PRECAUTIONS FOR USING THE CHARGER
1) Do NOT place the charger in the engine compartment or near moving parts or near the
battery; place as far away from them as DC cable permits. NEVER place a charger directly

above a battery being charged; gases or fluids from battery will corrode and damage
charger.
2) Do NOT cover the charger while charging.
3) Do NOT expose to rain or wet conditions.
4) Connect and disconnect DC output only after setting AC cord from electric outlet.
5) Use of an attachment not recommended or sold by the manufacturer may result in a risk
of fire, electric shock or injury to persons.
6) Do not overcharge batteries by selecting the wrong charge mode.
7) To reduce the risk of damage to electric plug and cord, pull by the plug rather than the
cord when disconnecting charger.
8) To reduce risk of electric shock, unplug charger from outlet before attempting any
maintenance or cleaning.
9) Operate with caution if the charger has received direct hit of force or been dropped.
Have it checked and repaired if damaged.
10) Any repair must be carried out by the manufacturer or an authorized repair agent in
order to avoid danger.

CONNECTING TO THE BATTERY
1) Identify polarity of battery posts. The positive battery terminal is typically marked by
these letters or symbol (POS,P,+). The negative battery terminal is typically marked by
these letters or symbol (NEG,N,-).
2) Do not make any connections to the carburetor, fuel lines, or thin metal parts.
3) Identify if you have a negative or positive grounded vehicle. This can be done by
identifying which battery post (NEG or POS) is connected to the chassis.
4) For a negative grounded vehicle (most common): connect the RED POSITIVE clamp /
ring connector first to the positive battery terminal, then connect the BLACK NEGATIV
clamp / ring connector to the negative battery terminal or vehicle chassis.
5) For a positive grounded vehicle (very uncommon): connect the BLACK NEGATIV
clamp / ring connector first to the negative battery terminal, then connect the RED
POSITIVE clamp / ring connector to the positive battery terminal or vehicle chassis.
6) When disconnecting, disconnect in the reverse sequence, removing the negative first (or
positive first for positive ground systems).
7) Follow these steps when using 12V accessory plug: keep the vehicle hood open.

Connect the end of the 12V accessory plug to the charger; insert the 12V accessory plug
into the vehicle’s 12V outlet. If the vehicle’s ignition key has to be on in order for the 12V
outlet to supply / receive power, turn the key, without starting the engine.
8) A marine (boat) battery must be removed and charged on shore. To charge it on board
requires equipment specially designed for marine use.
CHARGING MODES
AQ7000 has nine modes: Standby,12V NORM, 12V COLD/AGM, 24V NORM, 24V
COLD/AGM, 12V AGM+, 12V LITHIUM, REPAIR and 13.6V SUPPLY. Some charge
modes must be held for three (3) seconds or / and pressed to enter the mode. Do not
operate the charger until you confirm the appropriate charge mode for your battery.

(Hold & Press) –––
Converting to a DC power supply for powering 12V
DC device or as a memory retainer when replacing
a battery (Yellow LED)
These “Hold or / and Press” modes are advanced charging modes that require your
full attention before selecting.
Using 12V AGM+ (Hold)
This mode is designed for 12V advanced AGM batteries only. Advanced AGM batteries
are typically found in startstop micro-hybrid vehicles. These batteries accept a higher than
normal charging voltage. 12V AGM+ charge mode is NOT suitable for traditional AGM
batteries. Consult the battery manufacturer before using this mode.
Using 12V LITHIUM (Hold & Press)
This mode is designed for 12V lithium-ion batteries only, including LiFePO4. Some
lithium-ion batteries may be unstable and unsuitable for charging. Consult the lithium
battery manufacturer before charging and ask for recommended charging voltage and
current.
Using REPAIR (Hold & Press)
This mode is for LEAD-ACID batteries only. It is an advanced battery recovery mode for
repairing old, idle, stratified or sulfated batteries. NOT all batteries can be recovered. For
optimal results, take the battery through a full charge cycle, bringing the battery to full
charge, before using this mode. When this mode is chosen, do remember press Mode
button for choosing appropriate 12V Mode(s) or 24V Mode(s). One REPAIR cycle can
take up to eight (8) hours to complete the recovery process and will enter to charge (8
steps charging cycle) when completed. This mode uses a high charging voltage and may
cause some water loss in WET cell batteries. Plus, some batteries and electronics may be
sensitive to high charging voltages. To minimize risks, disconnect the battery from the
vehicle before using this mode.
Using 13.6V SUPPLY (Hold & Press)
This mode converts the charger to a constant voltage, constant current DC power supply.
It can be used to power 12VDC devices. Prior to use, read your 12VDC device manual to
determine if it is suitable for use with this mode. As a power supply, it can also be used to
retain a vehicle’s on-board computer settings during battery repair or replacement. 13.6V

Supply Mode provides 13.6V at 5A with overload protection at 6A (Max). Both spark
proof and reverse polarity protection are disabled in this mode. Do NOT allow the positive
and negative battery clamp or ring terminal to touch or connect to each other as the charger
could generate sparks.

CHARGING STEPS
STEP 1: DIAGNOSIS (Check if battery has connected with the charger and also check
battery voltage)
STEP 2: DESULPHATION (If battery voltage is too low, programs automatically
generate pulsing current to remove sulphate, up to 5 hours)
STEP 3: ANALYSE (Check if the battery voltage reaches to the threshold after
desulphation, and charging begins if the battery voltage is OK)
STEP 4: SOFT START (Charge with echelon constant current)
STEP 5: BULK (Charge with constant maximum current until battery voltage is reached
to the threshold)
STEP 6: ABSORPTION (Provide gradually declining current charge for maximum
battery voltage)
STEP 7: ANALYSE (Test if the battery can hold charge)
STEP 8: MAINTENANCE (Continuously monitor the battery, and charging current will
intelligently adapt to the variable battery voltage)
