• Incompatible, unmonitored and damaged batteries can explode if used with this product. Do not leave product unattended while it is in use. Do not attempt to charge a frozen or damaged battery. Only use this product with batteries of recommended voltage. Always operate this product in a well-ventilated area. Batteries generate explosive gases during normal battery operation. To lower the risk of a battery explosion, follow all safety information contained within as well as those published by the battery manufacturer.
• This product is an electrical device that emits heat and can cause burns if not operated properly. Do not smoke or use any source of electrical spark or fire when operating this product. Keep product away from combustible materials and never cover the product during operation.
• This product produces electrical currents that can shock and cause serious injury, including death. Do not cut any of connecting cables, submerge in water, or get wet.
• Working with batteries can cause exposure to battery acid that can cause eye and skin irritation Always wear eye protection when operating this product or working with batteries. In case of contamination of eyes or skin, flush affected area with running water and contact your local poison control immediately.

Precautions when working with the Battery Charger 2A:
Before using the charger, carefully read all instructions and warnings within this manual as well as the battery manufacturer’s specific precautions and recommended rates of charge for the battery. Make sure to determine the voltage and chemistry of the battery by referring to your battery owner’s manual prior to charging.
Do not expose charger to rain or snow.
The use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric shock, or injury to persons.
**** An extension cord should not be used unless absolutely necessary. Use of improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:

• That pins on plug of extension cord are the same number, size, and shape as those of plug on charger;
• That extension cord is properly wired and in good electrical condition; and
• That wire size is large enough for the AC current rating of the battery charger

Do not operate the charger with a damaged cord or plug.
Do not operate the charger if it has received a sharp blow, been dropped, or otherwise damaged in any way.
To reduce the risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning.
The main unit connector cable cannot be replaced. If the cord is damaged the charger should be scrapped.
Precautions when working with vehicle batteries:
WARNING: Explosion and fire hazard

1. Follow all instructions published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.
2. Make sure the area around the battery is well-ventilated.
3. Never smoke or allow a spark or flame in the vicinity of the engine or batteries.
4. Be careful not to drop a metal object on the battery or allow a metal tool to simultaneously touch the positive and negative cable ends or battery terminals.
5. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with batteries. Batteries produce a short-circuit current high enough to weld a ring or other similar objects to metal, causing a severe burn.
6. If you need to remove a battery, always remove the negative terminal from the battery first. Make sure all accessories are off to prevent causing a spark.
7. Someone should be within range of your voice, or close enough to come to your aid when you work near batteries.
8. Have plenty of fresh water, soap and a supply of baking soda on hand in the area of the batteries in case of contact with battery acid. Baking soda neutralizes lead acid battery electrolyte.

2. Connect the negative (black) alligator clamp or O-ring terminal to the negative battery terminal or vehicle chassis.

3. Connect the opposite end of your cable to the battery charger main cable.

4. Connect the battery charger into a suitable electrical outlet.

5. Determine which connection type is needed (Alligator or O-ring)

6. Connect either the alligator clamps or O-ring terminals to your battery.
   (First, red to positive, then black to negative).

7. Connect the opposite end of your cable to the battery charger main cable

8. Plug the battery charger into a suitable electrical outlet

Charging Modes
The Cobra Battery Charger 2A has multiple charging modes designed to handle a wide range of battery types and voltages. Always check with the battery manufacturer to verify your battery’s specifications and confirm the right charge mode required for your specific battery. Do not operate the charger until you have confirmed the correct charge mode required for your battery.

battery. You will see the standby power indicator illuminated orange until you
connect your battery charger, select a charging mode and begin to charge your battery. At that point, the power indicator will turn off and the main LED status light will begin to blink orange indicating that charging has started.
12V| This mode is for charging standard 12V lead acid batteries (Wet Cell, Gel Cell, Enhanced Flooded and Maintenance Free batteries)
12V AGM| This mode is for charging 12-Volt AGM batteries
12V Lithium| This mode is for charging 12-Volt Lithium-ion batteries, including lithium iron phosphate.
6V| This mode is for charging standard 6V lead acid batteries (Wet Cell, Gel Cell, Enhanced Flooded and Maintenance Free batteries). Press and hold for two (2) seconds in order to enter 6V charging mode.
Low Voltage Mode| Low Voltage mode is intended for charging batteries whose voltage has dropped too low to be detected normally. If the battery charger has been
unable to detect your battery voltage due to it being too low, press and hold for six (6) seconds in order to enter Low Voltage Mode. At this point
all modes will flash. Select your desired charging mode and the LED status light will begin to flash between green and red indicating that Low
Voltage Mode charging has begun. Low Voltage Mode will charge for five (5) minutes, after which the battery charger will return to normal charging
operation.*

*Caution: Using Low Voltage Mode bypasses certain safety functions of the battery charger. Check that all connections have been made prior to entering Low Voltage Mode and do not touch the end connectors together once Low Voltage Mode has been activated. Risk of sparks, fire, explosion, property damage, injury and death can occur if not operated properly.
