Frequently Asked Questions - HYCH405 HYUNDAI

How do I charge a battery with the HYCH405?

Connect the red clamp to the positive terminal and black clamp to negative. Plug into mains. The charger automatically detects the battery voltage and starts charging. The LED indicator will show charging status.

Can this charger handle a completely dead battery?

Yes, the HYCH405 can charge batteries from 2V up, but if the battery voltage is below 2V, the charger may not detect it. Try a known good battery to confirm.

What types of batteries are compatible?

It is designed for 12V and 6V lead-acid batteries including flooded, AGM, and gel types. Do not use for lithium-ion or NiMH batteries.

How do I know when the battery is fully charged?

The fully charged LED will turn solid green (or similar) and the charger switches to maintenance/trickle mode. You can leave it connected indefinitely.

Is it safe to leave the charger connected overnight?

Yes, once fully charged, the charger enters maintenance mode to keep the battery topped up without overcharging. It is safe for long-term connection.

What does the error LED indicate?

The error LED may indicate reverse polarity, short circuit, or a battery with extreme low voltage. Check connections and battery condition.

Can I charge a battery while it is still in the vehicle?

Yes, but ensure the vehicle ignition is off and the battery terminals are accessible. Connect directly to the battery, not to the vehicle chassis to avoid grounding issues.

What is the maximum battery capacity this charger can handle?

The 4A output is suitable for batteries from about 20Ah to 120Ah. For larger batteries, charging may take more time.

How do I clean and maintain the charger?

Unplug the charger and wipe with a dry cloth. Ensure the clamps are clean and free of corrosion. Store in a dry, cool place.

Where can I find spare clamps or fuses?

Spare parts are available from Hyundai service centers or authorized dealers. The internal fuse is a standard 5A glass fuse.

If an accident happens with injuries or third parties are injured, carry out the first aid measures most suitable for the situation immediately and contact the medical authorities for any necessary health care. Carefully remove any debris that might cause damage or harm persons or animals should it not be seen.

▲Battery Charger

• Do not place any objects on the battery charger and do not place the battery charger on soft surfaces. There is a risk of explosion.
• If other batteries are used, e.g. imitations, reconditioned batteries or third-party products, there is a risk of injuries as well as damage caused by exploding batteries.
• A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. This may cause an internal short-circuit and the battery to burn, smoke, explode or overheat.

⚠Battery Use And Care

• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
• Liquid ejected from the battery may cause irritation or burns.
• Never attempt to open the battery pack for any reason. If the plastic housing of the battery pack breaks open or cracks, immediately discontinue its use and do not recharge it.
• Do not pierce the battery with nails, strike the battery with a hammer, step on the battery or otherwise subject it to strong impacts or shocks.
• Protect the battery pack against heat. Do not place the battery in direct sunlight or use or store the battery inside cars in hot weather. Doing so may cause the battery to generate heat, explode or ignite.
• Never try to charge a battery pack that is cracked or damaged in any other way. There is a danger of electric shock or electrocution.

- There is an explosion risk if the battery terminals are short circuited, when

connecting/disconnecting ALWAYS exercise great care so that the terminals or battery leads are NOT allowed to touch and cause a spark. ALWAYS use suitable insulated tools.

▲Electrical Safety

DANGER!

ELECTRICITY CAN KILL - NEVER WORK ON LIVE/ENERGISED EQUIPMENT.

• Prior to carrying out any maintenance work you MUST identify electrical isolation methods and isolate all electrical supplies.
• Prior to use and with all electrical supplies isolated, you MUST check all electrical cables, plugs and connectors for the following;
• Are intact and have no signs of damage, to include but not limited to bare wires, chaffing, cuts and loose wiring.
• If there are any signs of damage, the damaged item MUST be taken out of service until the damage has been repaired by an electrically competent person.
• All trailing cables should be routed so as not to cause any kind of trip hazard.
• NEVER work on or near electricity with wet hands, wet clothing and wet gloves.
• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges and moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

▲Unboxing Safety

WARNING! Unboxing and assembling the machine should be done on a flat, stable surface with enough room. Disposal of the packaging should be done in accordance with the local regulations in force.

Carefully remove the product from the packaging and examine it for any sign of damage caused during shipping. Lay the contents out and check them. If any part is damaged or missing, you must not use the machine. Contact HYUNDAI Power Products immediately. You must keep the packaging material in case the machine needs to be returned or repaired.

WARNING! Some of the packaging material may be harmful to children. Keep out of reach of children.

Transport

The equivalent lithium content of the batteries included in the product package is below the appropriate limit values. Therefore the battery as an individual component as well as the power tool and its product package are not subject to national or international dangerous goods regulations as the standard 2.5Ah battery is not over the 100wh limit.

If several machines with lithium-ion are transported, these regulations may become relevant and special measures may be required (e.g. for the packaging).

CAUTION! Do not post batteries which have a damaged casing.

Using The Battery

Battery Status

The LED light indicates the state of charge of the battery.

• 4 LED lights lit = 100% battery power

Press the button to check the battery status.

The indicator will go out after 5 seconds.

If the LED flashes, the battery must be recharged. If the LED does not light up after the button is pressed, the battery is faulty and must be replaced.

Charging The Battery

1. Plug the charger into an AC outlet 220-250V (normal household voltage).
2. Insert the battery into the slots of the charger and slide into place until the battery locks into place.
3. The LED will flash green while the battery is charging.
4. Once the battery is fully charged, the LED indicator will show a steady green light.
5. Remove the battery by pressing and holding the latch button and sliding out of the charger.
6. Do not leave the battery on the charger. Remove it when it is fully charged.
