Frequently Asked Questions - IQ-312 AccuPower

What types of batteries can the IQ-312 charge?

The IQ-312 can charge NiMH, NiCd (AA/AAA) and Lithium-ion batteries (such as 18650, 14500) with appropriate voltage.

How do I use the charger?

Insert batteries into the slots respecting polarity, plug in the power adapter, and slide the charge rate switch if needed. The LED indicates charging status.

How long does it take to charge batteries?

Charging time depends on battery capacity and selected rate. For example, a 2000mAh NiMH will take ~2 hours at 1A, or ~4 hours at 0.5A.

Can I charge different battery types at the same time?

No, each slot operates independently but all batteries should be of the same chemistry for best results. Mixing types may cause improper charging.

What do the LED indicators mean?

Red: charging. Green: charged/full. Flashing red: error or faulty battery. Refer to manual for detailed legend.

Is the charger safe to leave unattended?

Yes, the IQ-312 has overcharge, overheat, and reverse polarity protection. However, it is recommended to monitor charging for safety.

What power sources does the charger accept?

It comes with an AC adapter for mains (100-240V) and a car adapter (12V) for portable use.

How do I clean the charger?

Disconnect from power, wipe with a dry cloth. Do not use liquids or aerosols.

What should I do if a battery gets hot?

Remove the battery immediately if it becomes excessively hot. The charger has thermal protection, but extreme heat may indicate a faulty battery.

Where can I find spare parts or support?

Spare parts are not sold separately. For support, contact AccuPower customer service or visit the official website.

USER MANUAL IQ-312 AccuPower

Please read the manual carefully before using this charger.

We thank you that you have decided to purchase our intelligent charger.

Please follow the safety and care instructions in this manual, to be able to use this device efficiently and safely.

Included Delivery:

• Charger IQ312
• Power supply
• User Manual

Important Notes:

• Use the IQ312 charger only with Li-Ion / LiMnO2 cells with 3.6V-3.7V and NiCd, NiMH cells with 1.2V rechargeable batteries.

• With the IQ312 you can automatically charge the following types of cells:
  Li-lon: 26700, 22650, 21700, 20700, 18650, 18500, 18490, 17670, 17500, 17355, 16340 (RCR123), 14500, 10440
  NiMH/NiCd: AA, AAA, A, Sub-C, C

• Do not use the charger with other types of batteries (for example: Alkaline or other Systems).

• Use the charger only in dry and closed rooms with normal conditions.
• If the charger is not in use, we recommend disconnecting the power cable from the socket.
• During the charging process, you should not leave the charger unattended.

- Keep the batteries out of the reach of children.

- Always use the right charging current for each battery. You can find the right current in the manufacturers specification.

- When new batteries are in use for the first time, it might be required that the batteries need to be charged and discharged several times before they reach their optimum capacity.

- The charger must be used on a non-flammable base.

- Heat gets produced if batteries get charged. It is very important to ensure that the charger is placed in an incombustible area (pay attention to carpets, paper, flammable liquids, furniture and so on).

Input:

DC 12V / 3,2A

Output:

Twelve independent slots

Button Functions:

- "Light On" Button

Display:

During the charging process, the following values are shown on the display:

• Battery symbol
• Slot number
• Charging current (mA)
  • State of charge (25%, 50%, 75% und 100%)

LC Display

Charging function:

The IQ312 works in a mode called „ Current Auto Set Mode “. This means, for every inserted battery, the current is set automatically. This feature allows a simple and safe use of the charger. The automatically chosen charging current depends on the chemistry the inserted battery has, regardless of its size or capacity. All twelve channels are independent, so every channel can be occupied by different batteries, that are distinguished as follows:

Type 1: NiMH, NiCd:
Please insert your batteries in your IQ312. The charger can be powered before or after inserting the batteries, it makes no difference for the functionality. After the charger recognizes the NiMH or NiCd cells, the charging process starts automatically. The current gets set to 500mA for each slot.

Type of battery Charging current per slot
- mA
NiMH, NiCd 500

Table 1: Charging current for NiMH and NiCd
After the charger has accepted the battery, the display lights up for 30s and signalizes hereby that the battery is alright and ready to charge. Also a charge-current-arrow of the according channel on the display shows that the battery is already charging.
Also visible on the display, there are bars that show the actual state of charge of each channel.

Type 2: Li-Ion:

Charging Li-Ion batteries works the same as charging NiMH or NiCd batteries. You can insert your batteries before or after powering the charger. That makes no difference in functionality. Now there are two options how to choose the charging current for each battery. It depends on which slots are used.
Every two adjacent slots (e.g. slot 1 and 2; slot 3 and 4; slot 5 and 6 and so on) are paired and share their power. If only one of two paired slots (e.g. slot 5 is empty and slot 6 is charging) are occupied by a Li-Ion battery, then the charging current is set to 1000mA.
Otherwise if both paired slots are occupied, the charging current gets shared and every slot is sourced with 500mA.

Battery Type Charging current if one of two paired slots is occupied	Charging current if both of two paired slots are occupied
- mA mA
Li-Ion 1000 500

Tabelle 2: Charging current for Li-Ion

Charging has finished:

If the charging process has finished, the charger signalizes it clearly with a flashing of the display backlight three times in a row. This procedure looks the same for any type of battery. Further, the charging bars on the display become stable, that also shows that the according battery is fully charged.

„Light On“ - Button:

With the aid of the "Light On" button you can turn on the display background light by pressing the button once. If the button gets pressed and held down for a few seconds, the display background light flashes once, that signalizes the background light is now turned on permanently. If you want to turn off the background light again, you must press and hold the button again for a few seconds until the display flashes again.

Maintenance:

The chargers are maintenance free but should be cleaned sometimes. The charger should be disconnected from the power supply before cleaning. Use only soft and dry tissues (like cotton textiles) do not use any liquid.
