The Accupower IQ-338XL Universal LCD Smart Charger/Analyzer is a state-of-the-art charging solution designed for Li-ion, NiCd, and NiMH rechargeable batteries. With its advanced features and intelligent microprocessor, the IQ-338XL can charge and analyze up to four batteries simultaneously, making it ideal for users with multiple devices that require rechargeable batteries.

One of the key features of the IQ-338XL is its ability to automatically identify the chemistry of the battery being charged. This means that it can detect whether the battery is Li-Ion, NiMH, or NiCd, and adjust the charging process accordingly. Additionally, each of the four battery slots monitors and charges independently, ensuring that each battery is charged to its full capacity without overcharging or overheating.

The LCD display on the IQ-338XL is another standout feature. The display shows real-time information about the charging status, capacity, voltage, charging current, operating time, and internal resistance of each battery. The backlighting on the LCD screen also makes it easy to read the display in low-light conditions.

The charging current on the IQ-338XL is adjustable, with settings of 500mA, 700mA, 1000mA, and 1500mA available. This allows users to customize the charging current to suit the specific needs of their batteries. The discharge feature with battery analyzer is another unique feature that measures and tests the battery capacity before and after charging, helping users identify batteries that need to be replaced.

The IQ-338XL also comes with overheat protection, which uses temperature sensors to prevent the batteries from overheating or overcharging. This feature ensures that the batteries are charged safely and efficiently, without causing any damage to the battery or the charger itself.

With its USB charging socket, the IQ-338XL is also capable of charging USB-powered devices like smartphones and tablets. This is a useful feature for users who need to charge multiple devices at once, as they can charge both their batteries and their USB-powered devices at the same time.

In terms of compatibility, the IQ-338XL works with a wide range of batteries, including 3.7V Li-ion batteries like 10440, 14430, 14500, 16340 (RCR123), 17335, 17500, 17670, 18490, 18500, 18650, 18700, 22650, 26650, 26700, and 33700. It also works with Ni-MH and Ni-CD batteries like 9 Volt, A, AA, AAA, C, D, and Sub C.

The Accupower IQ-338XL Universal LCD Smart Charger/Analyzer is a versatile and advanced charging solution for users who need to charge multiple rechargeable batteries at once. With its intelligent microprocessor, adjustable charging current, LCD display, overheat protection, and USB charging socket, the IQ-338XL offers a safe and efficient way to charge and analyze rechargeable batteries.
