Nitecore Digicharger D4 V2 Li-ion / NiMH / LiFePo4 battery charger
Charge stuff. Automatic charger with LCD display for showing voltage, charge current, and time to charge.

The Digicharger D4 is a universal, automatic smart-charger compatible with almost all types of rechargeable batteries thus eliminating the need to own several chargers. The D4 is able to automatically identify Li-ion, Ni-MH and Ni-Cd rechargeable batteries and apply an appropriate charging mode (Constant Charge Current (CC), Constant Charge Voltage (CV) and Trickle Charge). Each of the D4's four microcomputer-controlled charging slots is capable of monitoring and charging batteries independently. Additionally, yellow and blue power/charging status indicator lights could visibly indicate battery status and charging process.

·Capable of charging 4 batteries with different chemistries simultaneously
·Each of the four battery slots monitors and charges independently
·Compatible with and identifies Li-ion (26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500, 10440), Ni-MH and Ni-Cd (AA, AAA, AAAA, C) rechargeable batteries
·Optimized charging design for IMR batteries
·Features three charging modes (CC, CV and Trickle Charge)
·Automatically detects battery status and selects the appropriate voltage and charge mode
·Automatically stops charging when complete
·Features over-charge prevention to protect batteries
·Features temperature monitoring to prevent overheating
·Made from durable ABS (fire retardant / flame resistant)
·Features reverse polarity protection
·Designed for optimal heat dissipation
·Certified by RoHS, CE, FCC, CEC and KC
·Insured worldwide by Ping An Insurance (Group) Company of China, Ltd


Important notes:
When charging a single battery in the D4, the charging current can reach as high as 750mA, which exceeds the current many Ni-MH/Ni-Cd AAA and 10440 Li-ion batteries can withstand. For this reason, under no circumstances should a single AAA or 10440 battery be charged on its own, as potential overheating, damage or even explosion may occur. Due to the aforementioned reasons, it is recommended that a minimum of two (2) AAA or 10440 rechargeable batteries are placed into the charging slots together.
When charging two batteries in the D4, be sure to always place them in either slot 1 and 3 or slot 2 and 4.
When charging different battery types simultaneously (for example, li-ion 26650 and AAA), always ensure solid contact is made between both sides of the battery and the charging slot's metal contact points.The D4 is restricted to charging Li-ion, LiFePo4, Ni-MH and Ni-Cd rechargeable batteries only.
Never use the D4 for other types of batteries as this could result in battery explosion, cracking or leaking, causing property damage and/or personal injury.The D4 should only be used indoors or inside a motor vehicle.
Do not expose it to water, high humidity, low or high ambient temperatures.
Do not disassemble or modify the charger.
Children under the age of 18 should be supervised by an adult when using the D4.The D4's safe operating temperature is between 0c-40c.Do not use or store the charger near open flames, direct sunlight, heating devices or other high-temperature environments. <inline st
