Description

The battery charger lithium (li-ion) for batteries in a compact size, the Xtar D4 features a smart yet easy-to-use three-phase charging. The Xtar D4 battery charger charges all 3.6V/3.7V lithium batteries in sizes: 14500, 14650, 16340, 17335, 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700, 22650, 26550.

What is three-step TC/CC/CV charging?

It keeps battery cells in good condition for a long time by charging at the appropriate voltage at all stages, and by cutting off the charging at the appropriate time. The three charging steps are:

  • TC (Trickle Charge) Wake-up: Deep discharged cells at less than 2.9 V are brought to life at a lower voltage
  • CC (Constant Current) Constant current: The battery cell is charged with a constant current when the voltage exceeds 2.9V. The charging current of the Xtar D4 battery charger can be 2x2A/4x1A/2×0, 5A (CH2 & CH3) + 2x1A.
  • CV (Constant Voltage) Constant voltage: When the battery is almost fully charged, the charger will start to reduce the charging current (A) until the battery reaches 4.2V volt (V). When the battery voltage is 4.2V, the battery is full and the charger stops charging.

The charger keeps batteries above 4.1 V fully charged. If you want to fully charge this type of battery, you must insert it into the charger before plugging in the charger. All batteries discharge with time naturally on their own. If the batteries are stored in the charger, charging starts when the battery voltage drops below 4.1 volts.

The Xtar D4 is also capable of charging deeply discharged battery cells. Batteries with a drip to zero can be revived with Xtar chargers. The charger detects the deep discharged battery and starts it to wake up automatically. Please note! Disassembling the battery cells too empty may break the battery, and resuscitation may not be possible. Using Li-ion batteries empty reduces their capacity and service life or may render the battery completely unusable. Avoid disassembling the batteries too empty! 

If your device does not have electronics to protect the batteries from deep discharge (e.g. flashlights), see the protective circuit batteries here: https:// proakku .en/product compartment/batteries/batteries protection circuit/

The Xtar D4 battery charger also takes into account the critical warming of the battery life. Too hot temperature reduces battery capacity. The Xtar D4 charger's power supply is separate from the charger, so it doesn't heat rechargeable batteries for nothing! Together with separate power supply and heat transfer design, Xtar promises rechargeable batteries to heat up to 15°C.

Summary:

This charger is only for Li-ion cell, it can charge fairly fast, but will adjust charging speed depending on cells. The user interface is very simple: cell for fast charging goes in the outside slots, other cells in the centre slots.

I will rate this charger fairly good.
