How We Test Rechargeable Battery Chargers

There are so many battery chargers on the market. Smart charger, trickle charger, or even a basic charger with fewer features and a much cheaper price. The most important factors to consider when buying a new battery charger:
1. Indicator to show when the battery is charging or fully charged. This is important to60% of battery charger owners.
2. How many different sizes of batteries it can charge. More than half (51%) found this important.
3. Trickle-charge function. Useful especially if your batteries are small-capacity cells, and the key to 45% of people we surveyed.
4. The speed at which the battery charger claims to charge is important to 23% of those we surveyed. Bear in mind that higher-capacity batteries take longer to charge.
5. As the maximum charge, a rechargeable battery can achieve decreases over time, many people thought it was useful to choose a charger that shows you how much capacity remains.

Whether it’s your first time buying a charger or you’re replacing an old one, it’s worth knowing what extra features are worth paying for, including the charger quality. As a professional battery charger manufacturer, XTAR exposed its charger product testing process for the first time. Let’s see how we test our battery chargers.

1. Over ten tests for chargers’ appearance

2. Accurate testing for judging battery voltage after fully charged with professional equipment, keeping the performance parameter deviation within 1%.

3. Aging test. Simulating the daily use of battery chargers, testing the stability of electronic components. Test duration: 1-10 hours.

4. Extreme high-temperature tests to ensure the chargers use safety in extreme environments. Test duration: 1-5 hours. Test temperature: -20℃-65℃.

5. Button press test. Check the service life of the buttons on the chargers and eliminate the bad buttons of the products. Test duration: 1-5 hours, test times: 2000-50,000 times.

6. Interface plug detection. Ensure that the product keys are used more than 2000 times. Test duration: 1-5 hours, test times: 2000-50000 times.

7. Anti-drop test. Simulate the battery charger’s daily use environment and test the durability of the housing.

The product quality inspection in XTAR is full inspection.

As the first eight-slot charger in the history of XTAR that supports lithium-ion, NiMH, and NiCd cells. The XTAR VC8 uses a USB-C input current for faster recharge of all the batteries, this current can be changed manually in 3A, 2A, 1A, 0.5A or 0.25A, which allows the user to adapt the various currents to the needs of your batteries.

The charger has two displays and four buttons. It is two partly identical sections.
Button Mode/Disp.: This selects between current, capacity, and IR display, hold down to select grade and store function (Only first section).
Button Curr.: Selects maximum charge current, Automatically detects battery type and selects the best charging strategy

Additional Features:
1. Support QC3.0 fast charging, max 3A for a single slot
2. Charge 8Pcs Protected 21700 Simultaneously
3. In grading mode, the charger tests batteries’ real capacity, so that users can know whether the battery capacity is overstated or not.
4. The charger can charge or discharge the battery to it’s rated voltage in storing mode
5. The charger will automatically identify the battery type, to select the most suitable charging method, so that users don’t need to select manually.
6. The built-in real-time temperature control protection system makes the battery charging process more stable.
7. Passed many international safety and quality certifications, such as RoHS, CE, FCC

Let’s see how Vic think of this charger

To sum up, the XTAR VC8 eight-slot multi-function charger is different from traditional eight-slot chargers on the market. Use a type C port to support QC3.0 fast charge and maximum 3A charging speed. XTAR VC8 also automatically detects the status of the individual cell and then supplies the battery with the appropriate current.

In daily use, all the common lithium batteries can be installed, from 16340 to 26650. If you have many flashlights or need to use many batteries, this VC8 charger will bring you convenience.
