What is the refresh button for?
The refresh button will completely discharge the battery, then charge it back to full capacity. Doing this regularly can help extend the lifespan of your nickel metal hydride or nickel cadmium batteries.
When should I use the “refresh” button?
Use this feature on batteries that have been unused for a long period of time, such as every 2 to 6 months periods.
Do I have to charge 16 batteries all at once?
No, you don’t have to charge 16 batteries at once. The Tenergy TN348 charger has individual charging slots, which means that you can charge as few as 1 battery or as many batteries as you need to.
How long does it take to charge the batteries?
Charge time can vary depending on the battery. An estimated charge time = battery capacity (mAh) / charging current (mA) x 1.3 (which is an estimation of the charging efficiency for this charger)
How do I know if the battery is full?
Once the battery is fully charged, the bar level on the battery icon on the LCD screen will be solid and stop flashing.
