## Questions & Answers

**Q: Why is the charger blinking?**
A: Probably defective. Mines doesn’t blink.

**Q: Will this disconnect if the batteries are full ?**
A: It shows a different light if batteries are fully charged so I assume yes

**Q: What color does it change to when the batteries are fully charged?**
A: Depending on the battery, the light above the section that the battery is in will turn blue or both lights will turn blue when the battery is fully charged.  I haven’t put 2 batteries in to charge at the same time. I did once and neither light turned blue. I just charge 1 battery at a time.

**Q: Can you charge one battery at a time?**
A: Yes
