Q: Do you have a video on how to use the charger?
Q: Can I charge my AA, AAA, C, and D batteries at the same time?
A: Yes, you can charge different size batteries at the same time.
Q: Can I insert more than 1 battery in a slot?
A: No, you can only insert 1 battery per slot.
Q: How long will it take for my batteries to charge?
A: Charging time varies depending on the battery size and the charging mode you use. Please see the mode and battery size below.
- Rapid Charge Mode (Default):
- AA (2600mAh): 1-1.5 hours
- AAA (1000mAh): 1 hours
- C (5000mAh): 2.5 hours
- D (10,000mAh): 5 hours
- Soft Charge Mode:
- AA (2600mAh): 2-3 hours
- AAA (1000mAh): 2 hours
- C (5000mAh): 5 hours
- D (10,000mAh): 10 hours
Q: Can I leave my batteries in the charger?
A: You can leave your batteries in the charger once they are done charging and don't have to take them out right away. However, we DO NOT recommend storing your batteries in the charger. You can use a battery holder to store your batteries.
Q: What happens if I insert my battery in the charger backwards? Will it damage the charger or battery?
A: The charger will not charge that slot and will display a flashing DONE on that particular slot. This indicates there is a Battery Fault.
Q: Can I use other brand batteries in the charger?
A: Yes, as long as they are NiMH rechargeable batteries. However, we always recommend using Powerex batteries for best performance.
Q: What does it mean if the charger doesn't recognize my battery?
A: It means the battery is bad. But first, make sure the battery is properly seated. Insert the battery so that the negative end touches the charging contacts first, then tilt it forward until it clicks. You can also try removing the battery and inserting it into another slot. If the battery still can't be recognized, it might no longer accept charge and should be replaced.
Q: When do I use the Soft Charge Mode?
A: The Soft Charge Mode is used when charging time is not critical. We always recommend charging at a slower rate whenever possible. It maximizes the battery's life and its performance.
Q: Is it normal for the batteries to get warm when they are done charging?
A: When charging is almost done, the batteries may get a bit warm to touch. The battery temperature will quickly drop after charging is done. Also, older batteries or batteries in poor health may get hotter after charging.
Q: Why is the LCD display faint?
A: Be sure to remove the protective sticker on top of the LCD. Like other LCDs, the display shows the highest contrast when viewed from a certain angle. Viewing the LCD from a lower angle will yield better clarity.
Q: Why does the charger make a faint clicking sound?
A: This is pulse charging at work and it is normal.
Q: What is the difference between a solid "DONE" and a flashing "DONE"?
A: A solid "DONE" indicates a battery is done charging and will be displayed for each slot that is done charging. A flashing "DONE" indicates there's a Battery Fault and your battery is bad, so charging for that slot was terminated by high voltage. It is common for certain NiCD batteries to terminate this way and does not harm the health of the battery. It could also indicate there's an alkaline battery in that slot.
Q: Why is it recommended for the batteries to be inserted from left to right?
A: The right portion of the charger produces slightly more heat than the left. While this heat does not affect battery charging, it is recommended as a "best-practice" to occupy the left banks first.
Q: When should I condition my batteries?
A: We recommend conditioning your batteries every 6 months or once a year.
Q: In the Conditioning Mode, why do the batteries appear to charge for a very long period of time?
A: During discharge (second phase of the conditioning mode), batteries that are finished before others will show the charging symbols. However, actual charging will not commence until all batteries have finished discharging. Therefore, the charging symbols shown along discharge symbols indicate they are standing-by for charging. This is designed to allow a rest period between battery discharging and charging, thereby improving battery performance.
Q: In the Conditioning Mode, during discharging, the right side of the charger becomes warm. Is this normal?
A: Yes, it's normal. The energy drained from the batteries is dissipated as heat. The circuit is located at the right side of the charger.
Q: Why can’t I charge lower capacity batteries?
A: The batteries, not the charger, determine if they can be rapid charged. You can check the specification of the batteries to see if they can accept the charging current listed in the manual. However (and quite often), when the maximum charging current is not specified, it is safe the use the following rule of thumb: For normal charging mode (Rapid): AAA capacity greater than 700mAh, all others greater than 2000mAh. For Soft charging mode: AAA capacity greater than 350mAh, all others greater than 1000mAh.
