How long should I charge NiMH batteries in my Nexcell NC-15SC charger?

The NC-15SC charger will charge NiMH batteries at a constant rate 150mA for AA and 50mA for AAA and then shut off with a timer at 15 hours. As long as your AA or AAA NiMH batteries are mostly discharged you can leave them in for the full 15 hours. If you are just topping off a previous charge you should remove the batteries after you have estimated a complete charge. Unplugging the charger or a power interruption will start the timer over again. See the FAQ above for the MH-124S for guidance on how to estimate charge times.

How do I know how long to charge my batteries?

All of our battery chargers are automatic. Follow the charging instructions that came with your charger. For most battery chargers with LED lights the RED light on indicates charging in progress and the GREEN light on indicates charging completed. You can also calculate the approximate charge time using this method. Divide the desired charge mAh by the charge rate of your battery charger mA. For example to charge 1600 mAh rated batteries that are fully discharged it would take about 2 hours using a charger with a charge rate of 850 mA. (1600/850 = 1.88 hrs.)
