Is my Sanyo eneloop charger NC-MQN04E faulty?

I have 3 sets of (4 AA) Eneloop batteries and the Sanyo MQN04E charger that came with the set.

The eneloops are of 1.2V, Min. 1900 mAh and the charger output is 2.4V, 250mA x 2(AA).

The problem is with the LED which always shows green. Even after plugging it for 2 days it shows green and there is no way to know if the batteries are charged or not.

Is the charger faulty? Should I change it?
How long does it take for this charged to recharge 4 AA eneloops which are completely depleted?

The charger that you have will only charge in pairs of batteries. A better charger will charge each battery individually. Maha, and others make such a charger. The manual that came with the charger will state the charging times. Google - Sanyo Eneloop charger NC-MQN04E - to find a PDF manual online. Have to tested the voltage of each cell after charging?

My recommendation is to get a better charger that has individual circuitry; it is worth the money and less frustration. Also, your rechargeable batteries may run longer without hassle.

I don't know what model number my Sanyo Eneloop charger is, but it seemed like it was defective. With all four batteries in only one green led would light. It would blink all the time. Also I was getting very quick yellow battery indication on my K-r. Yesterday I charged the Eneloops with an Eveready charger and so far so good.

If this is of any help, my charger behaves exactly the same. However, after approx. 12 hours, the green lights disappear, so I believe they are meant to be green while the batteries are charging.

Thank you. It seems my charger might be defective after all. Need to buy a good one.
