If the chamber and calibration lamps flash on and off in sequence when no battery is inserted, there is a problem with the charger. If the chamber and calibration lamps flash on and off in sequence when a battery is inserted, a problem has occurred with the bat- tery or charger during charging. Remove the battery, unplug the charger, and take the battery and charger to a Nikon-authorized service representative for inspection.

Nikon Digital SLR cameras have an auto switching (from 100v to 240V 50hz/60hz) battery charger that will work in most countries around the world. A/C adapters have similar characteristics. Always check the specification plate on your other battery chargers or A/C adapters as third party products may not support dual voltage systems. We do not suggest the use of third party battery chargers and A/C adapters with Nikon equipment.
Note that the cord included with the Nikon charger or A/C adapter is designed for 110 volt use only. A power cord suitable for the local power system should be obtained on arrival, most airport shops and computer suppliers will carry these items which are typically used for laptop conmputer power supply connections. Be sure that the new cord you buy fits the Nikon adapter you wish to use it with and that it is rated for the voltage in your new location. While not recommended, a simple plug adapter may be used, but caution should be taken as the cord Nikon supplies is not rated for the higher voltage and may heat or fail.

Question

Can MH-22 discharge a new battery

Can the MH-22 be used to completely discharge a new EN EL 4a ( D3s ) battery, and then recharge it, in order to build up to its full power ?

I have a couple of new batteries which, though fully charged on the MH-22, are being depleted very quickly and will probably only be good for maybe 500 shots, plus miscellaneous DSLR use.

Thanks,
Keith

Sort of yes, push the calibrate button and it will discharge the battery and then recharge, though you dont normally have to do this with new batteries.

Question

Why are "L" and "CAL ON" lights alternately blinking when my battery is inserted into charger?

I just received a refurbished D3 and this is the battery and charger that came with it. I don't know how old either are. I can't get camera to turn on with this battery (its the only I have) so I dont even know if the camera works.
When i first inserted the battery into the charger the 50% light came on (blinking) but after an hour the alternating lights started and it doesnt appear to be charging.

Press the calibration button and let it run its course, it will discharge the battery and then recharge it. If it doesnt recharge then the battery may be at the end of its life cycle.

Nikon does not produce a battery charger that plugs into the car. There may be third party chargers however Nikon cannot speculate on the compatibilities of third party chargers and their batteries.
