Refreshing Nikon EN-MH1 Rechargeable NiMH Batteries ( 6, 83)
An MH-71 battery charger and rechargeable EN-MH1 NiMH batteries are provided
with the camera in some regions and are also available as options ( 83). NiMH bat-
teries may suffer a temporary drop in capacity if charged after long periods of disuse or
before being fully discharged. They will return to normal after being refreshed a few
times as described below.
1 Insert both batteries into the charger ( 6).
2 Press the REFRESH button until the REFRESH lamp lights and close the lid. The
REFRESH lamp turns off when the batteries are fully discharged. The batteries can
now be removed or left in the MH-71 to recharge ( 6). Unplug the charger after
removing the batteries.
To resume charging before the batteries are fully discharged, or to refresh the bat-
teries once charging has begun, press the REFRESH button for about two seconds.
Batteries that retain a charge for only short periods after being refreshed have reached
the end of their working life and can no longer be used.
