• Once charging is complete, remove the batteries from the battery charger.
• Remove the power cable from the power outlet when not in use.

Precautions for Use (Nikon EN-MH1 Rechargeable Ni-MH Batteries)

• These batteries are for use exclusively with Nikon COOLPIX 3100 and 2100 cameras.
• Rechargeable batteries may require frequent recharging immediately after purchase or after being left unused for an extended period. This is characteristic of this type of battery, and the batteries will charge fully after being recharged a few times.
• For best performance, charge batteries at an ambient temperature of 18 –30°C (64 – 86°F).
• Always charge both batteries at the same time.
• If you are using more than one pair of EN-MH1 batteries, identify the batteries in each pair by marking them where shown in Figure 2 (A) to
  avoid mixing batteries with different charges.
  
• Do not use batteries if the outer casing is peeling.
• The internal temperature of the batteries may rise while the batteries are in use. If you attempt to recharge the batteries while the internal temperature is elevated, the batteries will not charge or will charge only partially. Wait for the batteries to cool before charging.
• You may notice radio or television interference when charging batteries. Keep the charger away from radio and television receivers during charging.
• Do not attempt to recharge fully-charged batteries. Failure to observe this precaution will result in reduced battery performance.
• If you shake the MH-70 Battery Charger or touch the batteries during charging, the resulting vibration or static electricity may in very rare instances cause the MH-70 to indicate that charging is complete although the batteries are in fact not yet fully charged. Should this occur, remove the batteries and re-insert them into the MH-70 to continue charging.
• When storing the batteries for extended periods, take them out about once a year, charge them fully, and then use them until no charge remains. You can then return the batteries to storage.
• Charging Ni-MH batteries that have not been fully discharged may result in a "memory" effect, causing the batteries to lose their charge quickly. The batteries will return to normal after being fully discharged and recharged.
• Batteries that retain a charge for only short periods after recharging have reached the end of their working life and can no longer be used.
