Charging Rechargeable Batteries
• Do not mix batteries with different amounts of charge remaining, or batteries of a different make or model. • When using EN-MH2 batteries with the COOLPIX L610, charge two batteries at a time using Battery Charger MH-72. When using Battery Charger MH-73, charge two or four batteries at a time. Use only Battery Charger MH-72 or MH-73 to charge EN-MH2 batteries. • When using Battery Charger MH-72 or MH-73, only charge EN-MH2 batteries.
Notes About EN-MH1 Rechargeable Batteries and Battery Charger MH-70/71
You can also use EN-MH1 Ni-MH rechargeable batteries with this camera. Use only Battery Charger MH-70 or MH-71 to charge EN-MH1 batteries. When using Battery Charger MH-70 or MH-71, only charge EN-MH1 batteries. Set Battery type (A 99, E92) to COOLPIX (Ni-MH).
Notes About Rechargeable Ni-MH Batteries
• If you repeatedly charge rechargeable Ni-MH batteries while they still have some charge remaining, the message Battery exhausted. may be displayed prematurely when using the batteries. This is due to the "memory effect," in which the amount of charge the batteries can hold decreases temporarily. Use the batteries until there is no charge remaining and they will return to their normal behavior. • Rechargeable Ni-MH batteries discharge even when not being used. We recommend charging the batteries just before using them.
Technical Notes and Index
Cold Environment Usage
Battery performance decreases in cold environments. When using the camera in cold environments, try not to let the camera and batteries become too cold. The camera may not function if you use discharged batteries in cold environments. Keep spare batteries warm and alternate between two sets of batteries. Batteries that cannot be used because they have become too cold can often be used again when they have been warmed up.
Dirt on the battery terminals can prevent the camera from functioning. Remove dirt from the terminals using a dry cloth.
