I have a MB16 battery replacement for my Nikon N-80

Replacing the Batteries

• Open front cover and locate the battery compartment door.
• Gently remove the two "AA" alkaline batteries located in the battery compartment.
• Install two new "AA" alkaline batteries into battery compartment. Make sure to match the positive (+) ends of the batteries with the positive (+) terminals located in the battery compartment.
• Close battery compartment. The low battery indicator should not appear in the display.

I think the extent of the instructions is on the Nikon USA web site. Here it is

"The Nikon MB-40 Multi-Power Battery Pack accommodates eight AA (alkaline, lithium, or Ni-MH) batteries, or the Nikon EN-EL4 Rechargeable Li-ion Battery. The MS-40 Battery Holder comes with the MB-40. With the MB-40 attached, film can be advanced as fast as 8 fps.
When using the EN-EL4 battery, the Battery-Chamber Cover BL-3 must be used.
The MB-40 is also a vertical grip, and features a vertical grip shutter release, an AF start button, and Multi-selector and Command Dials for more comfortable and responsive shooting."

To install the batteries:1. With the back of the radio facing you, remove the belt clip (seediagram below) for easy access, then remove the Battery Coverby pressing down on the top center and sliding it down from theradio.2. Insert 4 AA batteries observing the polarity as shown. Installingthe batteries incorrectly will prevent the unit from operating ormay damage the unit.3. Return the Battery Cover by sliding it up on the radio. Replace thebelt clip, making sure it locks into place.

Good quality rechargeable batteries are a must for these cameras. What I would suggest is AA' NI-MH rechargeable batteries the type that come already charged and when used and recharged will hold their charge up to 80% for a year. These batteries you will find will outlast any AA Alkaline type. If you are using a no name department store AA Alkaline type battery it's a wonder it even turned on.

If you are referencing the added grip, MB-16, you may use rechargeable AA batteries, or other regular AA batteries. My preference is rechargeable.

Remove the 2 screws on the back and remove the back cover. This will allow you to access the inner cover that has 3 screws. Remove those screws and take off the inner back cover to access the battery. Be sure to read the NOTE concerning installation on that page
You will find the battery at shaveroutlet.com. See link below

Hi darciegracem, Does this happen with the MB-16 battery pack using AA batteries? If so clean the contacts on the battery pack and inside the camera. Make sure it is screwed snug to the camera. If it happen when using the two 123 batteries as well, it may need a trip to Nikon. These cameras go used for about $100 or less thus, you may not want it repaired but, rather purchase a used one from a reputable dealer. The F80/N80 is a very nice camera.

1) Have you formatted the cards?

2) Try the cards in the card reader in your computer to see if they can be read.

3) Try the "switch off camera - remove and replace battery - switch on camera" trick with the original 128 Mb card in place. This will reset the camera's memory.

4) Note the type of card is important - not all cards can be used in a camera (especially some of the latest bigger ones) - check the type of cards supported by your camera.

I found this at the Nikon USA site (note that the 2 GB card is not listed - as said "Cards are not all the same" and use different drivers to operate them):

Question Which Secure Digital Cards are approved for use in the Coolpix 4600/5600? Answer The Nikon Quality Department has tested the following cards and approved their use in the Coolpix 4600/5600:

SD memory cards:
SanDisk 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 256 MB*, 512 MB, 512MB*, 1 GB
Panasonic 16 MB, 32 MB, 64 MB, 128 MB, 256 MB*, 512 MB*,1 GB
Toshiba 16 MB, 32 MB, 64 MB, 128 MB, 128 MB*, 256 MB, 256 MB*, 512 MB

*High speed type of 10 MB/s or over

Other brands and capacities of cards may work, but Nikon cannot guarantee their operation. Check with the manufacturer of the third-
party card for compatibility information. Nikon recommends keeping one of the approved cards available for troubleshooting.

To quote Nikon. 'hold the camera's battery chamber cover at approximately 45 degrees to the camera body and then pull it out gently'.
