Introduction |
| If you have an old or newly acquired Maxxum 5000/7000/9000 and notice battery corrosion, this guide will show you how to clean the corrosion. | | | === ***GUIDE NOTES*** === | | * ***THIS GUIDE ONLY COVERS THE AAA COVER, AS THE DISASSEMBLY PROCEDURE IS UNIQUE.*** | | ** ***''AA covers do not need to be disassembled. The corrosion can be cleaned without disassembly.''*** | | * ***The nickel plating will be stained or stripped. There is no way to fix this without a nickel replate.*** The cover can be cleaned without neutralization to reduce the damage first, but cannot be avoided. ***If*** ***the corrosion is left untreated, it may ruin the cover beyond repair!*** | | * ***IF THE ALKALINE SITS TOO LONG, IT CAN DAMAGE THE COVER BEYOND REPAIR, ESPECIALLY THE THIN CONTACTS EMBEDDED IN THE SCREW PLATE. If there is corossion on the screw plate tabs, these may require light sanding.*** ***If the camera still does not turn on, the cover must be replaced.*** | | === ***Battery replacement options*** === | | If your original AAA cover is unrepairable, there are a few Lithium options which are recommended over Alkaline. | | | * ***2CR5:*** ***Primarily used in film cameras(+some early digital), and some binoculars.*** ***''You will need to buy these online, or from a camera shop with regular film customers.'' Generally speaking, retail availability is poor. Check your area first.*** | | ** ***''While most big box retailers only sell online only, some Best Buys may have a handful in stock in-store as well. However, they cost way too much.''*** | | ** ***''While you may get lucky at drug stores (Walgreens, CVS, RiteAid, etc), DO NOT rely on this. Drug store customers primarily use digital cameras. Drug stores destroy negatives.''*** | * ***CR123: Commonly used in gun scopes, binoculars and distance calculators, plus high draw devices. Not cheap, but easier to find especially in bulk. Performance will be similar to 2CR5, as the 2CR5 is 2x123 cells welded together. Not common on later Minoltas, but was a lateran option in the beginning.*** | | * ***CR2: Another common gun scope and distance calculator battery also used in high draw devices. These are also easy to find, but less common then CR123. ''These are sometimes found in later Minolta cameras like the Maxxum 5 and QTsi/STsi, but none of the older ones.'' These can largely be ignored.*** | | === NOT RECOMMENDED === | | * ''Budget: Like-for-like AA or AAA battery cover. Use Primary Lithium or NiMh. Beyond 10 packs, this is too expensive, and conversion is more cost effective.'' | | ** ''***NOTE:*** ***Runtime will be less than what a specialized battery provides, but this is the cheap(er) way to prevent the issue from coming back. While not as good, these are sold everywhere.***'' |
