Introduction |
| If you have an old or newly acquired Maxxum 5000/7000 with battery corrosion, this guide will show you how to clean it. | | | === ***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 existing nickel plating will be stained or stripped. There is no way around this without replating.*** The cover can be cleaned without neutralization to reduce the damage first,first this but ***''but cannot be entirely avoided as it can. Improper treatment may cause unrepairable damage if improperly treated!''***. | * ***''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 corossioncorrosion on the screw plate tabs, theselight sanding may require light sandingbe required (potentially a new cover).*** ***If the camera still does not turn on, the cover must be replaced.*** | | === ***Battery replacement options*** === | | If your original cover is unrepairable, there are a few Lithium options which are recommended over Alkaline. | | * ***2CR5:*** ***Primarily used in film cameras, some early digitaldigitals, and binoculars.*** ***''You will need to buy these online in most cases, or from a camera shop with regular film customers.'' GeneralCheck in advance/plan ahead, poor general retail availability is poor; check before the photo shoot.*** | ** ***''While most big box retailers only sell online only, someSome Best Buys may have a handful available in-store. However, theybut at a higher cost way too much.''*** | ** ***''NOTE: While you may get lucky at drug stores (Walgreens, CVS, RiteAid, etc), DO NOT rely on this.RELY ON STOCK LEVELS.Drug store customers primarily use digital cameras. Drug stores destroy negatives''*** | * ***CR123: Commonly used in gun scopes, binoculars and, distance calculators, plus and high draw devices. Not cheapWhen used as a set of 2, but easier to find especially in bulk. Performanceperformance will be similar to 2CR5, as the1x 2CR5 is 2x123(same cells welded together). Good retail availability, pricey when purchased at retail.*** | * ***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 the CR123. ''These are sometimesSometimes found in later Minolta cameras like the Maxxum 5 and QTsi/STsi, but none of the older ones.'' These can be largely ignored hereIgnore these unless you have one of these Minoltas, or a compatible cover.*** | | === 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.***'' | | * ''1.5V primary Lithium (AA/AAA) cells. Less runtime than a specialized cell, like a CR123/2CR5. ***NOT ECONOMICAL IN SMALL PACKS, OR BEYOND 10/PACK. These only have one advantage: availability.***'' |
