| 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*** === |
| * ***You MUST replace all batteries -- NO EXCEPTIONS! One leak means the rest will.*** |
| * ***THIS GUIDE ONLY COVERS THE AAA COVER, AS THE DISASSEMBLY PROCEDURE IS UNIQUE.*** |
| ** ***''AA covers do not need to be disassembled; neutralize without disassembly.''*** |
| * ***The nickel plating will be stained or stripped. There is no way to fix this without a nickel replate.*** It can be cleaned without neutralization first to reduce the damage 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. In some cases, the screw plate may require light sanding.*** ***If the corrosion cannot be fully removed and it prevents electrical contact, the cover must be replaced.*** |
| === ***Battery replacement options*** === |
| In the event that your original AAA cover is unrepairable, there are varying Lithium options which are recommended over Alkaline. |
|
| * ***2CR5:*** ***This is a specialized battery only used in analog cameras (and some early digital).*** ***''You will need to buy these online, or from a camera shop with film customers. Some big box retailers like Walmart sell them online.''*** |
| ** ***''Some Best Buys have a handful in store as well.''*** |
| ** ***''You may also have luck at some drug stores (Walgreens, CVS, RiteAid, etc). However, most drug store customers use digital or their smartphone.''*** |
| *** ***''While these are the better choice, availability can be an issue unless there's a camera shop nearby where you are shooting your camera. Verify or carry 3+1 in camera before using today.''*** |
| * ***CR123: Commonly used in gun scopes, and some distance calculators, as well as other high draw devices. Not cheap, but far easier to find (especially in bulk). Performance will be similar to a 2CR5, as the 2CR5 is 2x123 cells welded together. Not used in most Minoltas; they use the 2CR5.*** |
| * ***CR2: Again, mostly used in gun scopes and distance calculators and other high draw devices. These are also easy to find, but less common then the CR123. While you see these around, most of the items mentioned above use the CR123 battery. Sometimes used in later Minolta cameras like the Maxxum 5 and QTsi and STsi, but none of the older ones (out of the box). Can largely be ignored.*** |
