If you have an old or newly acquired Maxxum 5000/7000 with battery corrosionan alkaline leak, this guide will show you how to clean it. | | | === ***GUIDE NOTES*** === | * ***THIS GUIDE ONLY COVERS THE AAA COVER. The AA cover can be cleaned without disassembly, outside ofunless it has severe corrosion issues where it may have gone on the bottom of the terminalsleakage.*** | | * ***READ: YOU WILL LOSE SOME OF THE NICKEL COATING -- NO WAY AROUND IT!***[br] | | ``***''Do not skip proper treatment to avoid this; residual alkaline can cause further problems, which may be fatal!''***`` | | === ***Battery replacement options*** === | | If your original cover is unrepairable, the 2CR5 cover (BH-70T) completely mitigates the issue by using lithium cells. ***However, the required battery is not readily available in most retail stores. It may be possible to find these at a drug store (CVS/Walgreens/RiteAid/locally owned regional)* or Best Buy**, but availability is (generally) poor.*** | | | ``***''*Check in advance; drug stores tend to focus on "disposable" cameras.''***``[br] | | ``***''**More reliable availability but check prior if possible.''***`` | | ***The retail availability was somewhat maintained due to use in gun scopes, binoculars and distance calculators (as well as film/early digital cameras), so you and could buy them frombe found in places like Cabella's or Bass Pro Shops at one point.
