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. The AA cover can be cleaned without disassembly, outtside of severe corrosion issues where it may have went on the hidden portion of the terminals.*** | | * ***READ: YOU WILL LOSE SOME OF THE NICKEL COATING -- NO WAY AROUND IT! Do not skip proper treatment to avoid this; residual alkaline can cause further problems or permanent damage, especially the screw plate contact strips.*** | | === ***Battery replacement options*** === | | If your original cover is unrepairable, the recommended fix is to switch to the 2CR5 cover (BH-70T), if possible. ***However, the required battery is not readily available in most retail stores. It may be possible to find these at CVS or Best Buy* (and some local "regional" chains), but retail availability today is poor.*** | | | ``***''*Check in advance. Some do, some don't - especially CVS.''***`` | | | ***The retail availability was somewhat maintained for a long time due to common use in gun scopes, binoculars and distance calculators (as well as film/early digital cameras), so you could buy them from places like Cabella's or Bass Pro Shops for a long time. However, the CR123 became the "standard" battery, which made them even harder to find outside of camera stores and the internet.*** | | | ***''You will most likely need to stock up, check nearby camera stores or 3D print a 2CR5 adapter which takes the CR123 batteries.''*** | | ``***''Nonstandard namenames note: some manufacturers use terms like CR123A, DL123 (Duracell) or SF123A**, and other terms not listed.''***`` | | | ``***''**(Surefire, flashlight manufacturer). MAY NEED TO REMOVE WASHER UNDER THE NEGATIVE TAB HIDDEN BY THE LABEL.''***`` | | | === NOT RECOMMENDED === | | * ''1.5V primary Lithium. ***Will not leak and easy to find, poor economics and mediocre runtime compared to 2x 3V cells (CR123) or a 2CR5.***'' | | ** ''(AA/BH-70L)/(AAA/BH-70S).'' |
