| 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, outtsideoutside of severe corrosion issues where it may have wentgone on the hidden portionbottom of the terminals.***

``***''Do not skip proper treatment to avoid this; residual alkaline can cause further problems orwhich is permanent damage, especiallyon the screw plate contact strips.contacts!''***`` | | === ***Battery replacement options*** === | If your original cover is unrepairable, the recommended fix is to switch to the 2CR5 cover (BH-70T), if possible 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* (and some local "regional" chains)*, but retail availability today isis (generally) poor.*** | | | ``***''*Check in advance.
