Dad had bought this detector new in 1986 (I still have the receipt), and I know he used it often, as he was a dedicated MD'er. I kept the detector because I wanted to use it, mostly because it was his, but they're still supposed to be a good detector to this day.
Anyway, I noticed the battery holders were distorted and cracking on the bottoms, due to their design. I'd found a conversation via internet search regarding replacements. I'd seen them from a large MD retailer for $5/each plus shipping, but also saw them in the prior mentioned conversation at SurplusSales for $2/each plus shipping.

Just so happened I had a couple power supplies damaged by lightning last week, so I ordered them, as well as a pair of the battery holders. I will update once they arrive (Monday) as far as fitment.
In the meanwhile, I epoxied a small scrap piece of Kydex to the bottom of each battery holder, and once it hardened, put them on the belt sander. They both fit back into the machine just fine, and can serve as spares once the new ones arrive (and fit properly).
Red arrow points at the gap, which lets the spring-loaded batteries cause pressure on the "flap" which is the bottom, causing it to bend downward. It was also beginning to crack the plastic. You can see the additional material (white) I epoxied to the bottom, and let cure while lightly being clamped.
