Is my Aimpoint Ruined?

So I've been out of shooting for over a decade and just got back. Today I took out this old Aimpoint sight that I have, and I haven't looked at it since like 1999, I believe. It still looks pretty good, but the old batteries seems to have leaked or something, and the leakage is greenish. I used a wrench to unscrew the cap. And now I can't remove the batteries. It seems to have sealed itself in or something. Is this sight ruined? Can I do anything to fix it? It's over 14 years old, so imagine that it's out of date and not worth fixing. Am I right? Should I just donate it to Goodwill?

You might try to determine exactly what kind of battery it is and then research a little to see what substance you could use to clean up the residue. I think white vinegar can be use on alkaline batteries, but not sure about lithium batteries. It’s probably a good idea to be careful when dealing with these various batteries and cleaning materials.

Its probably trashed as the electrolyte has snuk everywhere if the corrosion is that bad!

However, you can try a rescue even with the odds against you.
The electrolyte is usually alkaline in nature so a mild acid will neutralize it, but at the risk of doing additional damage. Be prepared to neutralize the acid after it has neutralized the alkaline using something like baking soda & a distilled water rinse follwed by complete disassembly & drying.

Try mechanical means such as picks & needle nose pliers to remove the corroded in batteries first & be prepared to be dissapointed.

Thank you, gentlemen. I will do as such. I mean, it's old, so I have little to lose.

I had an old Aimpoint that I bought in 1998. In 2001 I ended up moving back to my hometown where all my guns were banned, so I stored them elsewhere for a few years. When I got them out of storage, I had a similar problem; my battery appeared to have corroded against the contact points. I took the battery out, got a wooden dowel and glued some sand paper to the end. I used this to break up the corrosion on the contact points inside the Aimpoint. Then I just blew out all the debris.

But after that the Aimpoint still had problems. It had a bad connection and would turn itself off randomly from recoil. I ended up selling it on eBay several years ago for $180. (Don't worry, I fully disclosed its problems to the buyer; eBay's a good place to sell broken electronics.)

Don't use "sandpaper" to clean contacts. Its way way too abrasive & will rip any plating off in a heartbeat!
An ink eraser on a ballpoint pen is as harsh as you'll ever want to go. Also a thin smear of petroleum jelly (Vaselene) will protect previously damaged contacts while allowing electricity from the battery to pass through.

Yeah, that's probably why it didn't work after I "fixed" it... But I wanted to upgrade and I got $180 bucks for it, so it wasn't a total loss.

Anyone called Aimpoint and asked if they can help? They're not a low-end-fly-by-night company, they might hook you up.
