I need to replace a NB12120, 12V 12Ah SLA battery, with NB (bolt through) terminals. I can find bookoos of 12120 variant batteries but they all have F1 or F2 (spade) terminals.
I need a 12V 12Ah or greater battery with NB terminals on the same end, that's 6" long, 3-13/16" tall, and 3-7/8" wide.
Amazon, eBay, Batteries Plus, Google, have all let me down.
Any other sources? I've seen F connector to NB adapters, but they're a little really thin compared to the original NB connectors on the dead battery.
I'm beginning to think this is a proprietary battery.
I'd go with the adapters. Think of the current draw requirements, resistance of the adapters, etc., and I think you'll be fine with them. I'd prefer to see pics, of course, but just SWAG'ing this, I'd go with the adapters.
In reply to Dr. Hess:
Battery is for a jump start box. The cables attached to the terminals are ~8Ga. Hence my apprehension using the adapters.
Based on the word "Highrate" in your pic I googled "12v 12ah highrate" and came up with this:

In reply to Dr. Hess:
Some google search examples, they all appear to be the same thickness as the male spade part of the adapter.
Yeah, that would be a bit iffy for a high current application. Like, trying to run 100 amps through it for starting, for example. I think 20 amps would probably be OK, especially briefly. Any idea what the actual current through there when you're using it is? 20 or 100?
In reply to Dr. Hess:
The current version of my jump box claims "200 amp surge" and has a 12 AH battery just like mine. However, mine's about 10 years old, and while it looks exactly the same I'm not sure if the specs are the same.
In reply to 1988RedT2:
Thanks, linked on that same page is the version they suggest for jump starters which would be a bit over $55 with their cheapest shipping. At that price point I'm starting to think it's time to just replace the jump box.
The Titanoboa computerized image is from the courtyard at the Natural History Museum at Unversity of Florida. It was a UF scientist who led the team that found the fossils.
This thread went a little sideways, however I thought I'd update it, in hopes of Google's robots finding & archiving it for anyone else with a similar problem.
From 1988RedT2's mastery of Googlefu I was able to find TD12-12A Tempest Deep Cycle AGM, Sealed Lead Acid Rechargeable Battery - 12V 12Ah
While it was more than I wanted to spend, I could find nothing with the same specs any cheaper. Nut & Bolt Terminal SLA batteries this small are as rare as hen's teeth.
That solved the battery issue, however after I installed the new battery, I discovered that the AC to DC transformer/adapter for the jump starter's internal charger was no longer working. This was another challenge, as I could find nothing similar. I began thinking I'd just have to cannibalize a laptop power brick or something. I really didn't want this to be any more ghetto than absolutely necessary, so I crossed my fingers and emailed Schumacher's customer service not really knowing what to expect.
I was pleasantly surprised to a get response in less than 24 hours, with a direct link to where I could buy the exact AC to DC adapter needed.

When it was all said and done though, I spent about 2/3 of the cost repairing mine as it would have to just have bought the new version on Amazon. It was one of those "practical Christmas presents" from Dad over a decade ago, so there's some slight sentimental attachment, silly I know. Now that it's working again I can hopefully get another 10+ years out of it.
Success!
Thanks for the help everyone!
