Titanium Innovations 3 x AA to 1 x D Serial Battery Adapter

These battery canisters put three AA-sized batteries in series taking the space of a single D cell. Commonly used with rechargeable Ni-MH batteries, this allows greater overall voltage in applications using D cell.

Upgrade your 2-D Maglite by first selecting a TerraLUX upgrade suitable for 6D Mags, then use two of these battery canisters with rechargeable Ni-MH AA's to put the needed 6 cells in series.

Better than a sealed battery pack!
April 23, 2017
I had 3.6V NiMh battery pack with 3 batteries in a triangle shape within my wine opener. The battery packs were expensive and had a set milliamp hour figure. I found this battery adapter that fit 3AA 1.2V NiMh cells just like the battery pack equaling the 3.6V I needed in this series configuration. The ends of this adapter we're very easy to solder my wires to. I used a little rubbing alcohol on the ends before I soldered for a strong clean connection. Now I have a way to replace batteries whenever I want! If my wine opener ever dies I'm going to keep my adapter!
  • Well made, perfect size, easy to solder ends, versitile.

Good quality,

These are well built devices, but I ordered the wrong part. This puts the AA cells in series, but another version puts them in parallel. Those are the one I wanted. Totally my fault, not Battery Junction. Just understand there are two versions. I was able to convert these to parallel, but it took a soldering iron and some work.
  • High quality
  • You can store your flashlight with rechargeable batteries to protect it from alkaline leaks. Then switch to D cell alkaline when you need it for long term use.
  • Be aware that there are two versions. Get the one you need.

While I cannot vouch for long-term durability at this point, I can state that these adapters are easy to load and unload and work perfectly!
  • They Work!

Awesome!! Turned my 2-D Mag into a high powered 1000 lumen torch with the Terralux 310M-EX drop in. Nice for emergency & short time use...

I have used the cheap 3 AA converters and these are worth the extra money for sure. Batteries fit snugly all connections are tight. I am using them in a mag. 2d ROP
  • Also have to mention battery junctions fast shipping and never an issue with any products I have purchased from them
