MetalRobotHead Posted July 18, 2009 Share Posted July 18, 2009 We all know about the problem of new alkaline batteries being a bit too lively and heavy for our old robots, either blowing the bulbs filaments apart, toppling the robot over due to the weight or having plenty of AA's and no D's. One solution might be these AA to D cell converters that are available in all sorts of colours and styles, anyboby any experience of using them? :unsure: Link to comment Share on other sites More sharing options...
funkrobotik Posted July 18, 2009 Share Posted July 18, 2009 Didn't even know they existed MRH.Looks like a great idea though especially for the Space Conkers as they do have a built in desire to fall over backwards. Link to comment Share on other sites More sharing options...
Sonny Young Posted July 18, 2009 Share Posted July 18, 2009 Yes, they work as advertised, allowing you to use alkaline cells without all the weight. I use the one piece units that don't have a cover. The AA slips in and you are ready to roll. Radio shack sells them, and of course, you can find them on ebay. Very inexpensive. Link to comment Share on other sites More sharing options...
Electric Robot and Son Posted July 18, 2009 Share Posted July 18, 2009 The ones I have are stacked AA to C to D, like the wooden eggs. I have used the C to D ones and the AA to C. They do lighten the weight. They also work well in toys where the batteries are loaded in tubes. I have several 50's space rifles where the plastic has shrunk or warped and the D cells don't fit anymore and I have used the C to D adapters for those. These have been around for a while. I used them to adapt battery op robots for my son about 15 years ago. I attached wires to the adapter terminals and brought them out of the battery box to a remote control box with batteries.

My Thunder Robots keep falling back and with less weight this will work out great. Link to comment Share on other sites More sharing options...
Roboto Posted July 18, 2009 Share Posted July 18, 2009 This is great I just did a weight check one D cell alkaline is 5 1/2 oz. Two AA cells weight is only 2 oz what a big difference. :)They are available online only from the Shack.http://www.radioshack.com/search/index.jsp...dapter&sr=1 Link to comment Share on other sites More sharing options...
Electric Robot and Son Posted July 20, 2009 Share Posted July 20, 2009 I used to find these at dollar stores and surplus stores. Link to comment Share on other sites More sharing options...
Roboto Posted July 24, 2009 Share Posted July 24, 2009 The converters arrived today and off they went into my Thunder robots and away they went running great and NOT falling back. They also ran great in the space evils with less weight in the body as they did the roto-turn.Thanks again MetalRobotHead for starting this post. I did have to use a thin washer for one side only for the contact on the minus side. :) Link to comment Share on other sites More sharing options...
Roboto Posted September 25, 2010 Share Posted September 25, 2010 I JUST ORDERED A SET (4) AT RADIOSHACK $9.99, HAD TO ORDER NOT A STOCK ITEM, THIS MAY WORK FOR ME. Just remember for all smoking robots you still need the D ones to get a great smoking action going. :) Link to comment Share on other sites More sharing options...
RobotB9 Posted April 25, 2012 Share Posted April 25, 2012 I JUST ORDERED A SET (4) AT RADIOSHACK $9.99, HAD TO ORDER NOT A STOCK ITEM, THIS MAY WORK FOR ME. Looks like the Radio Shack still has them and also for "C" cells, a pack of four for $6.99 http://www.radioshack.com/product/index.jsp?productId=3402580 Link to comment Share on other sites More sharing options...
Racerxc70 Posted May 8, 2013 Share Posted May 8, 2013 I highly recommend these from Sanyo, the AA's are locked into place when you slide them in and the back end is open assuring full contact, they work great. They also come in C and AAA sizes. Link to comment Share on other sites More sharing options...
