Actually,

I ordered a pair of these batteries with the tabs. The tabs thickness measures 0.02 mm, and these tabs, as they are on my batteries should not interfere with the charger at all. Unless I am missing something?

I don't know what charger you ordered so I can't say if those tabbed batteries will 'fit'.

The charger I linked to would be used with a pair of alligator clips (Red & Black) so you would simply clip to the tabs for charging rather than trying to 'fit' the battery into a charger.

  Abe,
  
  I think that I may order your suggestion as well. Who knows when or if my D4 charger will ever show up.
  
  Thanks

    Chopper...nobody here seems to have addressed the real question here--why do you think you need a trickle charger on the lithium cells in the first place? Lithiums have about the lowest self-discharge of any of the cell chemistries out there. A charged lithium battery can sit on the shelf for a long time before you get significant voltage drop.
    
    Leave a well designed Li charger hooked up to the battery. It will come on when the battery needs charging, and be invisible to the circuit when not charging. It's all you need. I've designed many kinds of commercial portable equipment this way, and it's pretty foolproof...

      Adam,
      
      You are absolutely correct with your point. I think that I will do just as you suggested and drop the "Trickle Charger" hunt.
      
      Thanks,

      it's probably about 3% a month, at worst.
      
      The problem that I see is doing both at the same time: powering the Regen and then seeing the voltage drop to the point where the charger needs to kick in.
      
      I don't know if it's kosher to drain a cell AND charge it back up at the same time, hence my recommendation of a battery cradle and spares.

        Chris I like that idea a lot. The other challenge with leaving the charger connected in an audio application is that you might well be introducing noise from the charger...not a problem in the optical particle counters that I design, but definitely something to consider here...
        
        You obviously have a more in depth knowledge than I about this stuff... - Chris Garrett 11:49:53 12/04/15 (0)

        but I have learned a lot from people like you hanging out on the flashlight forums, where we use li-ion all of the time and sometimes upwards of 10A-15A per cell.
        
        We're now taking a back seat to the E-Cig guys and their 'sub-ohm' builds, where they can place 20A+ loads on single 18650s, but it's a neat 'hobby within a hobby.'
        
        I actually like talking about the batteries, cells and chargers more than the lights, lol.
