Get the Batteries America back for AA cells instead. The pack holds 6 AA MNiH 
rechargeables.  Or if you need extended runtime in the field without an 
opportunity to recharge, yoiu can put 6 standard AA non-rechargeable alkaline 
or lithium cells.     Then get a couple of cards of 1800 mAH Sanyo Eneloop 
rechargeble MNiH AA's at Costco.     Or get the 2700 mAH Sanyos at Batteries 
America.

The pack is slightly larger front to back than the original and the color 
doesn't quite match (it's black instead of the Kenwood dark silver-grey), but 
you get almost three times the run time of the OEM pack at 1/3rd the cost.

The one disadvantage is that you have to remove the batteries from the pack to 
charge them (i.e. no drop-in charging).  Or perhaps it's an advantage since you 
can't accidentally charge primary cells if you happen to have them in the pack 
instead.

Scroll about halfway down the home page for the compact V-6280//8-cell AA/AAA 
cell charger that will run directly on 12 VDC in the field. It's especially 
nice because it analyzes and charges each cell individually instead in pairs 
like most do.    Then jump to the ham radio page at:

     <http://www.batteriesamerica.com/kenwood1.htm>

and look for the BT-11h case for the TH-D7.
