Terry,
They probably would work, but it costs US $21.83 shipped.
For US $22.50 shipped you could get basically the same thing, with KNOWN quality from CPF member AW. EDIT: I forgot to add in shipping of the batteries to the total, 13.50 DSD + 4.50 x2 + 4.50 shipping = US $27.00 Sorry!

If the link doesn't work, go to the Dealer's Corner, thread is titled, "AW's LiIon Batteries Sales Thread"
[[ EDIT: US $27.00 ]] is for one (1) DSD charger with charging spacers for 14500's [US $13.50 shipped] and two (2) UNprotected 14500's [US $4.50 each x2 + US $4.50 shipping for up to six (6) batteries]. He also has protected 14500's for US $9.00 each if you prefer.
Protected vs. UNprotected...from what I have gathered reading threads...SEE NOTE AT END OF POST
Unprotected are actually a hair shorter than regular AAs and will have no problem fitting. They still have PTC built-in for thermal protection.
Protected are as much as a couple-three mm's longer than regular AAs and have built in overcharge & overdischarge protection. They sacrifice some capacity to do this and are also thicker than regular AAs. They may not all fit.
The DSD is a smart charger that prevents overcharging. So with thermal & overcharge protection covered, the only difference left is overdischarge. Being a single celled application there is no risk of reverse charging and subsequent (sp?) 'venting with flame'. Overdischarging a single cell ONLY results in damage to the cell - NOT 'venting with flame'. As long as you pay attention and charge the battery when it drops in output, there is no problem using them.
NOTE: I am NOT a battery expert. Check for yourself if what I have said is correct. I assume no liability. If someone more knowledgable reads this, please correct anything I have wrong.
