I did not use low self discharge cells in my Dinotte because I dropped the NiMH into the light straight out of the charger, so self discharge never was an issue anyway. No reason they shouldn't work though.

The funny thing is, the only difference between normal and LSD NiHH is a wrap of blotter paper soaked in de-ionized water wrapped around one electrode. Probably costs a tenth of a cent, but they sure charge for it at retail.
