bought the fenix l2d light last year, have not used it much. Maybe a run time of 3 hours. My issuse is that I pulled out the pre charged -rechargable batteries , charged them up then put them back into the light and now it does not turn back on. I did try another set of rechargable batteries and they did not work ether. I di not not try some dispossable one. any ideas...please thanks
