This website appears to show the same distress light and suggests a workaround that uses regular AA batteries. AA's are similar in size, but just from reading that page, it seems that the BA-1328 have both the positive and negative contacts at one end of the battery, so the trick is to mimic that arrangement. By wrapping the AA in foil so that the foil reaches the positive end of the AA battery, both the positive and negative terminals can make contact when you put them into the light. I assume that you can do something similar with a thin strip of metal, too.

Just make sure that you don't short circuit the battery by letting the positive and negative terminals connect directly. Good luck!
