Can I use Lithium AA cells in the UK4AA or UK4AA eLED light?
Electrically speaking, it is OK to to use Lithium AA cells, such as the Energizer L91 Li/FeS2, in these products. The problem is that Lithium batteries are not rated for use in the hazardous locations for which the lights were tested. Only Alkaline AA cells by Duracell, Energizer and Rayovac are rated.
