EXELL A32PX The Exell A25PX was made as a replacement for a variety of different cameras. The A25PX is a mercury-free replacement for the once popular Mercuric Oxide PX25 battery cell that was commonly used in cameras. The alkaline A25PX cells produce 4.5 Volts, which is higher than the 4.05V produced by the original mercury PX25 cell. Most devices accommodate the small increase in voltage and function perfectly.
