Exell A177 Alkaline 10.5V Battery PC177A, EN177A, TR-177
Exell A177 Alkaline Battery is an alternative for the once-popular Mercuric Oxide 7MR9 and H-7D batteries. It is a little slimmer and a little shorter in length than a standard AA battery. It is the perfect replacement for the hard-to-find Duracell PC177A and Energizer EN177A, and it fits several Sony long shotgun-type condenser microphones. This A177 replacement produces 10.5 Volts, which is higher than the 9.45V and 9.8V produced by the original mercury version. Most devices accommodate the small increase in voltage and function perfectly.
