AA batteries are common place in may electrical items throughout homes and businesses.
However, choosing the right manufacturer for high performance pro audio applications such as wireless microphones can be vital.
Rechargeable AA Batteries do not give the full 1.5v output, instead they average at 1.2v. They also have a habit of suddenly going flat without warning, therefore we do not recommend using them in wireless microphones.
As installers and users of wireless microphones we have found that duracell aa batteries continue to outperform all other aa alkaline batteries.
Duracell Industrial batteries are there current professional battery range, taking over from duracell procell.
Under real life usage we have seen duracell aa batteries last up to 9 weeks on a usage cycle of 1.5 hours per week, and in conference situations give between 7 and 9 hours of continuous operation.
We recommend all our customers to use duracell industrial batteries in there audio devices.
