When is “Extreme Performance”not appropriate?
Since Rayovac Extreme Performance is designed specifically for heavy drain devices, when used in those applications that do not require additional power, conventional hearing aid wearers may experience shorter battery life.
For conventional hearing aids, we recommend Rayovac Advanced Extra batteries

Who needs Rayovac Extreme Performance?

• For people with next generation hearing instruments that incorporate the latest wireless functionality
• For people who wear very high gain or high power instruments
• For people whose devices give low battery warnings or cut out in loud environments
  

As these instruments pull a heavy power load, standard zinc air cells cannot always maintain the higher operating voltages required and wearers may therefore experience shortened battery life.
Extreme Performance overcomes these problems and meets the specific demands of this power hungry group of hearing devices by providing improved up-front voltage and greater stability during high drain discharge.

The new Rayovac Extreme Performance is available in  size 13 and 312.
(Size 10 is coming later in 2008)
