Renata “maratone” – The New leader in battery performance! After more than 12 years of research and development, Renata, the Swiss battery producer, claims they have managed to set the new benchmark for top quality hearing aid battery performance. According to Henry Kessler of Sy Kessler Sales, Official North American Importer for RENATA, this new generation battery has more than enough power to supply even the most demanding digital hearing aids – “for a record setting endurance marathon run time.” The performance is so good; Renata decided to launch it under a new name, “maratone.” 
Energy for the long run – exceeding expectations! How to compare different batteries from different manufacturers? Organisations such as ANSI and IEC are developing standardized tests with the aim of providing the hearing industry with a common platform for comparing the battery performance of multiple manufacturers. One standard test valid for zinc-air batteries is based on a discharge of the battery under a constant resistance over a period of time, which varies depending upon the battery type being tested. When comparing RENATA maratone to the leading competitive products under this standard test, “maratone” clearly features a superior performance advantage. ZA 13 maratone: Standard Discharge
 - standard discharge
- according to IEC-60086-2
- 1500 Ohm
- 12h testing at 20°C to 0.9V at 50% rh

 | Realizing that today’s modern hearing instruments have much more demanding power requirements, IEC proposed a new “high power pulse test” for battery performance analysis which more closely simulates reality than the standard battery discharge tests described above. This test implements a constant load over a specified period of time, with the addition of a more substantial pulse load every two hours. Likewise, this test also varies depending upon the battery type being analyzed. One critical aspect of these tests is that the battery voltage must remain above the area of 1.1V or the low battery warning feature in many of these modern instruments will trigger or the aid will simply shut down. Once again, Renata maratone clearly features a superior performance advantage over the leading competitors even under this more stringent “high power pulse test,” indicating RENATA maratone is truly “the battery of choice.” ZA 312 maratone: High-Power-Puls-Discharge
 - high-power-pulse discharge
- according to IEC-60086-2 35/1185/CD
- 12h testing at 20°C to 1.1V at 50% rh
- 100ms every 2h, 2/10mA

| Why is the battery choice critical for modern digital hearing instruments? Modern hearing instrument manufacturers are constantly striving to provide consumers with intelligent hearing solutions – all designed to perform optimally under an ever changing multitude of environmental surroundings. This push for enhanced performance has helped to create a growing variety of truly innovative features. These enhancements have lead to high current pulses which the battery must be capable of sustaining. If the battery can’t handle the load, which can become especially high in some environments, these innovative hearing devices will simply fail to function as designed, leaving consumers uncomfortable with their investment in better hearing. This means selecting the best battery is indeed a crucial decision.
In order to exceed expectations, Renata went a step further and created testing conditions believed to simulate heavy use in a rough environment. Under this special Renata test, high power pulses are applied every second draining the batteries much more rapidly. This harsh yet realistic test closely simulates the difficulties such high tech hearing devices face. Once again, when top quality battery performance is demanded under even the harshest conditions, the test results point toward Renata as the obvious solution.

Can Renata’s test results be duplicated by an independent laboratory? Yes. As a matter of fact, an independent lab in Denmark, called “Delta” made an "in-situ-test,” which means they tested our batteries in two different digital hearing aids - together with fresh batteries from Rayovac, PowerOne and others. Multiple batteries were tested under normal levels of temperature and humidity, in a variety of sound environments and indeed, the results indicated Renata’s superior “blue ribbon - first place” performance!
Renata suggests that you do your own test, and let your patients decide for themselves! Although it is a “marathon race,” and not a sprint, one thing is crystal clear, Renata has the lead today! ZA 10 maratone: "In-situ"-Test
 - hearing aid type 1
- 16h testing at 18–27°C
to 1.1V at 30–60% rh - various sound environments
