The size and type of battery has an impact as well as the thickness of your skin where it covers your implant. Streaming from compatible Apple® 1 or Android™ 2 devices and using Cochlear True Wireless™ devices can also have an impact on your sound processor’s battery life.
The high-voltage battery modules are connected to the base of the battery housing by a thermally conductive paste. The aluminium heat sink is also connected to the housing base with a thermally conductive paste. The solid aluminum underbody guard protects the heat sink from mechanical damage.
Daily battery life varies for every sound processor user and is dependent on a variety of factors. Some of these factors include the programs and sound processor functions you use every day, your sound environment or volume levels. The size and type of battery has an impact as well as the thickness of your skin where it covers your implant.
As shown in Figure 1, there are two main locations where you can measure current: top of stack (high-side sensing) and bottom of stack (low-side sensing). Figure 1. Top of Stack vs. Bottom of Stack in a Battery Management System
A maximum of four battery modules are connected to each battery module control unit. Two or three control units are used, depending on the size of the battery. The 22-pin connections connect the battery modules control units to the individual battery modules.
You can use disposable or rechargeable batteries with the Nucleus 8 Sound Processor. It offers a typical battery life of 35 hours using zinc air disposable batteries.
