Introduction
Modern electronic devices, while sophisticated, often have an Achilles' heel: their proprietary batteries. The Sennheiser BA2015 battery pack is a perfect example of this issue. Designed specifically for certain wireless microphones from the brand, this battery is not only expensive but also difficult to replace with standard solutions. However, with a bit of know-how and some affordable components, it's possible to clone this battery and save substantial amounts.
Why Bother Cloning?
At $80-100 each, investing in multiple Sennheiser BA2015 batteries can quickly add up, especially if you own several microphones to power. Yet, the technology behind these batteries is far from groundbreaking. They simply contain two NiMH AA batteries and an NTC temperature sensor, a component that costs as little as $0.02 for the simplest versions.
Necessary Components
To clone a Sennheiser BA2015 battery, you will need:
- Two high-quality NiMH AA batteries (around $2.50 each for equivalent specs)
- An NTC temperature sensor ($0.02)
- A suitable casing to house these components
- Basic soldering and electronics skills
Cloning Steps
1. Preparing the Batteries
Choose high-quality NiMH AA batteries, such as those manufactured by Panasonic. They should offer similar capacity and voltage to the original cells to ensure optimal performance.
2. Installing the NTC Sensor
The NTC sensor is essential to prevent the charging of non-rechargeable batteries. Solder the sensor between the two battery terminals to simulate the functionality of the original pack.
3. Assembling the Case
Use a compatible casing, preferably an adapted third-party model, to secure the components. Ensure the casing allows for easy connection with the microphone.
Benefits and Precautions
Cloning your own battery can save you up to 90% of the cost of original batteries. However, it's crucial to understand the process well and verify that the components used are compatible and secure. A poor assembly could damage the microphone or cause malfunctions.
Conclusion
Cloning a Sennheiser BA2015 battery is an economical and relatively simple solution for DIY enthusiasts. This method not only reduces costs but also allows you to customize the performance of your devices.
