FAQ for Covert Audio Recorder Batteries
A: This is a function of the battery’s capacity and the recorder’s power consumption. We can design a high-capacity battery that, paired with an efficient audio SoC, can achieve recording times of 500, 1000, or even more hours.
A: We are constantly pushing the boundaries of miniaturization. We can produce cells with dimensions of just a few millimeters, but the final size is always a trade-off with capacity. Please contact us with your specific constraints.
A: Due to the high degree of custom engineering and the specialized nature of this market, our MOQ for a new design typically starts at 20,000 to 50,000 units.
A: This is our core expertise. We use the highest energy density materials available. This means for any given size, we can pack in more mAh (capacity), or for any given capacity, we can make the battery smaller.
A: Yes, it is absolutely critical for safety. We use ultra-small PCM boards that provide all necessary protections (over-charge, over-discharge, short-circuit) in a minimal footprint.
A: Given the precision required, the lead time for the first batch of functional prototypes is generally 6-8 weeks after design finalization.
A: We take confidentiality extremely seriously. All projects begin with a mutual Non-Disclosure Agreement (NDA), and access to project details is strictly limited to essential personnel within our organization.
A: Our ultra-low self-discharge chemistry is perfect for this. The battery can remain in a low-power standby state for many weeks or months, ready to start recording instantly.
A: They are typically charged via a discreet USB port on the host device. We design the battery and its PCM to be fully compatible with standard 5V USB charging.
A: After an NDA is in place, please provide a 3D model of the available space, the target recording and standby runtime, the power consumption profile of your electronics, and your estimated annual volume.
