FAQ for Office & Productivity Batteries
A: We use a combination of high-energy-density cells to maximize capacity and a specialized low self-discharge chemistry to minimize passive power drain when the device is idle.
A: We can manufacture ultra-thin cells with a thickness of less than 3mm, and often create custom, non-rectangular shapes to fit around other internal components.
A: For a new custom design, our MOQ typically starts at 20,000 to 50,000 units, depending on the complexity.
A: Yes. We can use higher-discharge-rate cells that can handle the high polling rates and power demands of gaming sensors and RGB lighting.
A: Our batteries are designed for a long product life, typically specified to retain high capacity after 300-500+ charge cycles.
A: After the design is finalized, the lead time for the first batch of prototypes is generally 4-6 weeks.
A: Yes, all our rechargeable battery solutions for office peripherals include an integrated PCM to protect against over-charge, over-discharge, and short-circuits.
A: Absolutely. We can engineer the battery to be compatible with USB-C and other standards, allowing users to get hours of use from just a few minutes of charging.
A: Yes, we manage the entire certification process to ensure your product’s battery meets all required standards for your target markets, including CE, UL, IEC, and UN38.3.
A: Please provide the target dimensions (or a 3D model of the space), required minimum runtime (days/weeks/months) or capacity (mAh), voltage (3.7V), and your estimated annual volume.
