LTO0412 Super capacitive lithium battery 9

Huahui Energy's 4mm-diameter, 12mm-height, 3.5mAh cylindrical small titanate lithium battery offers significant advantages in steak barbecue thermometers and active styluses. Its core strengths lie in ultimate safety, high-rate fast charging, ultra-wide temperature adaptability, and long lifespan, perfectly meeting the stringent scene requirements of both devices.

✍ Active Stylus: The "Experience Multiplier" for Writing & Battery Life

Ultra-compact Size, Lighter Pen Body

With dimensions of only 4mm in diameter and 12mm in height (model number: HTC0412) and a weight of approximately 0.35g, it can be directly embedded inside the pen body without compromising the integrated design and hand feel, solving the "top-heavy" issue common with ordinary batteries.

High-rate Fast Charging, Say Goodbye to Long Waiting

Supporting 1~40C discharge rates, it delivers stable instantaneous power to drive in-pen pressure sensing, Bluetooth communication, and other modules. Meanwhile, its fast charging capability enables rapid energy replenishment, satisfying the high-frequency demand of "charge and go" for creators.

Wide Temperature Durability, Stable Performance Across All Scenarios

Operating over a wide temperature range of -40°C to 100°C, it maintains excellent capacity retention in extreme cold or heat. It prevents disconnections or signal loss caused by temperature variations, making it suitable for outdoor, automotive, and various other scenarios.

Long Lifespan, Reduced Maintenance Costs

With a cycle life of over 10,000 charges—10 times that of ordinary lithium batteries—it significantly extends the stylus's service life, reduces replacement frequency, and is ideal for professional drawing and frequent writing users.

Ultimate Safety, Preventing Device Damage

Titanate lithium materials do not generate lithium dendrites. It passes extreme tests such as needling and crushing without catching fire or exploding, avoiding overheating or short-circuit damage to the pen body and ensuring user safety.

🍖 Steak Barbecue Thermometer: The "Reliable Heart" for Extreme Environments & Long-term Monitoring

Wide Temperature Resistance, Built for the Entire Cooking Process

It operates stably across -40°C to 100°C, reliably enduring both refrigerator pre-cooling and barbecue oven high temperatures. It ensures continuous and accurate temperature data transmission without signal interruption.

High Safety, Eliminating Hidden Dangers

As a power source for devices inserted into food, its non-flammable and non-explosive properties prevent safety hazards at the source. Additionally, its stable material composition prevents harmful substance precipitation, guaranteeing food safety.

Long Lifespan, Suited for Long-term High-frequency Use

With a cycle life of over 4,000 charges, it supports repeated long-term use of barbecue thermometers, reducing operational and maintenance costs for commercial equipment and fitting high-frequency scenarios in restaurants and households.

Low Internal Resistance, More Stable Signal Transmission

With an internal resistance of ≤1400mΩ and a stable output voltage (nominally 2.4V), it ensures clear signal transmission for Bluetooth and temperature sensor modules, avoiding data errors from voltage fluctuations and precisely controlling doneness.
