Professional tool users demand the most from their batteries: high power, stable performance, long runtime, and fast charging. At the 2026 China International Hardware Fair (CIHF), BAK Battery, under the theme “Empowering Every Professional Tool,” unveiled its latest all-tab technology solutions designed to address real user pain points and help tool manufacturers build more competitive products.
Addressing Core Pain Points: All-Tab 2170-50D2, Built for Professionals
In real-world professional tool applications, users often face challenges such as insufficient runtime, power drop under high loads, performance degradation in high temperatures, and failure to start in low temperatures. BAK Battery’s newly launched all-tab 2170-50D2 cell systematically addresses these pain points through targeted optimization.
-
Range Anxiety: With an energy density of 265Wh/kg, the cell significantly extends runtime per charge, reducing efficiency losses caused by frequent battery changes.
-
Power Drop: Ultra-low internal resistance of 5mΩ combined with 50A continuous discharge capability ensures stable output even under high-load conditions such as rotary hammers and chain saws, delivering power on demand.
-
High-Temperature Performance: The innovative solid-state electrolyte coating technology enhances stability under high-temperature conditions, ensuring excellent temperature control even during prolonged continuous operation.
-
Low-Temperature Performance: With a wide operating temperature range of -20℃ to 80℃, the cell enables reliable startup in freezing winter conditions or scorching summer job sites, ensuring all-weather usability.
“Professional tool applications are far more complex than consumer electronics. Users expect a holistic battery solution — high energy, high power, safety, and durability,” said a Product Manager at BAK Battery. “The all-tab 2170-50D2 is the result of our deep understanding of user pain points and systematic optimization at the electrochemical level.”
Scenario-Based Solutions: More Than Cells, Understanding Tool Applications
BAK Battery’s differentiation lies not only in its cells but also in its deep understanding of tool application scenarios. At the exhibition, BAK showcased tailored battery solution recommendations for different tool types, including:
-
High-Load Tools (Rotary Hammers, Chain Saws): Recommended all-tab 2170-50D2 for its low internal resistance and high rate capability to meet instantaneous high-current demands.
-
Long-Runtime Tools (Garden Tools, Vacuum Cleaners): Recommended high-energy-density series to maximize runtime per charge while maintaining power output.
-
Compact Tools (Screwdrivers, Drills): Recommended 18650-series all-tab products for the optimal balance of performance and size within limited space.
Additionally, BAK Battery provides end-to-end technical support spanning cell selection, battery pack design, and system integration, helping tool manufacturers shorten development cycles and enhance product competitiveness.
Quality Commitment: Starting with Every Single Cell
In the professional tool industry, reliability translates to productivity. BAK Battery’s fully automated smart factories enable end-to-end quality control from raw materials to finished products. Every 2170-50D2 cell shipped undergoes rigorous safety testing and consistency screening to ensure stable and reliable performance under demanding conditions.
“Empowering every professional tool is not just a slogan; it is our commitment to customers,” the Product Manager added. “Going forward, we will continue to engage with frontline tool users, listen to real-world needs, and partner with our customers to drive the electrification upgrade of the tool industry with advanced products and dedicated service.”
