From Makers Electronics's description

TENPOWER INR18650-28HE Rechargeable 18650 Li-ion Battery High Drain 3.6V 10A 2800mAh (NEW) The TENPOWER INR18650-28HE is a cylindrical lithium-ion cell that embodies the balance between energy and performance. Its name hints at capacity (28 = 2800 mAh) and a design for relatively high current. Encased in the familiar 18650 shell, it looks compact and familiar, blending into battery packs or individual use seamlessly. The outer wrapper is printed with model codes and safety markings. Inside the steel cylinder lies layered lithium chemistry built for both energy density and stable output. The cell is engineered to respond reliably under load, delivering its stored chemical energy into electrical current with minimal internal resistance losses. Though its design is simple in outward form, the internal architecture is carefully arranged: electrodes, separators, electrolyte, and safety vent structures all cooperate to maintain performance and safety. The cell feels solid in hand, with firm construction, and its terminals present the expected positive and flat-negative ends. When integrated into devices or battery packs, the INR18650-28HE becomes a dependable power source. Its moderate discharge capabilities make it suitable for applications where bursts of current are needed but long-lasting energy is also valued. It can be placed in series or parallel arrays, be partially charged or discharged over its life, and integrated with battery management systems. Though it’s unprotected (i.e. no built-in circuit), when used properly it offers a predictable and stable power backbone for a wide range of electronics whether portable tools, flashlights, or backup systems. Features: High energy density design. Moderate high-drain capability. Low internal resistance. Reliable chemical stability. Long cycle durability. Safety vent / pressure relief mechanism. Flat negative terminal (common 18650 form). Specifications: Parameter Value / Detail Nominal capacity: 2800 mAh (minimum 2760 mAh) Nominal voltage: 3.6 V Charge cutoff voltage: 4.20 V ± 0.05 V Discharge cutoff voltage: ≈ 2.50 V Maximum continuous discharge: 10 A (at 25 °C) Internal resistance (AC, 1 kHz): ≤ 30 mΩ (at 25 °C) Dimensions (max): Diameter ≤ 18.55 mm, height ≤ 65.10 mm (typical 18650) Cell weight: ~46.0 g (maximum) Operating discharge temperature: –20 °C to +60 °C (surface) Charging temperature range: 0 °C to +45 °C (depending on charge current) Storage temperature (various): –20 °C to +60 °C depending on storage duration (1 mo, 3 mo, 1 year) Applications: Portable electronics.

From Micro Ohm's description

Tenpower INR18650-28HE Rechargeable Li-ion 18650 Cell – 2800 mAh, 3.6 V (Max 10 A) Overview The INR18650-28HE from Tenpower is a cylindrical 18650 lithium-ion cell balancing solid energy (nominal 2800 mAh , min 2760 mAh ) with dependable current handling up to 10 A continuous at room temperature. Standard CC-CV charging to 4.20 ± 0.05 V with 0.5C (1400 mA) and 56 mA termination ensures long service life. It ships around 30% SOC for safety and storage stability. Dimensions are classic 18650 ( ≤65.10 mm × ≤18.55 mm ) for drop-in pack builds. Key Advantages ✅ Real 2800 mAh class: Nominal 2800 mAh (min 2760 mAh ) at 0.2C to 2.5 V . ⚡ Up to 10 A discharge: Rated 10 A continuous at 25 ± 3 °C ; robust rate table confirms strong capacity retention at high currents. 🔌 Flexible charging: CC-CV with 4.20 V limit and 56 mA cut-off; recommended charge currents by temperature (0–45 °C). 🧊 Wide operating window: Discharge −20 to 60 °C ; charge windows scaled for low-/mid-/high-temp operation. 🧪 Cycle durability: After 500 cycles (0.5C charge / 1C discharge window) capacity remains ≥80% of first discharge. 🧲 Low impedance: Initial ≤30 mΩ @ 1 kHz for crisp voltage under load. 📏 Standard 18650 size: ≤65.10 mm length , ≤18.55 mm diameter (with wrap). Typical Applications 🔦 High-output flashlights & searchlights 🧰 Power-tool battery rebuilds (with proper BMS) 🔋 DIY e-bike / scooter sub-packs and USB power banks 🧪 Lab instrumentation & portable test gear ⛑️ Backup/UPS buffer packs & IoT gateways Specifications Parameter Value Model INR18650-28HE Nominal Capacity 2800 mAh (min 2760 mAh ) @ 0.2C to 2.5 V Nominal Voltage 3.6 V Charging Method CC-CV to 4.20 ± 0.05 V , terminate at 56 mA Standard / Rapid Charge Current 1400 mA (0.5C) / 2800 mA (1C) Max Continuous Discharge 10 A @ 25 ± 3 °C Internal Impedance ≤30 mΩ (1 kHz, 25 ± 3 °C) Operating Temp (Charge) 0–10 °C: 560 mA; 10–20 °C: 1400 mA; 20–45 °C: 2800 mA Operating Temp (Discharge) −20 to 60 °C Storage Temperature 1 yr −20~25 °C; 3 mo −20~45 °C; 1 mo −20~60 °C (≥90% recovery if stored ~30% SOC) Dimensions ≤18.55 mm dia × ≤65.10 mm length (with sleeve) Shipping State ~30% SOC , OCV 3.47–3.62 V Performance Highlights 📈 Rate capability (relative to standard 25 °C capacity): 0.56 A: 100% , 1.4 A: 96% , 2.8 A: 93% , 5 A: 93% , 10 A: 97% . 🌡️ Temperature behavior at 1C: −10 °C: 60% , 0 °C: 70% , 25 °C: 93% , 60 °C: 93% . 🔁 Cycle life : ≥ 80% of first-cycle capacity after 500 cycles (0.5C CC-CV charge, 1C discharge to 2.5 V). Integration & Pack Design (Pro Tips) 🛡️ BMS Required: Implement OVP <4.25 V , UVP ≥2.5 V , over-current and short-circuit protection; use low-leakage designs to avoid storage drain. 🔩 Spot-weld only: Do not solder directly to the cell; weld nickel tabs and then solder wires to the tabs/PCB. 🧯 Thermal/charge rules: Charge strictly CC-CV ; pre-charge below 3.0 V at ≤0.2C ; never exceed 4.25 V . 📦 Storage: Keep dry, avoid pressure/shock; for long storage keep at low temp and around 30% SOC ; reactivate every ~3 months per datasheet procedure. Safety Summary (User-Facing) 🚫 No fire/water/shorts; do not reverse-polarity or over-charge/over-discharge; avoid direct sun and mechanical shock. 🧪 Electrolyte contact: rinse with water and seek medical help; keep away from children. 📉 When power sags, stop use to prevent deep discharge; recharge in a ventilated area once cooled.
