In the blood pressure monitors sector, battery reliability directly impacts product performance and user safety. APTPES addresses this with a 7.4V 4250mAh (0.2C discharge) lithium-ion battery pack featuring 2S1P (Two series, one parallel) cell arrangement, multi-layer protection circuitry, and factory-calibrated quality control. The pack supports extended runtime for demanding workloads while maintaining stable voltage across discharge cycles. OEM and wholesale inquiries welcome.
Integrated Multi-Protection Circuit: The built-in protection IC monitors 7.4V cell voltage in real time, guarding against overcharge, over-discharge, overcurrent, and short circuits. This prevents catastrophic cell failure during abnormal operating conditions.
Precision Cell Matching: Each lithium-ion cell undergoes capacity grading and internal resistance sorting before assembly into the 2S1P (Two series, one parallel) configuration. This matching process ensures uniform charge and discharge across all cells, extending pack lifespan and maintaining voltage stability.
Factory-Tested Quality Assurance: Every battery pack completes a full electrical testing cycle at our Dongguan facility, including charge retention verification, protection board trigger validation, and dimensional inspection. Test reports accompany each batch shipment for OEM traceability.
Global Certification Compliance: Manufactured to meet CE, RoHS, UN38.3, and MSDS documentation requirements. These certifications enable duty-free import into EU markets and compliant air freight for international distribution channels.
Plug-and-Play Terminal Integration: Factory-assembled with terminal wires and connectors, ready for direct integration into device PCBs without additional soldering or wire preparation.
Extended Cycle Life: The lithium-ion cells exhibit no memory effect and maintain over 80% capacity retention after 500 full charge-discharge cycles. Low self-discharge characteristics (under 3% per month) support long-term storage without significant capacity loss.
Wide Operating Temperature Range: Designed for Charging: 0°C ~ +45°C; Discharging: -20°C ~ +60°C, the pack maintains stable performance across diverse environmental conditions. Cold-weather and high-temperature variants are available through OEM customization.

Primary deployment scenarios include blood pressure monitors, where the 7.4V 4250mAh (0.2C discharge) capacity supports extended operation between charges. The pack also serves medical diagnostic devices requiring compact power integration with safety-certified construction. Distributors supplying health monitoring equipment can leverage this pack's CE and UN38.3 compliance for streamlined customs clearance and retail channel entry.
A: Yes. Wire length, gauge, and terminal connector model can be modified to match your device PCB interface. Common customizations include Molex, JST, and custom pin configurations. Provide your connector specification and required wire length for DFM review and quotation.
A: Lithium-ion battery packs must not be disposed of in standard waste streams. Follow local e-waste regulations and battery recycling programs. The pack contains recoverable lithium, copper, and aluminum materials. APTPES can provide end-of-life handling guidance for volume customers.
A: Standard warranty covers manufacturing defects for 12 months from shipment date. This includes cell capacity degradation below 80% of rated capacity under normal use conditions. Warranty does not cover damage from improper charging, physical impact, or operation outside specified temperature ranges.
A: Yes. All packs are UN38.3 certified and shipped with proper dangerous goods documentation (IATA/IMDG compliant). Packs are packaged in UN-rated boxes with insulation and short-circuit protection. Our logistics team handles DG declaration paperwork for international air and sea freight.
A: Use a dedicated lithium-ion charger with 8.4V (±0.05V) output in CC/CV (constant current/constant voltage) mode. Standard AC/DC adapters without CC/CV regulation will damage the protection IC and risk thermal runaway.
