Rated at 3.7V nominal voltage and 920mAh (0.2C discharge) capacity, this APTPES lithium battery pack targets electric shavers where space and weight constraints are critical. The lithium-ion cell architecture configured as 1 series 1 parallel (1S1P) provides balanced energy density. A built-in protection IC safeguards against overcharge, over-discharge, and short circuits. Factory-assembled with terminal wires for plug-and-play integration. Contact our engineering team for customization inquiries.
Integrated Multi-Protection Circuit: The built-in protection IC monitors 3.7V 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 1 series 1 parallel (1S1P) 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.
Low Self-Discharge Design: Advanced lithium-ion chemistry limits self-discharge to under 3% per month at room temperature. -20℃ ~ +45℃ (recommended to store in a half-charge. This characteristic supports inventory rotation and device storage without frequent recharge maintenance.
Balanced Thermal Management: Cell spacing and wrapping materials facilitate passive heat dissipation during charge and discharge cycles. The pack design prevents thermal hotspots that accelerate cell degradation, contributing to consistent long-term performance.
Compact Energy Density: The lithium-ion cell platform delivers high energy density relative to pack volume, making it suitable for portable and embedded applications.

A: The stated dimensions refer to the battery cell body. Wire terminals extend an additional 20-80mm beyond the cell dimensions. Reserve space for wire routing in your device housing design.
A: The maximum continuous discharge current is 1.0C (approx. 920mA, limited by protection board). Verify your device's steady-state current draw and startup surge requirements against these ratings. If your application needs higher current, we can customize the cell selection and protection board parameters.
A: Each battery pack ships with CE, RoHS, UN38.3, and MSDS documentation. UN38.3 test summaries cover altitude, thermal, vibration, and impact testing required for air freight compliance. Material safety data sheets are available in English for customs and regulatory submission.
A: Store packs at -20℃ ~ +45℃ (recommended to store in a half-charged state). Maintain charge level between 30-50% for long-term storage. Perform a maintenance charge every 6 months to prevent deep discharge degradation. Avoid storing in direct sunlight or high-humidity environments.
A: MOQ is flexible based on cell availability and customization requirements. Standard configurations ship within 7-15 business days. Custom OEM orders with modified wire lengths, connectors, or protection parameters require 15-25 business days including prototype sampling. Contact our sales team for a detailed quotation.
