VTC-LP715868LT 3.7V 3500mAh Low Temperature Li-ion Polymer Battery
This article summarizes the technical information extracted from the VTC-LP715868LT DOCX specification dated 2025-9-12 and the product images in the source folder. No PDF file was present, so the article uses DOCX text and embedded DOCX media instead of PDF screenshots.
Product Overview
The VTC-LP715868LT is specified as a Li-ion polymer rechargeable battery manufactured and supplied by VTC Power Co., Ltd. The model is listed as VTC-LP715868LT, with 3.7V nominal voltage and 3500mAh nominal capacity. The product photos show a silver pouch cell, yellow edge tape, red and black wire leads, and a small white 2-pin connector.
Core Electrical Parameters
The datasheet lists 3600mAh rated capacity at 0.2C discharge and 3500mAh nominal capacity at 0.2C discharge. The minimum capacity line appears as 34000mAh in the source; because this conflicts with the model and the surrounding capacity values, this package treats it as a likely 3400mAh typo and records the assumption in the summary. Limited charge voltage is 4.2V and discharge cut-off voltage is 3.0V.

Pack Size and Structure
The cell drawing table gives 7.1mm initial maximum thickness, 7.6mm maximum thickness after 600 cycle life, 58.0mm maximum width, and 68.0mm maximum height. Tab details include 4~8mm tab length, 45±1.5mm tab pitch, 5±0.2mm tab width, and 4±1mm top sealant length. The product photos add practical pack-integration context by showing wire leads and a small connector.
Operating Temperature and Storage
Operating temperature is specified as 0~45°C for charging and -40~60°C for discharging, with operating humidity at ≤90%RH. The storage section lists -20~+45°C for short periods under one month, -10~+45°C for long periods over three months, and 15~35°C recommended storage with 85%RH maximum.
Cycle Life, Retention, and Safety Tests
The electrochemical section states cycle life is not less than 600 cycles under the listed 0.2C CC-CV charge and 0.2C discharge test method until capacity is reduced to 80% of rated capacity. Self-discharge capacity is listed as not less than 85% of initial capacity after 28 days at 20±5°C followed by 0.2C discharge. Safety and environmental tests are summarized in the source, including humidity, vibration, shock, overcharge, short-circuit, and thermal tests, but no third-party certification claim is made here.
Application Fit
The low-temperature discharge range, flat pouch structure, and 3500mAh capacity make this battery relevant for cold chain temperature data loggers, GPS asset trackers, outdoor environmental sensors, smart locks, handheld terminals, irrigation controllers, and portable diagnostic instruments. Final use should be matched to the actual load profile, charge environment, enclosure design, and connector requirements.
OEM/ODM Supply Notes
For device makers and battery distributors, VTCBATT can support sample development and factory-direct supply based on enclosure size, connector type, wire length, labeling, protection circuit, and application test requirements. Technical confirmation should be completed before mass production, especially where low-temperature discharge, rapid charge, maximum discharge current, or long storage conditions are part of the device specification.
