606072 3.7V 3900mAh LiPo Battery: The 6mm Ultra-Thin 14.43Wh Cell for Tablets, Portable Monitors & Display Devices

When a device needs both a large footprint and serious runtime but cannot get any thicker, the 606072 3.7V 3900mAh LiPo battery is the answer. At just 6mm thin across a wide 60 × 72mm area, this lithium polymer cell packs 14.43Wh of energy into a package that disappears behind a tablet screen, a portable monitor, or a large-format e-reader. For product designers fighting the thickness battle, the 606072 delivers maximum capacity where width and length are available but depth is not.

This guide covers the HNF-606072 cell’s specification, its ultra-thin mechanical design, and the display-class applications where a wide, flat LiPo outperforms every cylindrical or prismatic alternative.

Why the 606072 Format: Maximum Capacity in 6mm

The model number tells the whole story. The 606072 LiPo measures:

• 60 = 60mm width
• 60→72 = 72mm length (the second 60 group is the width, 72 the length)
• 72 = 72mm length
• 3900 = 3900mAh capacity

The result is a 1S1P (single cell, single parallel) lithium polymer battery with a footprint of 6.0 × 60 × 72 mm and a weight of approximately 68g. Spreading 3900mAh over a 60×72mm plane keeps the cell under 7mm thick — the thinnest possible way to deliver this much energy at 3.7V.

Key Advantages of the 606072 LiPo Cell

• Ultra-thin 6mm profile — fits behind screens and displays where thickness is the limiting dimension.
• High energy density at 3.7V — 14.43Wh in a flat, large-area footprint.
• High-drain capable — 120mΩ impedance supports efficient, stable high-current discharge for demanding loads.
• Lightweight at 68g — minimal added mass for portable display devices.
• Safe and long-lived — PCM protection plus ≥500 cycles at 80% retention.
• Wide temperature range — discharges reliably from -20°C to +60°C.
• Customizable — HNF manufactures pouch cells to customer-specified dimensions and capacities.

Where the 606072 3.7V LiPo Is Used

The wide, flat form factor maps directly onto devices built around a screen or panel. The most common applications:

1. Tablet Computers & iPad-Style Devices

Tablets live or die by thinness. A 6mm LiPo sits behind the display assembly and delivers all-day runtime without thickening the chassis — the exact job the 606072 was designed for.

2. Portable Monitors & Secondary Displays

USB-C portable monitors need a battery that fills the panel area rather than bulging out the back. The 60×72mm cell spreads evenly and keeps the monitor under 10mm total.

3. Large-Format E-Readers

Big-screen e-readers and note-taking tablets draw steady current from a large flat cell. 3900mAh supports weeks of casual reading between charges.

4. Battery-Powered Digital Signage

Slim signage panels and menu boards run from a hidden LiPo layer. The 606072’s flat shape tucks behind the panel with no visible battery bulge.

5. Portable Medical Imaging Viewers

Mobile ultrasound and imaging viewers need reliable, flat power that meets medical certification. The cell’s CE/RoHS/IEC62133 compliance and stable discharge make it suitable for clinical portables.

Safety, Certification & Shipping

At 14.43Wh the HNF-606072 is far below the 100Wh air-freight limit, so it ships by air with standard MSDS and UN38.3 documentation — no dangerous-goods handling required. Every cell is built to CE, RoHS, and IEC62133 standards and protected by an onboard PCM against over-charge, over-discharge, and short circuit. HNF applies multi-stage quality control across R&D, incoming inspection, production, pre-shipment, and after-sales.

Customization & OEM Options

The 606072 is a standard catalog cell, but HNF Battery is a custom lithium battery manufacturer. Share your required voltage, capacity, and dimensions and the engineering team will propose a pouch cell, protection circuit, and connector configuration to match. In-stock items ship with no MOQ; custom cells typically start at 3,000–10,000 pcs depending on size and capacity. Samples are available and the sample cost is refunded once a bulk order is confirmed.
