606090 3.7V 4000mAh LiPo Battery: The 6mm Ultra-Thin 14.8Wh Cell for Tablets, Monitors & Smart Displays

When a device spans a wide 60 × 90mm area but must stay under 7mm thick, the 606090 3.7V 4000mAh LiPo battery is the natural choice. This lithium polymer cell spreads 14.8Wh of energy across a large, flat 6.0 × 60 × 90mm footprint — the ideal power source for ultra-thin tablets, portable all-in-one monitors, slim laptop battery packs, and large smart-home display panels where preserving a sleek profile matters more than anything else.

This guide covers the HNF-606090 cell’s specification, its ultra-thin mechanical design, and the display-class applications where a wide, flat LiPo beats every cylindrical or prismatic alternative.

Why the 606090 Format: 4000mAh in 6mm

The model number encodes the cell’s geometry. The 606090 LiPo measures:

• 60 = 60mm width
• 60→90 = 90mm length
• 90 = 90mm length
• 4000 = 4000mAh capacity

The result is a 1S1P (single cell, single parallel) lithium polymer battery with a footprint of 6.0 × 60 × 90 mm and a weight of approximately 75g. Spreading 4000mAh over a 60×90mm plane keeps the cell under 7mm thick — the most energy-dense way to deliver this capacity at 3.7V in a flat package.

Key Advantages of the 606090 LiPo Cell

• Ultra-thin 6mm profile — sits behind screens and panels where thickness is the limiting dimension.
• High energy density at 3.7V — 14.8Wh in a flat, large-area footprint.
• 100mΩ ultra-low impedance — efficient, stable high-current discharge for demanding loads.
• Lightweight at 75g — 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 606090 3.7V LiPo Is Used

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

1. Ultra-Thin Tablet Computers

Tablets compete on thinness. A 6mm LiPo behind the display assembly delivers all-day runtime without thickening the chassis — exactly what the 606090 was built for.

2. Portable All-in-One Monitors

USB-C portable monitors need a battery that fills the panel area rather than bulging out the back. The 60×90mm cell spreads evenly and keeps the monitor slim.

3. Slim Laptop Battery Packs

Ultrabook and 2-in-1 designs use large flat cells in the keyboard deck. The 606090’s low 100mΩ impedance supports the burst current of compute-heavy sessions.

4. Large Smart-Home Display Panels

Countertop and wall displays need hidden, flat power. The cell tucks behind the panel with no visible battery bulge and runs for months on standby.

5. Battery-Powered Portable Projectors

Pocket and mini projectors draw steady current from a large flat cell. 4000mAh supports a full presentation or movie on a single charge.

Safety, Certification & Shipping

At 14.8Wh the HNF-606090 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 606090 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.
