112270 3.7V 2000mAh LiPo Battery: The Slim 11×22×70mm Cell for Remote Controls, Stylus Pens & Slim Devices

When a device is only 11mm wide but needs real run-time, a standard cylindrical cell simply will not fit. The 112270 3.7V 2000mAh LiPo battery was engineered for exactly this constraint: a slim, elongated lithium polymer pouch cell that is 11mm wide, 22mm deep, and 70mm long. At 3.7V nominal and 2000mAh (7.4Wh), it delivers the energy density of a much larger pack inside a profile thin enough for remote controls, stylus pens, wireless keyboards, and handheld barcode scanners.

This guide breaks down the HNF-112270 cell’s specifications, mechanical design, and the real-world applications where a narrow strip LiPo outperforms every alternative. If you are specifying power for a space-constrained consumer or industrial device, read on.

Why the 112270 Format Exists: Slim-Profile Power

Most lithium cells come in fixed shapes — 18650 cylinders, prismatic blocks, or coin cells. None of those fit a device that is 11mm wide but 70mm long. The 112270 LiPo solves this with a pouch (lipo) construction that can be cut to almost any rectangular footprint. The numbers in the model name describe the cell exactly:

• 11 = 11mm width (the thin dimension)
• 22 = 22mm depth
• 70 = 70mm length
• 2000 = 2000mAh capacity

The result is a 1S1P (single cell, single parallel) lithium polymer battery with a footprint of just 11 × 22 × 70 mm and a weight of approximately 38g. That is the kind of space efficiency that lets a product designer reclaim internal volume for electronics, antennas, or a thinner housing.

Key Advantages of the 112270 LiPo Cell

Beyond its unusual shape, the HNF-112270 brings the core benefits that make lithium polymer the default choice for portable electronics:

• High energy density with stable 3.7V output — a predictable voltage curve across the discharge cycle.
• High-drain capable — supports up to 1.0C continuous discharge (2000mA) for bursty loads like RF transmission.
• Ultra-thin and lightweight — at 38g and 11mm wide, it disappears into slim housings.
• Safe and long-lived — PCM protection against over-charge and over-discharge, ≥500 cycles at 80% retention.
• Wide temperature range — discharges reliably from -20°C to +60°C.
• Customizable dimensions — HNF manufactures pouch cells to customer-specified widths, lengths, and capacities.

Where the 112270 3.7V LiPo Is Used

The narrow-strip form factor maps directly onto a set of devices where width is the binding constraint. The most common applications include:

1. Remote Controls & Smart Remotes

TV, set-top, and IoT remotes are getting thinner while adding voice, RF, and backlight features. A 2000mAh LiPo gives months of standby in a profile that fits inside a 12mm housing, replacing bulky AAA holders.

2. Stylus Pens & Active Pen Electronics

Active styluses need a long, thin power source that will not shift the center of gravity. The 112270’s 70mm length and 11mm width are a natural fit, and its low self-discharge keeps the pen ready between uses.

3. Wireless Keyboards & Mouse Peripherals

Slim keyboards and compact mice benefit from a flat cell that spreads along the chassis instead of bulging. 7.4Wh is enough for weeks of wireless use per charge.

4. Handheld Barcode Scanners

Retail and warehouse scanners run scan motors, displays, and Wi-Fi radios on tight duty cycles. A 1.0C-capable LiPo supports the burst current while the pouch shape tucks into an ergonomic grip.

5. Slim Bluetooth Earphone Charging Cases

Charging cases live or die by internal volume. The 112270 delivers 2000mAh for multiple earbud recharges in a strip that wraps around the case interior.

Safety, Certification & Shipping

At 7.4Wh the HNF-112270 sits far below the 100Wh air-freight threshold, so it ships by air with standard MSDS and UN38.3 documentation — no special cargo 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 112270 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.
