3.7V 501015 50mAh Mini Lithium Polymer Battery

VCELL Power is a leading manufacturer of 3.7V 501015 50mAh Mini Lithium Polymer Battery which is specifically engineered for devices where every millimeter and every gram matters.

Engineered for Extreme Space Constraints

Dimensions That Unlock Slimmer Product Designs

The Mini Lithium Polymer Battery measures just 5.2mm × 10.5mm × 17.5mm. For hardware engineers, this means:

5.2mm thickness -- Fits into earbud stems, watch housings, and pen barrels where thicker cells cannot go

17.5mm length -- Matches the footprint of miniaturized PCBs

~2.0g weight -- Adds negligible mass to wrist-worn or in-ear devices

50mAh in a Sub-2cm Envelope -- Energy Density Optimized

Despite its miniature size, the 3. Mini Lithium Polymer Battery delivers a full 50mAh nominal capacity. This energy density allows wearable devices to operate for full daily use cycles between charges.

0.2C standard discharge current (10mA) for steady operation

1.5C max continuous discharge (75mA) supports peak loads

5.0C peak (250mA for <3 seconds) handles pairing bursts or display refreshes

Safety Certified for Body-Worn Devices

Why Safety Matters More in Miniature Batteries

When a 3.7V 501015 50mAh Mini Lithium Polymer Battery powers a device worn in the ear, on the wrist, or held in hand, failure is not an option. VCELL Power builds this cell with:

1. High-quality separators -- Prevent internal shorts even under mechanical stress

2. Advanced sealing processes -- Eliminate electrolyte leakage risk

3. Strict voltage control -- 4.2V charge cut-off, 2.75V discharge cut-off

Certifications That Simplify Global Market Access

This Battery carries certifications required for wearable electronics worldwide:

Built-in Protection Without External Components

The Battery operates within safe electrical limits by design:

1. Max charge current: 1.0C (50mA)

2. Max continuous discharge: 1.5C (75mA)

3. Peak discharge: 5.0C (250mA) for <3 seconds

4. Charge temperature range: 0~45℃

5. Discharge temperature range: -20~60℃

Engineers can integrate this cell without adding external protection circuitry for basic safety, saving PCB space.

700+ Cycle Life -- Built to Last Through Daily Wear

Longevity That Matches Device Lifecycles

The Battery delivers >700 cycles at standard charge/discharge conditions. For a wearable device charged daily, this means:

Over 2 years of daily charging before reaching 700 cycles

5 years of service life with partial cycling

Fewer warranty claims related to battery degradation

No Memory Effect -- User-Friendly Recharging

Unlike NiMH alternatives, this 3.7V 501015 50mAh Mini Lithium Polymer Battery exhibits zero memory effect. End users can:

1. Recharge at any state of charge without capacity loss

2. Top up batteries partially without "confusing" the cell

3. Avoid scheduled full discharges that inconvenience users
