If you’re looking for a solid, no-nonsense ICR 18650 battery 2200mAh 3.7V, this is the classic workhorse that a lot of brands still stick with. We make these in-house, so whether you need a simple bulk order or a custom setup for your device, we can pretty much shape the pack the way you want.
This cell sits at 3.7V nominal, hits 4.2V when fully charged, and holds a steady 2200mAh capacity. The energy comes in around 8.14Wh, which is more than enough for most small electronics, tools, lighting gear, or any project needing a stable single-cell setup.
Each cell is built in the standard 18×65mm size, and they’re rated for 500+ cycles, so you’re not swapping them out every few months. If you need custom wires, protection boards, connectors, or a full battery pack built around this cell, just tell us — we do OEM/ODM all the time.
Ideal for brands, wholesalers, and factories that just want reliable 18650 cells without overthinking it.
This 18650 3.7V 2200mAh lithium battery is a standard rechargeable cell widely used in industrial and consumer applications.
It is commonly selected for battery pack assembly and OEM production where stable output and consistent batch quality are required.
Typical use includes both standalone cells and multi-cell battery pack configurations.
Typical Applications
This battery is not limited to one industry. It is widely used in different end products, especially where compact size and stable discharge are required.
Consumer & Portable Devices
- Flashlights / torches
- Portable fans
- Handheld devices
- Toys and small electronics
Solar Lighting Systems
- Solar garden lights
- Solar wall lights
- Small solar street lights
- Outdoor LED lighting systems
Industrial & OEM Products
- Battery pack assembly (3S / 4S / 2P / 3P configurations)
- Security equipment
- GPS tracking devices
- Wireless monitoring devices
Why It Is Common in Solar Products
In solar lighting systems, the battery is charged during the day and discharged at night.
This model is widely used because:
- stable discharge performance under daily cycling
- compatible with most 3.7V–12V solar system designs (in pack form)
- suitable for long-term outdoor use when properly assembled
For small solar lighting systems, 18650 cells are often used inside custom battery packs (e.g. 3S2P, 3S3P) depending on voltage requirements.
Battery Pack Use (OEM Application)
This cell is mainly used as a building block for battery packs.
Common configurations include:
- 2S / 3S for low-voltage systems
- 3S2P / 3S3P for 12V solar lighting systems
- Higher parallel groups for extended runtime products
Because of this, consistency between cells is important for pack performance.
Performance in Real Use
In actual applications, performance depends more on usage conditions than lab numbers.
This battery is typically used in:
- daily charge and discharge cycles
- moderate power discharge devices
- outdoor or semi-outdoor environments (in packs)
For OEM buyers, stability across batches is often more important than peak specifications.
Quality & Selection Notes
When choosing 18650 cells for bulk or OEM use, buyers usually focus on:
- batch consistency
- discharge stability
- cycle life under repeated use
- compatibility in battery pack assembly
For mass production, cells are usually tested and matched before pack assembly to ensure balanced performance.
OEM & Bulk Supply
This product is suitable for:
- battery pack manufacturers
- solar lighting factories
- OEM electronics producers
- wholesale distributors
We support bulk supply and can match different project requirements based on application and pack design.
FAQ
Is this true 2200mAh ICR 18650 cell or nominal rated?
It’s enough capacity 2200mAh cell at 3.7V nominal, 4.2V fully charged, tested for stable output under normal load.
What is application the 18650 battery usually used for?
Commonly used is small electronics, LED lighting, backup power, handheld tools, and custom battery packs where steady discharge is needed rather than high current.
