18650CR-1S-CT Cylindrical 3.6 V 3380mAh Lithium Ion Battery Cell
for Industrial Devices
The Cylindrical 3.6V 3380mAh 18650CR-1S-CT Li-ion Battery is a
industry-standard, high-performance power solution built on the
iconic 18650 form factor—widely recognized for its compatibility,
durability, and energy density. Tailored for both consumer
electronics and small-scale industrial applications, this battery
balances generous capacity with stable output, making it a go-to
choice for devices requiring reliable, long-lasting power.
Core Performance & Capacity
Operating at a nominal 3.6V (with a safe working range of 3.0V
discharged to 4.2V fully charged), this battery delivers consistent
voltage to match the needs of most mid-power devices. Its 3380mAh
high capacity translates to practical, extended runtime: it can
power a portable LED work light for 12–15 hours, a handheld gaming
console for 6–8 hours of play, or a small portable charger (power
bank) to top up a smartphone twice. The 1S (single-cell)
configuration simplifies integration, eliminating the need for
complex voltage regulation in devices designed for single-cell
lithium-ion power.
Standardized Cylindrical Design
As an 18650-format battery (19mm diameter × 69.5mm length), it
adheres to global industry standards, ensuring seamless
compatibility with thousands of devices and battery holders. Its
cylindrical shape enables easy modular assembly—users can connect
multiple batteries in series (for higher voltage) or parallel (for
higher capacity) to power larger systems, such as DIY solar energy
storage kits or electric scooter auxiliary power supplies. The
robust metal casing adds physical protection against impacts and
wear, making it suitable for rugged use in outdoor or industrial
environments.
Enhanced Safety & Durability
Safety is integrated into its design, with a built-in Protection
Circuit Module (PCM) that guards against overcharging,
over-discharging, short circuits, and overcurrent. This prevents
device damage and reduces safety risks, even during prolonged use.
The battery also boasts a long cycle life of over 500
charge-discharge cycles (retaining ≥80% of initial capacity),
outperforming lower-capacity 18650 batteries and reducing long-term
replacement costs. Its wide operating temperature range (-10°C to
60°C) ensures reliability in both cool indoor settings and warm
outdoor conditions.
Versatile Applications
This battery’s adaptability makes it ideal for diverse uses:
- Consumer electronics: Powering laptops (secondary cells), flashlights, digital cameras,
and portable audio players;
- Small industrial devices: Supporting IoT sensors, handheld meters, and emergency backup
lights;
- Outdoor & DIY projects: Fueling camping lanterns, portable fans, and custom robotics
builds.
With a low self-discharge rate (<4% per month), it also works
well as a backup battery, retaining charge for months when stored
properly. Compatible with standard 18650 chargers, it recharges
efficiently—reaching 80% capacity in approximately 2 hours with a
1A charger.
