ULTRALAST

ULTRALAST is a brand associated with consumer and industrial battery products, with a catalog that includes 18650-size lithium-ion rechargeable cells and dedicated chargers. The line is centered on the 18650 form factor, a cylindrical cell size measuring 18 mm in diameter and 65 mm in length. These cells are widely used in portable electronics, flashlights, power tools, backup power systems, and battery packs where a rechargeable 3.7V DC nominal voltage source is required. ULTRALAST products in this category are identified by manufacturer part numbers such as UL1865-26-1P, UL1865-34-1P, UL1865-26-2P, UL1865-34-2P, ULLIONCHG, and UL1865K-26. The product family includes single cells, multi-pack configurations, and charger units or kits designed specifically for 18650 lithium-ion cells. These items are intended for integration into devices and systems that accept the standard 18650 footprint, including portable instrumentation, test equipment, handheld tools, medical devices, and backup power assemblies. The chargers are configured for lithium-ion chemistry and the 18650 cell size, providing a matched charging solution for the corresponding cells. 3G Electric supplies the ULTRALAST line as part of its industrial-equipment distribution catalog. The company is headquartered worldwide and serves customers globally, with logistics support for international delivery. For technical buyers, 3G Electric provides access to multiple SKUs within the ULTRALAST 18650 battery and charger range, allowing procurement of individual cells, multi-packs, and charging accessories from a single source. The product data available includes manufacturer part numbers, battery chemistry, voltage ratings, and compatible battery sizes, which supports specification matching and cross-referencing during the procurement process. 3G Electric does not manufacture ULTRALAST products; it distributes them. Buyers should refer to the manufacturer's documentation for detailed performance characteristics, cycle life, discharge rates, and safety handling requirements. The 18650 format is a standardized cell size, but electrical characteristics can vary between specific models and part numbers. When selecting a ULTRALAST cell or charger, verify that the nominal voltage, chemistry, and physical dimensions match the requirements of the target device or battery pack. The chargers in this line are designed for 18650 lithium-ion cells and should not be used with other battery sizes or chemistries unless explicitly stated by the manufacturer. 3G Electric's role is to make these products available to industrial and commercial buyers, with the SKU-level detail needed to confirm fit and function before purchase. For applications requiring battery packs, backup systems, or replacement cells in portable equipment, the ULTRALAST 18650 range offers a defined set of options. The availability of both single cells and multi-packs supports different inventory and replacement strategies. Charger kits provide a combined solution for users who need to maintain a stock of charged cells. All products are supplied as described by the manufacturer's part numbers and specifications. 3G Electric can provide quotes and logistics support for global delivery, and buyers are encouraged to confirm part numbers and quantities against their specific application requirements.

Frequently asked questions

Common questions about ULTRALAST from 3G Electric.

What is the nominal voltage of ULTRALAST 18650 batteries?

ULTRALAST 18650 lithium-ion batteries listed in the 3G Electric catalog have a nominal voltage of 3.7V DC. This is the standard nominal voltage for lithium-ion cells in the 18650 form factor. Actual charged voltage will be higher (typically 4.2V for full charge) and cutoff voltage lower, depending on the device and charger. Always confirm the voltage requirements of your equipment before substituting or installing cells. The 3.7V DC rating applies to the specific part numbers UL1865-26-1P, UL1865-34-1P, UL1865-26-2P, and UL1865-34-2P as listed.

What charger should be used with ULTRALAST 18650 cells?

ULTRALAST offers chargers designed specifically for 18650 lithium-ion cells, including part numbers ULLIONCHG and UL1865K-26. These chargers are configured for the 18650 size and lithium-ion chemistry. Using a charger intended for a different cell size or chemistry can damage the cell or create a safety hazard. Match the charger to the cell's chemistry and form factor. The UL1865K-26 is a kit that includes charging capability for 18650 cells. For detailed charging parameters such as charge current and termination method, refer to the manufacturer's documentation for the specific charger model.

Are ULTRALAST 18650 batteries available in multi-packs?

Yes. The ULTRALAST line includes 2-pack configurations, such as part numbers UL1865-26-2P and UL1865-34-2P. These contain two 18650 lithium-ion cells with a nominal voltage of 3.7V DC. Single-cell options are also available, including UL1865-26-1P and UL1865-34-1P. Multi-packs are useful for maintaining matched sets of cells for devices that require more than one cell, or for keeping spare cells on hand. When using multi-cell configurations, ensure cells are matched and charged together as recommended by the device manufacturer.

What devices can use ULTRALAST 18650 cells?

ULTRALAST 18650 cells are suitable for devices that accept the standard 18650 form factor and require a 3.7V DC lithium-ion rechargeable battery. Common applications include portable electronics, flashlights, power tools, portable instrumentation, test equipment, handheld tools, medical devices, and backup power systems. The 18650 size is widely used, but device compatibility depends on physical fit, voltage, capacity, and discharge characteristics. Always verify that the cell's specifications meet the device requirements. Do not use a cell in a device unless the device is designed for that cell's chemistry and voltage.

Does 3G Electric ship ULTRALAST products internationally?

3G Electric is headquartered in Singapore and provides logistics support for worldwide delivery. ULTRALAST batteries and chargers can be shipped to international destinations, subject to applicable shipping regulations for lithium-ion batteries. Lithium-ion cells are classified as dangerous goods for transport, and shipping methods, packaging, and documentation must comply with international and local regulations. Buyers should confirm shipping eligibility and any restrictions for their destination. 3G Electric can provide quotes that include logistics considerations for the order.

How do I identify the correct ULTRALAST replacement cell for my equipment?

Identify the required cell size, chemistry, and nominal voltage from your equipment's specifications or the existing battery label. ULTRALAST 18650 cells are 18 mm diameter by 65 mm length and 3.7V DC lithium-ion. Match the manufacturer part number to the product listing: UL1865-26-1P and UL1865-34-1P are single cells; UL1865-26-2P and UL1865-34-2P are 2-packs. If your device uses a battery pack, confirm the pack configuration and whether individual cells can be replaced. For chargers, use ULLIONCHG or UL1865K-26 with 18650 lithium-ion cells only. Consult the equipment manual for any additional requirements.
