Description

Tenergy T4s Intelligent Universal Battery Charger + 4 x 18650 3.6V 2200mAh Lithium-Ion Rechargeable Batteries combines a versatile four-bay intelligent battery charger with four 18650 lithium-ion rechargeable batteries. Each included battery provides a nominal voltage of 3.6V and a rated capacity of 2200mAh. This convenient charger and battery bundle is designed for compatible electronic equipment requiring rechargeable 18650-format lithium-ion batteries and offers a practical solution for charging, maintaining, and reusing rechargeable cells.

The Tenergy T4s Intelligent Universal Battery Charger features four independently controlled charging slots, allowing compatible rechargeable batteries to be charged individually or simultaneously. Its microcomputer-controlled charging system supports lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), nickel-metal hydride (NiMH), and nickel-cadmium (NiCd) rechargeable batteries. Individual yellow LED indicators display charging progress, while automatic charge completion detection, reverse-polarity protection, and short-circuit protection help manage charging. The charger accepts AC 100-240V, 50/60Hz or DC 12V input and provides output voltages of 4.2V, 3.6V, and 1.48V for supported battery chemistries. Maximum charging current is 425mA per slot with four occupied slots or 850mA per slot with one or two occupied slots.

The bundle includes four 18650 3.6V 2200mAh lithium-ion rechargeable batteries, providing rechargeable performance, high energy density, and no memory effect. The 18650 designation describes a cylindrical battery format nominally approximately 65mm long and 18mm in diameter; actual finished-cell dimensions depend on the specific battery construction, terminal style, and any added protection circuitry. Standard 3.6V lithium-ion rechargeable cells generally use constant-current/constant-voltage (CC/CV) charging with a 4.2V full-charge voltage, subject to the supplied battery manufacturer's specifications. Before installation, verify battery dimensions, terminal configuration, discharge-current requirements, and protection-circuit requirements. These batteries are not substitutes for 1.5V AA batteries, 3.2V LiFePO4 batteries, or nonrechargeable lithium batteries.
