Description

Tenergy T4s Intelligent Universal Battery Charger + 4 x Samsung 18650 35E 3.6V 3500mAh Lithium-Ion Rechargeable Batteries (Protected Button Top) combines an intelligent four-bay universal battery charger with four high-capacity Samsung 35E lithium-ion rechargeable batteries. Each battery provides 3.6V rechargeable power and 3500mAh capacity, featuring a raised positive button-top terminal and integrated protection circuitry. This charger and battery bundle offers a convenient rechargeable power solution for compatible portable lighting, electronic instruments, and equipment designed to accept protected 18650 lithium-ion batteries.

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 LED indicators display charging progress, while automatic charge completion detection, reverse-polarity protection, and short-circuit protection help manage the charging process. 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 Samsung INR18650-35E 3.6V 3500mAh lithium-ion rechargeable batteries with protected button-top construction. Samsung's underlying 35E cell specification provides a minimum standard discharge capacity of 3350mAh, 4.2V charging voltage, 1700mA standard charging current, 2000mA maximum charging current, 2.65V discharge cut-off voltage, and 8A maximum continuous discharge current. The underlying cell measures up to 65.25mm in length and 18.55mm in diameter, with a maximum weight of 50g. The finished protected button-top battery may be longer and heavier because of its raised positive terminal and integrated PCB protection. Actual protection thresholds and current limits depend on the installed PCB. Before installation, verify the equipment's voltage, battery compartment dimensions, button-top contact requirements, and protection-circuit requirements. These rechargeable lithium-ion batteries are not replacements for 1.5V AA batteries, 3.2V LiFePO4 batteries, or nonrechargeable lithium batteries.
