LiitoKala Lii-34B-JT 18650 3400mAh Battery

Liitokala presents the LiitoKala Lii-34B-JT 18650 lithium-ion battery cell with a nominal capacity of 3400 mAh. This battery belongs to the NCR subtype (NCA — lithium nickel cobalt aluminum oxide) and is designed for devices with moderate current consumption, where high capacity and long lifespan are important.

The Lii-34B-JT model is one of the manufacturer's bestsellers due to its optimal balance of capacity, internal resistance, and price. Batteries of this subtype do not have a protection circuit (unprotected), have a button top positive contact, allowing two cells to be installed in series in battery compartments to power, for example, LED flashlights.

Chemistry and Compatibility

The LiitoKala Lii 34B-JT 18650 is an NCA/NCR cell, comparable in characteristics to the Panasonic NCR18650B: similar internal resistance and slightly greater capacity variability. At the same time, LiitoKala products are usually more affordable. The actual operating capacity in tests ranged from 3200-3400 mAh (discharge-charge test results showed 3200-3350 mAh).

Electrical Characteristics and Testing

Testing was conducted with a charge-discharge cycle using a LiitoKala Lii-500 charger in 500 mA mode, which confirmed the stated capacity within 3200-3350 mAh. The average internal resistance value, when monitored with a YR1035+ device, was about 29-35 mOhm. A possible 10-15% reduction in actual capacity under increased loads should be considered; therefore, it is not recommended to operate this cell at high currents.

Application

The battery is suitable for powering household appliances: remote controls, photographic and video equipment, gaming consoles, alarm systems, portable LED flashlights, and other devices requiring a reliable, high-capacity power source.

Advantages

• High capacity in the 18650 size (approximately 3200-3400 mAh).
• Low internal resistance (approximately 29-35 mOhm).
• Button top positive contact for convenient installation in battery compartments.
• Better cycle life compared to some other chemistries and competitive cost.

Recommendations and Operating Rules (Unprotected Li-ion)

• Do not reverse polarity.
• Ensure the charge level does not drop below 2.5 V.
• Do not charge above 4.2 V.
• Keep out of reach of children.
• Store away from sources of fire and heat.
• Do not short-circuit contacts.
• Avoid contact with moist environments.
• Store at temperatures not exceeding 45°C.
• For long-term storage, perform several charge-discharge cycles to restore capacity.
• Use only chargers designed for Li-ion batteries for charging.
