LiitoKala Lii-34B 18650 3400mAh Battery

The LiitoKala Lii-34B 18650 3400mAh battery is a high-capacity lithium-ion cell in the 18650 form factor, manufactured by Liitokala. Its chemical composition belongs to the NCR (NCA, lithium nickel cobalt aluminum oxide) subtype. The battery has a flat top contact and is supplied without built-in protection.

The LiitoKala Lii-34B is positioned as a high-efficiency energy storage device: it does not belong to the high-current INR/IMR types with manganese chemistry, but it offers increased capacity and a long life cycle compared to many other 18650 cells. The Lii-34B is one of the most popular high-capacity batteries in the manufacturer's lineup due to its balanced price-to-quality ratio.

The manufacturer's stated capacity ranges from 3200–3400 mAh, and during independent testing on a LiitoKala Lii-500 intelligent charger in charge-discharge-charge mode at 500 mA, the actual capacity was found to be in the range of 3250–3350 mAh. This makes the Lii-34B comparable in characteristics to the Panasonic NCR18650B and suitable for powering most household and professional devices.

Typical applications for the LiitoKala Lii-34B battery include LED flashlights, photo and video equipment, remote controls, gaming consoles, alarm systems, metal detectors, and other devices requiring a high-capacity 18650 power source.

Technical Features and Testing Results

Actual capacity: 3250–3350 mAh (based on Lii-500 test results). Internal resistance: average value of 29–32 mOhm, recorded with a YR1035+ device. Under increased load, a 10–15% reduction in available capacity is possible, so to preserve the cell's lifespan, it is recommended to avoid excessively high discharge currents.

Advantages

The LiitoKala Lii-34B stands out for its increased actual capacity, low internal resistance, and affordable price. The combination of these properties makes it one of the best choices in the 18650 size for applications where long operating time and daily reliability are important.

Safety Precautions

• Do not reverse polarity

• Do not discharge below 2.5 V

• Do not overcharge above 4.2 V

• Keep out of reach of children

• Do not keep near sources of fire and heat

• Never short-circuit contacts, avoid contact with water

• Store at temperatures not exceeding 45°C

• For long-term storage, several charge/discharge cycles may be required to reach full capacity

• Use only chargers designed for Li-ion batteries for charging

The LiitoKala Lii-34B 18650 battery is an optimal choice for users seeking high capacity and durability in a standard 18650 form factor. Thanks to its test-confirmed actual capacity and low internal resistance, this cell is suitable for a wide range of applications, but requires adherence to basic safety rules: correct polarity, voltage control during charging and discharging, avoidance of short circuits and thermal exposure, and the use of compatible chargers.
