Description of Battery Li-Ion 3000 mAh 3.7 V LiitoKala HG2 18650 unprotected, pack: 5 pcs.

Liitokala Li-Ion battery (HG2-18650) with flat positive contact, no protection board. Battery capacity - 3000 mAh. Used in devices equipped with their own charge / discharge controller. As a rule, these are laptop batteries and removable batteries for screwdrivers, vapes, vacuum cleaners, flashlights and other power tools powered by Li-ion battery packs. At a low price, the product has a 100% honest capacity, confirmed by measurements. If used in a device without a controller, the battery may be damaged. Actual battery size: 6.5x1.8 cm. Maximum charge/discharge current 20A. Batteries of this type Liitokala (HG2-18650) among their competitors have high current efficiency, low resistance and affordable price, the combination of these qualities makes them one of the most attractive models among high-current 18650 form factor batteries. Among competitors, this is the most affordable option with real capacity. Compared with Ni-Cd and Ni-MH batteries, Li-ion batteries have higher energy storage density, higher voltage, better storage performance, extended operating temperature range. Liitokala HG2 18650 batteries were tested in the Liitokala Lii-500 smart charger with a charge current of 1A and a discharge current of 0.5A. The capacity was measured during discharge (measurement of the capacity given by the batteries) and the following values ​​were obtained: 3032 mAh, 3024 mAh, 3056 mAh and 2949 mAh. As can be seen from the test results, all batteries reached the capacity declared by the manufacturer, and some even exceeded it. We can also conclude that the capacity of Liitokala Lii-HG2 batteries has a real declared by the manufacturer and low resistance, the average capacity is 2950-3050 mAh. Purpose: For power tools, For electric bicycles, For cameras, For cordless phones, For laptops, For electric scooters, For external batteries, For video cameras, For household appliances, For cars, For UPS, For GPS navigators, For assembling Power Bank, For control panels , for metal detectors, for photo equipment, for medical equipment, for radio-controlled models, for hair clippers

I recommend to buy, the product is of high quality.

I replaced the nickel-cadmium cans in the battery for a screwdriver with lithium. Shurik found a new life, he drills metal. At the same time, the banks have some voltage drop up to the nominal 3.6-3.7 V, but the capacitance is kept

Pros
  • Inexpensive. Delivery is quite fast compared to China
Cons
  • Banks are not the first freshness - subjectively, based on the testimony of a Chinese charger, which measures internal resistance. It also measures the capacitance in charge and discharge. I tested only one jar, which showed the greatest internal resistance. According to the results of measurements in a load of 1A, the capacity turned out to be about 2700 mAh (alas, I didn’t take a picture), 10% lower than declared, therefore 4 stars

The product is good, there are only a few minor flaws.

I've already gone through a bunch ofcomrdless tools - from small electric screwdrivers to 36-volt self-propelled lawn mowers - everything works fine! For any grinders and circulars, it is highly desirable to put them at least 2 in parallel - these tools require high currents, especially when the disk gets stuck in the material. For less voracious gadgets, their power and capacity will be enough for the eyes! Definitely recommend! How even a single-speed screwdriver turns with them can be seen…

Pros
  • Good batteries for the price.
Cons
  • They do not reach the original (LG) in terms of current output - for a long time 10-15a, 20a is better no more than 2-3min.

How could such a bad product be made?

The batteries caught fire in the vape. Which was turned off, they just stood in it. The vape began to smoke, the smell of burning appeared, they quickly sorted it out, thank God there were no casualties. The smell is incredible throughout the apartment. Do not take. Not a safe product.

Pros
  • There is none of them.
Cons
  • Batteries caught fire in a vape

A reliable product, quality is acceptable.

In the nor test mode (charge-discharge-charge, the capacity is calculated when the battery is discharged to the internal load), it showed 2800 mAh, which is slightly lower than the nominal value.

Pros
  • +/- the correct capacity is indicated. Inexpensive.

I am very happy with this purchase, I will advise everyone!

I'll dispel the myth right now. No. This is not LG HG2. This is not an LG sub-brand. This is a copy, but good quality. Original batteries will cost you 2 times more per piece. The capacity indicators are the same (during the first cycle, the discharge / charge is 10% lower, but this is normal). I didn’t manage to check the current, because I don’t want to make a hand grenade out of the battery, but it works fine in vapes and a powerful flashlight.

Pros
  • - Price - capacity - The same internal resistance of the batteries (it can be seen that from one batch)
