The labeled capacity of unscrupulous manufacturers cannot be trusted. If you want to know the actual capacity, you need to use professional testing equipment for charging and discharging testing. Therefore, most people do not know the specific capacity size when they get it, and it is easy to be deceived by the seller. If the buyer does feel that there is something wrong with the capacity, they can ask the supplier to provide a testing report or choose a third-party professional testing agency to report.
The price of 18650 lithium batteries is directly proportional to the size of the capacity. The larger the capacity, the greater the energy ratio, and the more raw materials used, so the price will be more expensive. The general price is 10-30 yuan per unit. It is worth noting that many buyers have a misconception that high capacity leads to a large actual discharge current, but this is the opposite.
18650 lithium batteries are generally divided into capacity type and rate type. Capacity type mainly reflects high capacity, but the discharge current is generally lower than 1C and the current is relatively small; The rate type can discharge large currents, but its capacity is low and its usage time is not long, which is similar to not having both fish and bear's paws.
The capacity of 18650 lithium battery is the main selling point of lithium battery manufacturers. In addition, the brand of 18650 lithium battery cell with the same capacity is also a factor affecting the price. Generally speaking, the price of imported brands is higher than that of domestic brands of the same type. As mentioned earlier, the main factor determining the capacity of 18650 lithium battery is also the raw material structure. Therefore, from the perspective of positive pole, the prices of lithium cobalate, lithium manganate, ternary materials and Lithium iron phosphate will be different.
