What is the capacity of 18650 lithium-ion battery?

Due to the18650 battery fixed size, its maximum capacity has been attracting the attention of many practitioners. The technology of each manufacturer has improved in recent years, and the capacity also increases. Samsung, Panasonic, LG, SONY, Toshiba can be more than 3600 mAh, but the best stability consistency is 2600 ~ 3000 mAh. If you want to make battery pack, you had better don't use the highest capacity. Neither the price, nor the service life of the battery pack for battery pack is a bargain. So battery with larger capacity is not always the best.

Battery pack need to customize according to the product, if the product belongs to high-grade, the battery can choose big brands imported batteries (original), because there are many small batteries factory domestic battery have been empty mark, if the price is too sensitive, such as strong light flashlight products price competition is larger), domestic formal manufacturers can choose 2200 mAh ~ 2600 mAh batteries or lower 1500 + capacity. Most applications have different current and time requirements, so most of the power supply batteries in the battery pack, in the choice should consider choosing the consistency of batteries, battery stability, safety, and these measures are very important.

It is worth noting that many buyers will have a misunderstanding, think high capacity, the actual discharge current will be very big, but that the opposite is true:18650 lithium batteries generally divided into capacity and ratio, capacity model mainly reflects the large capacity, but generally less than 1 c discharge current, current is smaller; Ratio can be large current discharge, but the capacity is low, use time is not long. It's similar to not have your cake and eat it.

How do you know 18650The lithium battery the actual size? Unscrupulous manufacturers labelling capacity but can't believe that, if you want to know the actual capacity, you'll have to charge and discharge through the professional test testing equipment testing, so the average person on the also don't know the specific size, it is easy to be deceived by the seller, if the buyer really feel capacity have something, can ask the supplier to issue test report or choose a third party professional testing institutions.

The price and capacity of 18650 lithium battery price are proportional. The larger the capacity, the larger the energy ratio is. The more raw materials you use, the more expensive is. The average price is 10 ~ 30 yuan/battery.
