![]() ![]() At the moment, the maximum capacity of the 18650 battery is 3500 mAh.Ī battery cell with the technical name 18650 has the dimensions and shape of the battery according to the number. That would be like owning a 10 liter water bucket and wanting to fill it with 17 liters of water. A cell's cup only has a certain volume that can be filled with chemicals. Please be careful, a Li-Ion 18650 battery with a running time of 5000 mAh hours, for example, is disproportionately high. You can take a look at our test measurements on our test page before buying Li-Ion 18650 batteries. In the case of the protected cells, you must check whether a no-name cell or one of the brands mentioned above was used as the base cell behind the protected accumulator. So we recommend that you buy a Panasonic, LG, Sony, or Samsung battery. Promising results are obtained from the brands of unprotected cell 18650 batteries. For example, an 18650 battery is ideal for e cigarettes, but regardless of whether you are looking for an original or a replacement battery for your purpose, you are certainly wondering which 18650 batteries are the most powerful. You will find many different battery models in our battery shop. A deep discharge (below 2.5V) or overcharging (more than 4.2V) causes lasting damage to the battery cell and can cause it to malfunction! If you have further questions, either read our FAQ section or come to one of our battery shops! Our experts will advise you so that you are sure to buy the right 18650 battery. The same applies here: A lower voltage of z. In the category of 18650 battery chargers you will find devices with which you can safely charge your new energy storage device. ![]() The 18650 Li-Ion battery only reaches around 95% of its nominal capacity, but in most cases this is sufficient. only 4.15 volts, the battery guarantees an extremely long service life. A higher charging voltage would overcharge the cell, with a lower one of e.g. That is simply wrong! A fully charged 18650 battery has a maximum voltage of 4.2 volts. Many think that a battery with a specified nominal voltage of 3.6 volts must not be replaced with a 3.7 V battery. The nominal voltages of a 18650 lithium battery 50 ° C, charging at room temperature is optimal. The operating temperature during discharge is from -20 to 60 ° C for most cells, but charging the 18650 battery only works from 0 ° C to approx. On this page we test lithium ion batteries of the type 18650 from various manufacturers such as Panasonic, Samsung and Sony and give ratings so that you can buy the 18650 batteries you need online in our battery shop. For everyone who is interested in the actual capacities and maximum discharge currents, we have created a page with a battery 18650 test. As a rule of thumb you can note the following dependency: "The higher the nominal capacity, the lower the maximum discharge current". For example, the Panasonic NCR18650BF must not be connected in parallel more than four times. This is just one example of why not every cell is suitable for every application. Many e-vapers can confirm this with the battery of their e-cigarette. a fast and high power output is almost impossible here. The charging current must also be taken into account here! The appropriate data sheet and technical information must display or specify these parameters, which is why you should study this data carefully.Ī special feature: the battery with PCB always has a much greater internal resistance, i.e. And, to put it simply, some of the protective electronics can withstand less current than the cell itself. Li Ion batteries: What should you watch out for when buying a battery online?īatteries such as a 18650 Li-ion battery and battery packs with protective electronics (PCB) have a higher internal resistance. ![]()
