You heard that right some batteries come with a warranty! Protected 18650 batteries are the way of the future.
Also, some companies even offer a warranty for their batteries. That is a great thing because no one wants their battery to explode or melt! You really want to pay attention to the specifications when purchasing a 18650 battery. Crazy! The little circuit board also helps protect against overheating. They have a tiny protection board installed inside them. These batteries are created to include overcharge protection and over discharge protection. The exact runtime length depends on the product you are using your battery in. They will both give you the same amount of power however, the 3500 will run a bit longer. Say you have one ARB-L18-2600 mAh 18650 battery and one ARB-L18-350 battery. The higher the milliamps, the longer the runtime.
Milliamp is a measurement used for electric current output. Having fully charged back up batteries is always a good thing. Good to know, right? If you have spare 18650 batteries that do not get a lot of regular use, I would suggest charging them at least once every three months. The higher the voltage, the longer your 18650 lithium ion battery will last. I would suggest always keeping your 18650 lithium ion batteries charged over 3.5 volts to maximize your usage. You know how back in the "old days," we were taught to let a rechargeable battery go completely dead before -recharging it? Well, that is definitely not the case anymore. 18650 batteries can have anywhere from 300 to 500 charging cycles, which is insane! It usually takes about 3 hours to charge a 18650 lithium-ion battery fully. These batteries are not only used in flashlights, but also in: power tools, electric vehicles, vaporizers, cameras, laptops, and more! A High Drain battery basically means the battery gives out a larger amount of current than regular batteries. They get their name from their size: 18mm by 65mm. 18650 batteries are lithium-ion batteries. Have you heard of 18650 batteries? I stumbled upon and learned they use a specific battery in many of their lights. Needless to say, that has caused much safer batteries to be produced. Can you overcharge a lithium ion (Li-ion) battery? Yes! I do not know if you guys remember, but a few years back in 2016, there was a period of time when Samsung Galaxy Note7 phones were exploding! They were exploding because of a defect in the phones tied to the lithium ion batteries. Can you over charge a lithium battery? No, you cannot because they are not rechargeable. In the midst of my online search, I learned that lithium batteries are not rechargeable, but lithium-ion (Li-ion) batteries are rechargeable.
Which, if you think about it, lithium ion batteries are still relatively new and evolving each year. Lithium-ion batteries were first invented by an Exxon chemist called M. Crazy right? Not only that, but there are rechargeable and non-rechargeable versions. These batteries help power a wide variety of products from cell phones to Hybrid Vehicles. Did you know there are several different varieties of Lithium ion batteries? For example, Lithium-Manganese Oxide, Lithium-Nickel Manganese Cobalt Oxide, Lithium-Iron Phosphate, Lithium-Titanate, and Lithium-Cobalt Oxide.
