Battery Capacity and mAh. Battery capacity is measured in milliamp hours (mAh). This figure tells you how much charge a battery can hold. A 2000mAh battery can provide 2000mA of current for one hour before it runs out. The mAh rating impacts the runtime of your device. Higher mAh generally means longer use, but it also affects weight and size.
I bought some 9800 mAh Li ion 18650 batteries on eBay and tested them with my genuine SkyRc charger/tester. maximum capacities were between 990 and 1080 mAh each with a sample set of four cells. Yes I was hoping for 2500 mAh, but for two dollars you get what you pay for.
When they first came out, 18650 cells had a capacity of around 1200mAh. As the battery chemistry and methods to manufacture the cells advanced, the capacity of the average 18650 slowly increased over time. Eventually, we will have 4.5Ah and even 5Ah+ 18650 battery cells, but that day is unfortunately not today.
Alternatively, the battery can last longer if the current draw is lower. For instance, if the device draws 500mA, the same 3000mAh battery would last approximately 6 hours (3000mAh ÷ 500mA = 6 hours). Higher capacity 18650 batteries can store more charge, resulting in longer runtime for devices powered by these batteries. Part 2.
“3000 mAh” measures the amp hours the battery can provide. A higher number is better. The highest realistically available on an 18650 today is about 4000 mAh, anything higher than that is marketing hype. “Low self discharge” is a good thing. That means it will hold a charge in storage.
Here’s a comparison between high capacity and low capacity 18650 batteries: Greater Energy Storage: High capacity 18650 batteries typically have a larger energy storage capacity, often ranging from 3000mAh to 3500mAh or more. Suitable for High-Drain Devices: High capacity batteries are well-suited for devices with high power demands.
21700 – were designed to be a larger and higher capacity replacement for 18650 batteries. Like the 18650, the 21700 has a nominal voltage of 3.6/3.7V. The 21700 was designed to replace the 18650 in EV battery packs. The capacity of these batteries ranges from about 4,000 to 5,000 mAh.
