It can affect the performance and life of the battery. For the 18650 2800mAh, it is best to use and store the battery within the recommended temperature range: 20°C and 60°C discharged, 0°C to 45°F.
Higher total cell capacity.
The battery capacity (measured in milliamp-hours or mAh) of 18650 cells is limited to a maximum of around 3600mAh because of its size.
However, the 21700 battery is able to reach a maximum capacity of 5000mAh – a 42% increase.
For flashlight or e-cigarette users, that means up to 142% of the previous run time on a single charge, which is invaluable for heavy users. And since they’re still less than 1″ in diameter, flashlights using these batteries can still fit in standard 1″ weapon mounts and holsters!
When choosing 18650 2800mAh battery, you can consider the following aspects:
Brand selection: choosing 18650 batteries from well-known brands usually ensures high quality and performance. Recommended brands include LG, Samsung, Panasonic and Sony, etc.
These brands have a good reputation and high quality products in the market.
Capacity selection: capacity is an important indicator of battery life. 18650 batteries generally have a capacity of between 2000mAh and 3500mAh. 2800mAh batteries can provide longer usage time and are suitable for devices that need to run for a long time
Safety: Make sure the battery is safe when purchasing. Avoid buying batteries with falsely labeled capacity, especially those with a claim of more than 3,000mAh, which is likely to have a false labeling problem. The highest capacity battery available on the market is Panasonic's 3400mAh, while the capacity of domestic batteries is generally between 2200mAh and 2800mAh
Continuous discharge capacity: the continuous discharge capacity is expressed in C. For example, the capacity of an 18650 battery is 2800mAh, the continuous discharge capacity is 0.5C, then the continuous discharge current is 1.4A. A long time more than 1.4A discharge will affect the life of the battery, and may even lead to overheating, combustion or explosion and other dangers.
Purchase channel: Try to buy through regular channels.
Purchase channels: Try to buy batteries through regular channels to ensure product quality and safety. Avoid purchasing dismantled batteries, as these batteries may be close to being obsolete and there is no need to waste money!
