t’s probably essential to consider when selecting a High Rate 18650 Li-ion Battery. You need to know how much current the device you are trying to power requires before choosing your high Rate 18650 Li-ion Battery. If you select a 18650 Li-ion Battery with a current rating more minor than what you need, you will notice the High Rate 18650 Li-ion Battery overheating as it is working beyond its ability to keep up. You should also know two terms that are discussed in the high Rate 18650 Li-ion Batterycurrent ratings. Those terms are continuous discharge rating (CDR) and pulse discharge rating (Pulse).
*** 18650 Battery Care Tips ***
- Never fully discharge a Li-Ion battery (less than 2.5V load).
- Fully charge to 4.2V before first use.
- Never forcefully install (insert) the Li-ion battery.
- Do not use old and new batteries at the same time.
- Use only a top-notch battery charger.
- Do not expose to warm environment. Try not to short (connect) the positive (top) and negative (bottom) battery terminals (contacts).

FQA:
1.Why is 18650 so expensive?
They cost more than your standard alkaline batteries because they are suitable for high-drain devices and have a greater capacity. As the technology improves, the cost of manufacturing these batteries will decrease, and in return, the cost at retail prices will decrease, too, for the average consumer.
2.Can 18650 batteries be replaced with AA?
No, you cannot replace (or use) 18650 batteries in place of AA batteries. The difference in their capacity and nominal voltage makes replacing them challenging, even if you connect AA batteries in series to increase their voltage.
3.Are all 18650 batteries the same?
18650 is not a standard battery. They are not built in the same way, or have different tasks in mind. The most important characteristic to consider when looking at an 18650 battery is the continuous discharge rating (CDR), also known as the ampacity.
4.How do I know if my 18650 is still good?
Self Discharge Test
So, that's why when we are testing 18650 cells, we let the cells sit for a full week once they are fully charged. If the voltage of any cell drops by more than 0.1v during that time, the cells should be discarded.
