Dear friends:
Thank you for purchasing our products.
It’s probably essential to consider when selecting a High Rate 21700 Li-ion Battery. You need to know how much current the device you are trying to power requires before choosing your high Rate 21700 Li-ion Battery. If you select a 21700 Li-ion Battery with a current rating more minor than what you need, you will notice the High Rate 21700 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 21700 Li-ion Batterycurrent ratings. Those terms are continuous discharge rating (CDR) and pulse discharge rating (Pulse).
*** 21700 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. What is the highest capacity 21700 battery?
5500mAh. 21700 batteries are able to reach a maximum capacity of 5500mAh.
2. What is the common name for rechargeable battery?
Lithium-Ion (Li-ion) Batteries. Li-ion is the most common type of rechargeable battery used in portable electronic devices today.
3. What is the life of rechargeable cell?
If charged and not placed into a device, a rechargeable battery can last up to seven years. The rate of natural discharge will be relatively slow. If fully charged and placed into a device, the battery life can vary by how often it's used and how much power is required by the associated electronics.
4. Do rechargeable batteries lose charge if not used?
Many ready for use rechargeable batteries lose their capacity when not in use. That's why you still will have to charge them before using them. This phenomenon is called self-discharge.
