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. How many times can a 18650 battery be recharged?
Most 18650 cells are rated for between 300 and 500 cycles. That means your cell can charge up to 4.2 volts, and discharge down to 2.5 - 2.8 volts, a maximum of 300 to 500 times without too much much loss in performance.
2. How do I keep my lithium-ion battery healthy?
Charge or discharge the battery to approximately 50% of capacity before storage. Charge the battery to approximately 50% of capacity at least once every six months. Remove the battery and store it separately from the product. Store the battery at temperatures between 5 °C and 20 °C (41 °F and 68 °F).
3. What are the sizes of lithium battery cells?
Lithium-ion cells come in three basic form factors: cylindrical, prismatic (or brick-shaped), and the flat rectangular shape of lithium-polymer cells. The standard formats for metal-encased cylindrical cells are 18650 (18 mm in diameter × 65 mm tall), 21700 (21 × 70 mm), or 26650 (26 × 65 mm).
4. What is the most common lithium cell size?
Lithium-ion cell sizes
The most common lithium-ion cell is the 18650 (the numbers define the physical dimensions and shape as follows: 18mm in diameter, 65mm long and the 0 means it has a round cross-section) which is due to its widespread use in laptop battery packs.
