18650 batteryProduct parameters:18650 li-ion rechargeable battery voltage:3.6V capacity: *No memory effect, recharge up to 1000 cycles *Quality guarantee a year brand new Package included:8x18650 li-ion rechargeable battery Suitable for Used in all kinds of toys, it can use Flashlight Dear friends Thank you for purchasing our products.
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. What is a cell in a battery?
A cell refers to a single anode and cathode separated by
electrolyte used to produce a voltage and current. A battery can be
made up of one or more cells. A single AA battery, for example, is
one cell.
2. What is difference between battery and cell?
A cell is known to be a single unit device that tends to convert
the chemical energy into electric energy. A battery generally
consists of a group of different cells. Depending on what types of
electrolytes are used, a cell can be either of reserve, wet or dry
kinds.
3. What is the most common battery cell?
The most common type is the 18650 cell, which is a cylindrical cell
that is 18mm in diameter and 65mm long. These cells are often used
in laptop batteries and other high-powered applications. Another
popular type of lithium-ion cell is the 21700 cell, which is
slightly larger than the 18650 cell.
4. What is a 18650 battery cell?
An 18650 battery is a rechargeable lithium-ion battery. They tend
to have a nominal voltage of 3.6V and range in capacity from
1800mAh to 3600mAh. In all honesty, the name of the 18650 isn't
particularly inventive. The 18 is for the 18mm width of the battery
and the 65mm is for the length.
