Package Includes:

• 1 x 3.7v 2500mah 18650 Li-Ion Battery

Specifications:

1. What is an 18650 Battery?

• An 18650 battery is a cell that's 18mm x 65mm in size. The name, 18650, refers exclusively to the size of the lithium-ion battery cell, but there can be minor variations even here.
  They offer the performance of a lithium-ion cell, a capacity in the range of 1800mAh to around 3500mAh, and an output of 3.7 volts. They're used in a huge range of devices from laptops to laser pointers, and camera accessories like gimbals and sliders.

2. How to connect 18650 Li-Ion Battery?

• It is very easy to use the cell in any circuit just solder the wires on the terminals or use 18650 battery holders to easily replace the used cells

3. What are the precautions to be taken while working with Li-Ion batteries?

• Care must be taken while handling Li-ion batteries as they are volatile and inflammable and should not be handled roughly and punctured. Also, don’t overcharge and discharge beyond a certain point as gases accumulated inside might result in explosions and fire. So always use the Protection board while using Li-Ion cells.

4. How long does it take to charge a 18650 battery?

• The amount of time that a battery takes to charge can vary depending on the brand of battery and the capacity of the battery. The capacity of a 18650 battery is determined by something called the milliamp level, which can be abbreviated as mAh. The milliamp level of 18650 batteries typically ranges from around 2300 mAh to a maximum of 3600 mAh. Since a higher milliamp level indicates a higher capacity and longer run time, this also means that a 3500 mAh 18650 battery will take longer to charge than a 2300 mAh battery. For example, a 2600 mAh 18650 battery may take an estimated 4 hours to charge.

5. How long do 18650 batteries last?

• The amount of time that a 18650 battery can last is dependent on a lot of factors. The amount of time they are used, how often they are recharged, and their general care are all important factors that play into the longevity of your 18650 batteries.
  The best practice for getting the maximum life from your battery is to use it until it is at about 50% and then recharge it.

6. How many times can a 18650 battery be recharged?

• Most 18650 cells have a cycle life of 300 to 500 cycles. That means your cell can charge to 4.2 volts and discharge to 2.5 - 2.8 volts a maximum of 300 to 500 times without experiencing significant performance loss. When a 18650 cell reaches the end of its useful life, its performance degrades abruptly and rapidly.

7. Is the 3.7V 2500mAh 18650 Li-Ion Battery Original and Genuine?

• Yes, the 3.7V 2500mAh 18650 Li-Ion Battery available at Robocraze is sourced from verified suppliers to ensure authenticity and consistent performance.
