Description

18650 Lithium Ion Battery is a popular battery technology in recent days. Due to its light weight (than lead acid), smaller size, maintenance free and higher capacity than lead acid batteries it is used in many portable applications. The BAK 18650 Lithium Ion Battery is 3C Rated discharge current and it is suitable for high discharge applications. The advantage of Lithium Ion Batteries is avoids Pukert effect that produces less energy before voltage drop in lead acid batteries, Lithium battery provides almost constant power during heavy discharge applications. Energy and Range: Comparing the two chemistries side-by-side, lithium ion achieves an energy density of 125-600+ Wh/L versus 50-90 Wh/L for lead acid batteries. The another great advantage of lithium batteries are charging time, Lithium Batteries are able to charge very faster than Lead Acid Batteries, hence it is suitable for Solar Applications as you can harvest more energy when sun shines. It eliminate the bottleneck of storing more energy when it is available.

Advantages of Lithium Ion Battery over Lead Acid Batteries:

• Maintenance Free (less or no maintenance than Lead Acid batteries like acid topup, etc)
• Rapid Charging
• Less weight and Space
• Long Cycle Life

Applications:

Lithium batteries are used for a long time in our Mobile Phones, Electric scooters and bikes, hoverboards, and wheelchairs, etc. But in recent years, the use of lithium-ion batteries has expanded, and they’ve found a home in RVs, boats, and many types of solar applications.

Important:

1. Never completely discharge the Li-ion battery ( below 2.5V under load ).
2. Charge fully to 4.2V before first use.
3. Never attach any metal moving part |magnet| to the top-positive or the bottom-negative battery contact.
4. Never use force to install (insert) Li-ion battery.
5. Do not use old and new battery cells together.
6. Do not expose to heat.
7. Do not short (connect) positive (top), and negative (bottom) battery terminals (contacts).
8. Keep battery that is not in use in the plastic holder (or any insulating [plastic] container).
9. Do not charge a battery over 4.22V (another reason to use a high-quality battery charger).
10. Don’t charge unattended.
11. Do not store your li-ion batteries fully charged (for an extended period of time).
12. Store in cold and dry place at approximately 3.7V (storage charge).
13. After the battery is discharged-don’t leave it discharged=>charge it as soon as possible
14. The user should have enough knowledge on Li-Ion rechargeable batteries: in discharging, charging, assembly, handling, and proper Li-ion battery storage before use.
