E Cig Rechargeable Battery 3.7v Lithium Polymer Battery Cells 690mAh 5.5A

FULLYMAX 961941 690mAh 5.5A 3.7V Long Cycle Life lithium ion polymer rechargeable lipo battery

Automatic batteries were once the first type of e-cig new vapers would try. Most cigarette-like vaping batteries have automatic operation, yet the performance is generally better with manual options. But what do these terms mean?

When you inhale on a cigalike with an automatic battery, a sensor detects the rush of air and activates the battery. However, with a manual battery you depress the button to activate the battery. This might seem less convenient but it’s something you get used to really quickly, and it gives you more control over your draw.

Nowadays some devices come with both auto and manual operation. This is great if you are new to vaping, as you can see which one suits you best.

Storage with fully charged status at room temperature (23±2℃)for three months, the OCV is higher than 4.155V, the self discharge is at leading level among the industry.

Disposable / Twice E-cig battery C rate performance can match market demand.

polymer (Li-Po) batteries.
In general, the diferences lie in the materials made of the positive & negative terminals, the area density design, the electrolyte ingredient, the septum data and the density of inside pieces.

When a Li-Po battery is made, five main aspects should be considered carefully:

(1). Battery Pack should have suficient strength, so that the polymer battery inside could be efectively protected from mechanical shocks;

(2). The polymer cell should be fixedto the battery pack onits large surface area - no cell movement in the battery packshould be allowed;

(3). No sharp edge components should be inside the packcontaining the polymer battery, and meanwhile, suficient insulation layer between wiring and the cell should be used to maintain multiple safety protection;

(4). Ultrasonic welding is recommended for polymer tab connection to obtain low-resistance, high-reliability and light-weight properties;(5). Polymer packs shouldbe designed carefully so that no shear force is applied, and also, no heat is generated even when leakage ocurs for mishaps. PCM from electrolyte leakage should be isolated as perfectly as posible, and narrow distance between bare circuit patterns should be avoided.

The generated gases include Co, CO2,H2, CH4 and so on. They are not dangerous because of low volume.

Organic solvents easily decompose on the negative electrodes during charging, leading to battery swelling, drop of cell capacity, and unsafety caused by activereaction. The purpose of the formation process is to form a solid layer called the solid electrolyte interphase (SEl), which is electrically insulating yet provides significant ionic conductivity. This interphase prevents further decomposition of the electrolyte after the second charging.
