The primary battery refers to the battery that can only discharge and is not rechargeable. The secondary battery refers to the rec > Lithium-ion batteries are common in consumer electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses fohargeable battery that can be charged and used in duty-circle operation.
2.What is the cycle life of rechargeable battery?
When a battery experiences a charge an ies are technological evolution from lithium-ion batteries. The primary difference is that the lithium-salt electrolyte is not held in an organic solvent but in a solid polymer composite such as polyethylene oxide or polyacrylonitrile.
The advand discharge, we call a cycle or a period. In the stated charge and discharge principles and the capacity decline before a stated

3.What are the possible resons for the rechargeable battery service life reduction?
1).Charger or charging circuit is not matching to the battery type.
2).Over charge and over discharge.
3).Battery type is not matching to the appliance.
4.What are the possible reasons if the rechargeable battery or rechargeable battery pack can not be charged?
1). The battery is zero voltage or there is battery with zero voltage in the berred to as the delay time and the lowe #`| ( ( Xe| j" j" Y" T" S" T" T" g| j" j" attery pack.
2). There is wrong connection inside the battery pack.

The degree of passivation is a function of storage time, current, temperature during storage, and mechanical aspects. Thus, passivation will usually grow with storage time and temperature. Depassivation can be effected by current flow as well as mechanical shocks, vibration, and temperature cycling. As a rule of thumb a current of 2 A/cm2 of lithium anode surface area will prevent passivation and allow for immediate voltage response above typical application cut-off values. The same can be achieved by daily pulses corresponding to equivalent or slightly smaller average values.
Long Operating Life and shelf life-----The self-discharge of Li/SOCl2 Batteries are extremely low ( less than 2% per year at 20 ), which can support long storage periods and achieve a service life of 10 to 20 years.
Environmentally Friendly-----our batteries are free of heavy metals
Hermetically sealed case-----The hermetically sealed case is essential for the long shelf life and inherent safety of the devices in which the batteries are used. The cover is welded to the can. A glass-to-metal seal is used to insulate the positive ging efficiency to be too low, such as extremely low or high temperature.
5.What will happen if the batteries with different capacity are packed together?
If the batteries with different capacity or new and old batteries are used together, leakage, zero voltage and so on might happen. If the battery are rechargeable and are being charged, some batteries is overcharged and other batteries is not in full charged state. During the discharge, some batteries can not discharge fully and other batteries might over discharge. This way, the battery will be damaged.
6.How to activate a cell which has not been used for a long time?
A new cell is normally be adjusted at half-charge condition for reducing the risk during the transportation,but when storage for a long period, the cell need to be activated for better performance: Cut off the power of device then deeply discharge ( use your device ) , and then charge it until the full light on the charge is on, extra 1~3 hours charging is better.
