Features:
1. High Capacity 9V Size Lithium rechargeable battery.
2. Provides long use time, and widely used in many equipments.
3. Excellent replacement for standard 9V size battery in all the devices.
4. Convenient operation without memory effect. Can be charged anytime.
5. Can be rapidly charged with any quick charger, smart chargers, plug in charger or universal chargers.
6. Can be recharged for up to 500 times, providing big saving by replacing hundreds of throw away 9V batteries.
Product performance:
1. The unity of monomer is good. A series of international standard specifications and models have been established for cylindrical lithium batteries. The processing technology is relatively mature and perfect, which is suitable for mass production and uninterrupted production.
2. Greater than the energy. At present, the actual specific energy of hyb steel shell battery is 100-135w.h/kg & 280-353w.h/l (2 times of Ni Cd and 1.5 times of Ni MH). With the development of technology, the specific energy can be as high as 150w.h/kg and 400 & w.h/l.
3. Long service life. The service life of lithium battery is very long. The cycle life of lithium battery can reach more than 500 times in normal use, which is more than twice that of ordinary battery.
4. Safety and environmental protection. Lithium batteries do not contain elements such as cadmium, lead and mercury, which pollute the environment.
5. There was no memory effect. One of the disadvantages of some Ni Cd batteries is "memory effect, which seriously restricts the use of batteries, but lithium batteries do not have this problem.
6. Large capacity. For example, the capacity of 18650 lithium battery is generally between 1200mAh and 3600mAh, while the capacity of general battery is only about 800mAh.
Performance Curves of Lithium Cell:
1.Lithium Cell Charge Curve (Charge at 1C)
2. Lithium Cell Discharge Curve (Discharge at 1C )
3. Lithium Cell Cycle Life Curve
How to Extend the Life of Lithium Batteries?
1.. Lithium battery use environment and maintenance methods:
(1) The temperature should be suitable, the charging temperature of the lithium battery is 0℃～45℃, and the discharge temperature of the lithium battery is -20℃～60℃;
(2) It should be in a clean, dry and ventilated environment, avoid contact with corrosive substances, and stay away from fire and heat sources;
(3) Lithium battery packs have no memory effect and can be charged as they are used, but it should be noted that lithium batteries cannot be over-discharged. Over-discharge will cause a very large capacity loss;
(4) Do not mix the battery with metal objects, so as to prevent the metal objects from touching the positive and negative electrodes of the battery, causing a short circuit, damaging the battery or even causing danger;
(5) Avoid frequent overcharging. Overcharging will cause the internal temperature of the battery to rise to a high level, which is harmful to the lithium-ion battery and charger. Therefore, a full charge is enough to turn your lithium battery into a small bomb.
Summary: The battery is a consumable product, and its life span is fixed (the number of charging and discharging is usually 300-500 times), so mastering the correct method of use is the secret of battery life extension.
