Spare parts with excellent value for money Safe functionality and total compatibility with your notebook Perfect working for trouble-free installation in your CE & RoHs device - All relevant specifications for operational safety are respected Modern Li-Ion technology for optimal operation of your device Li-Ion rechargeable batteries (abbreviated in Li-Ion) are characterized by high energy, distinguishing itself to be among the most powerful. Compared to NiMH accumulators, for example, they have low self-charging and higher energy density. They are not subject to the memory effect and do not usually need any kind of maintenance, as they do not require them to be downloaded regularly. These batteries have a long life if kept properly and have a high number of possible charging cycles. Li-Ion batteries are generally used in high-energy portable devices such as smartphones, notebooks, cameras and electrical tools. Other areas of use are radio controlled modeling and photovoltaic. Caution: If the Li-Ion battery capacity is significantly higher than the original battery capacity (e.g. 1000 mAh and more), the spare battery could be heavier and thicker than the original battery. In some cases it could then lean slightly.
