Today's laptop batteries are all lithium batteries. For lithium batteries, charging them for a long time after using them has no effect at all, and it is even harmful. Because lithium batteries do not have the so-called "cache effect", only the early nickel batteries have this feature. Therefore, we should try to avoid the situation that the battery power is exhausted and recharged, because it will put a lot of pressure on the battery and cause damage. It is more practicable to charge when the remaining power is about 20~30%.

Room temperature (20 ° C ~ 30 ° C) is the most suitable operating temperature of the battery, too high or too low operating environment will reduce battery life.

When using the notebook in an environment that provides a stable power supply, removing the battery to extend battery life is not correct. Because the charging circuit in the battery is automatically turned off when the battery is fully charged, there is no overcharging.

Machining Brass

Brass has excellent CNC Machining Turning performance, high-speed machining turning under the brass can get excellent surface finish. Our technical team has very good experience in machining brass, machining brass including brass plate, brass rod, brass tube. Brass hardware parts has high strength, good plasticity in hot state, good plasticity in cold state, good machinability, easy welding and good corrosion resistance. Brass parts are very durable. It is electrically conductive and does not usually corrode or deteriorate over time. Thus brass is often used to produce products with longer service life. Machining brass parts Widely used: pipes, radiators, ship parts.
