Sony's PlayStation is the successor lithium facts to the PlayStation the world's most popular and as recently as July the world's best selling video game console.
To avoid this you can check date of manufacture and buy one that is more recently out the gates of the factory. As a workaround you can buy any netbook while it's under warranty test the battery and if it's not up lithium facts to your expectations you can send it back as dead on arrival and demand for a replace.
Even the best solution has internal resistance, which it discharges through over time, thus that optimal 40% capacity drips away. Another thing Lithium-Ion cells absolutely loathe apart from heat and being overcharged is being fully discharged.
For this cordless drill comparison I decided that the chemical properties weren't important to me. What mattered was why an Li-ion battery may be better than a nicad battery. My drill comparison came up with 2 major reasons. Li-ion batteries weight is about half that of a nicad battery. In other words when you hold a 18 volt lithium bettery stock ion powered cordless drill driver over your head you will notice a major difference in the weight over that of a 18 volt nicad drill driver.
The longevity of the cheap cell phone batteries you have also depend on the model of the mobile phones. The appearance of the discounted cell phone battery for cellular phones also depends on the model and make of the wireless phone that you are using.
The bottom line, be gentle to your lithium-ion batteries. If you excessively charge the battery, with high voltages, and heavy load conditions, it will shorten your battery's life. It's best to charge at a slower rate.
