may be overheating since soft surface cannot dissipate heat. Thefore, avoid doing so is important.

Let's talk about storage. In general it is not a good idea to leave your Toshiba laptop in your car. Extreme heat in the day and then cold in the night and cycling this over and over will not be good for your laptop. Hot batteries will discharge very quickly and this ruins the battery.Toshiba PA3399u-1brs battery Toshiba PA3399U-2BAS Battery TOSHIBA PA3399U-2BRS battery TOSHIBA PA3450U-1BRS battery

Charging a battery is a must for continued performance of laptop mobility. You don't need to totally discharge, then recharge the Toshiba laptop battery occasionally to make it last longer. Discharging and charging does not increase the life of a Lithium Ion technology battery. Also, the Toshiba battery is designed to stop using the charger when it reaches full charge therefore there is no worry about the "overcharging" problem.

The next important piece of equipment you need is the ac adapter. Without it, you wouldn't be able to use your computer after an hour or two. You can extend the life of the Toshiba adapter by treating it gently, never pulling the cord to remove the plug from the wall and never pinching the cord in drawers, under furniture legs or in doors.

If you're like me, your laptop spends as much time on your desk as it does on the road. If you are leaving the battery connected while on AC power in office, it's in the loss of charge cycles. Battery's temperature is higher on AC power resulting in accelerated aging. That's not good for battery's life. Thefore, just use the battery when you need it. When on traveling, try to rely only fitfully on your batteries. The optimal charge level is 40% for prolonged storage. For Lithium-Ion Toshiba laptop battery cells, full discharge/recharge cycles result in an increased loss of capacity, so, partial charge is better for keeping the battery life. If you run your laptop remotely all the time causing deep battery drains, you won't get as much life out of your batteries.Toshiba PA3384U-1BRS Battery TOSHIBA PA3399U-1BAS battery

"There are currently no approved and tested containers that can sufficiently contain the known effects of accidental lithium metal battery ignition," the safety directive said. "Common metal shipping containers, pails and drums are not designed to withstand a lithium metal cell fire."

The halon fire suppression systems used in the lower cargo compartments of passenger and cargo planes aren't able to put out fires caused by lithium metal batteries. However, the systems can extinguish fires caused by lithium ion batteries, which are rechargeable batteries similar to the kind used in many cell phones and laptop computers.

Lithium ion batteries are also flammable and capable of self-igniting. They can generate temperatures very close to the melting point of aluminum, which is what the exterior of airplanes are typically made of, the safety directive said.

John Cox, an aviation safety consultant and former airline pilot, said the safety directive indicates it is even easier for lithium battery fires to spread than was previously known.

The Pipeline and Hazardous Materials Safety Administration proposed new regulations in January that would require lithium batteries be treated as hazardous cargo. Battery shipments would have to have special packaging and workers who ship them would have to receive special training. There would also have to be special labeling and pilots would have to be told that their cargo contained lithium batteries.Toshiba Pa3356u-1brs battery Toshiba PA3383U-1BRS Battery

The regulations, which have not yet been made final, have been strongly opposed by the electronics industry, battery makers and some cargo carriers, including UPS. Industry officials have estimated the cost of the proposed regulations at over $1 billion a year.
