Windows 10: Mailing a notebook with lithium battery

What is the best way to mail a notebook with its lithium battery.
Sort of confused by latest postal requirements.
The pc has a 42wh battery. Can it be mailed with the battery intact. Does it get special handling?
The post office is much cheaper than using UPS or Fedex.
Any advice would be appreciated...thanks for your help!

I've got to agree with pa49, but chill out a little dude not everbody has your knowlege.

Here's some info from Wikipedia:

Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a longer time, they should be brought to a charge level of around 40%. Lithium-ion batteries should never be "deep-cycled" like Ni-Cd batteries.

Lithium-ion batteries should never be depleted to below their minimum voltage, 2.4v to 3.0v.

Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly.

According to one book, lithium-ion batteries should not be frozen (should not be stored below -40 °C), because most lithium-ion battery electrolytes freeze at approximately −40 °C (this is much colder than the lowest temperature reached by household freezers,
however).

Li-ion batteries should be bought only when needed, because the aging process begins as soon as the battery is manufactured.

When using a notebook computer running from fixed line power over extended periods, the battery should be removed and stored in a cool place so that it is not affected by the heat produced by the computer.

 

n95..battery life..

After 10seconds research I found this:

It is important to learn battery care information for Lithium-ion batteries to enhance the performance and extend the useful life of the battery. Because they are the newest technology batteries, they offer several advantages over NiMH and NiCd batteries. Lithium-ion
batteries are preferred for their lighter weight and higher performance. Lithium-ion batteries are typically 20-35% lighter and will provide 10-20% better performance than a NiMH battery of equivalent mAh rating. Lithium-ion batteries are also unique in that
they are not susceptible to the "memory effect".

A new Lithium-ion battery will benefit from an initial "conditioning" of the battery. For the first 3 charge cycles, fully charge the battery overnight and allow it to fully discharge before recharging. Once conditioned, Lithium-ion batteries will perform best
when charged at a rate somewhere between a conventional slow charge and a rapid charge. When rapid charging, Lithium-ion batteries require a charger designed to charge Lithium batteries. To achieve a true full charge when rapid charging, the battery needs
to be slow charged the last 10-15% of its charge cycle. Most "intelligent" desktop and Lithium-battery rapid chargers provide this capability. A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours).

So it appears that it is better to "condition" these batteries first off!!!

I ordered a LIPO battery from Adafruit in the US and they would not ship it by regular post. It had to go by currier. The reason stated was shipping restrictions prevented sending it by regular post. I'd call the post office before you box it up to see if they will even accept it. And if they will, how it has to be boxed up.
