Batboard

Effective May 16, 2012, the Postal Service™ will revise Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) section 601.10.20 to codify that primary lithium metal or lithium alloy (nonrechargeable) cells and batteries or secondary lithium-ion cells and bat­teries (rechargeable) are prohibited when mailed interna­tionally or to and from an APO, FPO, or DPO location. However, this prohibition does not apply to lithium batter­ies authorized under DMM 601.10.20 when mailed within the United States or its territories.
