The bill wants to make sure that the Department of Homeland Security doesn't buy certain batteries from some countries, especially China, to keep everyone safe, starting in 2028 and lasting until 2033. If there are no other good options, they can ask for a special pass to still buy those batteries.

The "Decoupling from Foreign Adversarial Battery Dependence Act" is a plan to stop a big part of the government, called Homeland Security, from buying batteries from certain foreign companies, mainly from China, because it might not be safe. They will start doing this in 2027, but if it's really hard to find different batteries or they don't cause any problem, they can sometimes still use them.

H. R. 8631 says that after 2027, the U.S. government can't buy certain batteries made by companies in places like China if they might be unsafe, but exceptions can be made if they aren't risky and there's no better choice.

The bill says that starting in a few years, the people in charge of keeping the country safe won’t be allowed to buy batteries from certain countries, like China, unless there’s no other choice, to make sure there's no risk and everything is safe.

The bill wants to stop the Department of Homeland Security from buying batteries from some companies in China after 2027, but the head of the department can make exceptions if it's safe or for learning new things. They also have to tell Congress how this rule might change things 180 days after it starts.
