It's important to handle old batteries properly according to their types, because some batteries could cause a risk to safety and environment if mismanaged. A battery's label or packaging helps to identify the battery type. Then, to determine which batteries are acceptable for landfill and which batteries need to be recycled or sent to a hazardous waste facility.

For managing old single-use batteries, they come in many sizes like AA, AAA, 9V, C or D cell, which can be found in TV remotes, toys, game controllers, flashlights. They are safe enough to be trashed, but it's best not to do so. It's better to recycle batteries anyway, turning them into a secondary commodity and have a productive life beyond powering.

As for old rechargeable batteries, such as rechargeable 18650 Li-ion batteries, they should never be thrown in the trash can, because these type of batteries contain heavy metals that can be hazardous to the environment. And they should be recycled in your local facility that will accept these batteries.

And there are some necessary preparations for old batteries recycling. To avoid a fire hazard, pls tape each end of the battery with clear, non-conductive tape to prevent residual discharge. Or you can place each battery in its own plastic bag instead. Please place the wrapped batteries in a cardboard box or plastic container. Don't place them in a metal box because they could spark causing a fire. Then, you can drop them off at the nearest special recycling facility safely.
