Leak-proof packaging for wet batteries

A method for packaging at least one battery containing corrosive liquid, the method comprising:

• providing a substantially rectangular box forming an inner container configured to accept the at least one battery therewithin and having an inner-container surrounding wall that includes a bottomwall, a topwall and a sidewall between the bottomwall and the topwall, the topwall forming an inner-container closure of an inner-container access opening, the inner container being substantially free of pointed corners;
• enveloping the inner container with a plastic bag forming a fluid-impermeable intermediate container having a top end forming a fluid-impermeable lock;
• putting the intermediate container into an outer container formed by an outer-container surrounding wall including an outer-container topwall forming an outer-container closure of an outer-container access opening;
• loading the at least one battery into the inner container;
• closing the access opening of the inner container with the at least one battery therewithin;
• sealing the fluid-impermeable lock of the intermediate container with the inner container therewithin;
• and
• locking the access opening of the outer container,
• whereby the defective battery containing corrosive liquid is protectively packaged for leak-free transportation.

In combination a defective battery and package therefor, the combination comprising:

• the defective battery unreliably containing corrosive liquid;
• and
• a leak-proof package containing the defective battery, the package comprising:
• a substantially rectangular box forming an inner container configured to accept the defective battery therewithin and having an inner-container surrounding wall that includes a bottomwall, a topwall and a sidewall between the bottomwall and the topwall, the topwall forming an inner-container closure of an inner-container access opening, the inner container being substantially free of pointed corners;
• a corrosive-fluid-impermeable intermediate container sealing the inner container therewithin, the intermediate container having a top end forming a fluid-impermeable lock;
• and
• an outer container enclosing the intermediate container and having an outer- container surrounding wall that includes an outer-container topwall forming an outer-container closure of an outer-container access opening,
• whereby the defective battery unreliably containing corrosive liquid is protectively packaged for leak-free transportation.

In combination a wet battery and package therefor, the combination comprising:

• the wet battery unreliably containing corrosive liquid;
• a leak-proof package containing the defective battery, the package comprising:
• a substantially rectangular box forming an inner container configured to accept the defective battery therewithin and having an inner-container surrounding wall that includes a bottomwall, a topwall and a sidewall between the bottomwall and the topwall, the topwall forming an inner-container closure of an inner-container access opening, the inner container being substantially free of pointed corners;
• a corrosive-fluid-impermeable intermediate container sealing the inner container therewithin, the intermediate container having a top end forming a fluid-impermeable lock;
• and
• an outer container enclosing the intermediate container and having an outer-container surrounding wall that includes an outer-container topwall forming an outer-container closure of an outer-container access opening,
• whereby the defective battery unreliably containing corrosive liquid is protectively packaged for leak-free transportation.
