The 53TBATDOORBK-5 is a package of five black replacement battery doors for the 1553T size of the Hammond 1553T hand-held "T" soft side enclosure family. It is listed in the series "Replacement Panels & Battery Doors" table for the 1553T enclosure size, making it the part to order when a battery door on a 1553T battery enclosure is lost, damaged or needs to be kept as a service spare.

Each door is molded from ABS plastic in black. The part page gives a size of 2.62 in x 2.17 in x 0.11 in (67 mm x 55 mm x 3 mm), and the 5-pack ships in a bag with a shipping weight of 0.05 lbs (0.02 kg). The doors are RoHS and REACH compliant.

In the 1553T series, battery door and compartment versions carry part numbers ending in "BAT"; the 1553T battery enclosures in this color are 1553TBKBAT. On those enclosures the compartment includes 8x battery clips (for 4x AA batteries) and 2x 9 volt (PP3) battery clips. The series spec sheet notes that battery versions include a long-life three point battery door.

For a grey finish, the matching 1553T battery door 5-pack is 53TBATDOORGY-5. Replacement end panels for the same enclosure size are sold in 10-packs as 1553TPLBK-10 (black) and 1553TPLGY-10 (gray). The series cautions that some chemicals can damage or weaken plastic, so check cleaners and fluids against the chemical resistance statement.
