We ordered 2 water fire extinguishers from [the] stores and they both came with the next due date on the M175-e tag blank. One bottle was last checked [last year] on the front of the tag and if we use the ECRA 0510-XXXXX the weight has to be checked yearly. So; this extinguisher would require [a] weigh in [a few] days. [The] extinguisher was taken to inspection and reweighed and [to see if] there [was] a way to change the shelf life of [the] M175-E tag [to be] filled out for [the] next due date in a year.To prevent this; on Form #45-XXXX; [the] Non-Rotable Parts Tag that came with the extinguisher and has a shelf life limit of [a few years] - which is the next hydro due date? Is [the correct] date to the next weigh date or next hydro due date - whichever is sooner? Or do we need to create a next service weigh date program for stores so when we get an extinguisher from [the] stores that comes with more than 75 days on the next weigh date as per the B737 #2 SVC Card B737-XX-XXXX? This should be in effect for both the water and Halon fire extinguishers.
Technician reported receiving two portable fire extinguishers from the stores without parts tags filled out correctly.
