Which Tool Battery (counterfeit Vs Genuine) Brand Wins?

transcript reads "64 G," almost certainly a dropped digit for 604 g, since the narrator separately states the counterfeit is "43 g less" than the genuine 647 g battery (647 minus 43 equals 604); kept flagged rather than silently corrected

the transcript gives two different figures for this battery: 724 g while still weighed inside its retail packaging, and 670 g in a later, separate weighing; both are kept as reported rather than reconciled, since the transcript does not explain the discrepancy

the transcript gives two different figures: 646 g while still weighed inside its retail packaging, and 600 g in a later, separate weighing; both kept as reported

(attempts were 11.51, 9.55, 8.3), almost 2 seconds faster than the counterfeit's fastest attempt

(attempts were 10.01, 11.3, 11.41), progressively slower with each attempt

(attempts were 6.49, 5.36, 5.72)

(attempts were 6.65, 7.27, 6.96), did not speed up with warmup like the genuine battery did

(attempts were 11.87, 9.81, 8.57), almost 1.5 seconds faster than the counterfeit's fastest attempt

(attempts were 10.42, 10.79, 11.05), progressively slower with each attempt

started at 20.6 V, ended at a 13.8 V safety cutoff at 41 minutes, delivering a figure the transcript renders as "84.78%7" Wh (almost certainly 84.7 Wh with a stray caption artifact, kept as literal with a flag)

started at 20.5 V, ended at just over 31.5 minutes, delivering 65.3 Wh against an advertised 100 Wh

held around 19.8 V early and 18.3 V at 15 minutes, lasted about 42 minutes, delivering 86.63 Wh, about 30 Wh more than the counterfeit

dropped to 18.6 V within 2 minutes, 17.5 V at 15 minutes, test over at about 29 minutes, delivering only 56.5 Wh

held around 19.4 V at 1 minute and 18.9 V at 5 minutes, lasted about 44 minutes, delivering 88.5 Wh

dropped to 16.7 V within 1 minute and 16.1 V by 5 minutes, test over at only 7.5 minutes, by far the shortest runtime of any of the 6 batteries in this video

has a circuit board/interconnect that acted as a fuse during the short circuit test, confirmed genuine Samsung 25R cells

battery case appeared melted and was difficult to open; had an interconnect that acted as a fuse during the short circuit test; cells confirmed not to be genuine Samsung 25R cells; an earlier visual inspection separately noted "no circuit board," which is not fully reconciled with the interconnect/fuse found during disassembly, kept as reported

has a visible control board with green-colored cells (versus blue on the counterfeit), fully encapsulated in plastic molding; one disassembled sample, described in the transcript as "the genuine Milwaukee," is stated to definitely not contain genuine Samsung cells and would not charge afterward, attributed to a failed control board; this is a surprising and internally inconsistent finding for a battery labeled genuine, and is flagged rather than resolved

has a control board and an interconnect that acted as a fuse during the short circuit test, but no visible spec information printed on it; instructions included in the box were for a 4 volt and 12 volt Milwaukee battery rather than the correct 18 volt instructions; serial number printing was noticeably harder to read than the genuine battery's silver lettering

control board present, cells encased in plastic, country/spec information not detailed in the transcript for this specific unit

no obvious external signs of failure were found when the units were opened; none of the narrator's several Makita chargers would charge these batteries; cells confirmed not to be genuine Samsung cells

before powering down, maintained noticeably higher RPM than the counterfeit, battery life indicator still showed 2 bars afterward

lasted close to 3 minutes before powering down, battery very hot, battery life indicator down to 1 bar

before shutting down, maintained higher RPM than the counterfeit throughout; battery very hot afterward with a flashing low-battery indicator, not fully dead

before shutting down, unable to maintain RPM throughout the run; battery very hot afterward with no signs of life

better than the counterfeit's 128 in lb

21 in lb better than the counterfeit's 123 in lb, matching the stated difference exactly

the counterfeit 18650 cells are explicitly stated as not designed to safely discharge like the genuine Samsung cells
