Samsung 13Q and Sanyo UR18650Y date codes

Salvaged from a WORKX WA3512.1 battery and a Toshiba PA3535U-1BRS battery, respectively. Labels are as follows:

INR18650-13Q

SAMSUNG SDI

088 3

SANYO L

UR18650Y M48C

I'm pretty sure the 13Qs are fake. The dot matrix font doesn't match the font on my known legit 30Qs.

Never mind on the Sanyos. I tried charging them at 1A and they got extremely hot. They’re going back to the recycling bin.

See HKJ's review of the 13Q and compare the font. HKJ's sample also says O88 or Zero88 but the last digit is a 2. The batterybro date check tool doesn't handle that code. The datasheet is from 2007, 11 years is enough for date codes to change.
