wamart battery jump pack today, approved

bought walmart jump pack one yr ago.
on sale, i paid 15$ or less.
used but never hard tested....till today.

woke up to -5 f and stone cold dead battery.
jump pack not charged or used in six mos.

connected and charged for maybe two mins.
turned over slow but started first try...
im sure if i wouldda let charge 10mins,
it wouldda bump fired..
