My nokia 6.1 plus battery has these labels on it's flex. The phone has been off for about a year and doesn't get ON so I want to shock it's battery. The problem is I do not know battery terminals and the polarities. What are the terminals?

    \$\begingroup\$ "Shocking" a lithium battery sounds like an incredibly bad idea. If the battery is dead and won't take a charge, replace it. \$\endgroup\$ Commented Dec 24, 2021 at 20:27

  • \$\begingroup\$ @ElliotAlderson Well, at the time, battery was in a very good condition. I read elsewhere if we put about 7.5V on the terminals, it may help it get back. Also there is this board on the market that repair shops use to bring dead battere's back to the life. I will try once in a safe garage :) shopee.com.my/… \$\endgroup\$

    \$\begingroup\$ @Behzad Although the procedure might bring a dead battery back to life, note that it will certainly not be in a "very good" condition. More like "barely working". A battery that got drained so much that the phone refuses to charge it is permanently damaged and at a small fraction of the original capacity. Better replace it if you want to use the phone. \$\endgroup\$
