Is it possible to replace a battery for headphones? I would like to replace a 052030 li po battery with a Nokia BL-5C Lithium Ion battery. The li po battery is rated at 130 mAh with 3.7v. The Lithium Ion battery, on the other hand, is 1 Ah with 3.7v.

Thank you for your help.

  • \$\begingroup\$ Terrible punctuation! Sentences start with capital letter. Space follows question mark. Basic stuff! To run the gadget with a different battery chemistry with the same voltage should be fine. Charging it however, will probably prove difficult. Do you possess the skills needed to characterize the existing charging and/or replace it? \$\endgroup\$ – winny Jun 12 '18 at 20:39

    \$\begingroup\$ Possible? Yes. Advisable? No. Li-Ion batteries need to be charged in a different way (much more careful) than NiMh batteries. Li-Ion batteries need a special charging circuit designed for Li-Ion cells. If you break that rule then you will probably damage the Li-Ion battery. winny already mentioned it, next time pay more attention to punctuation and correctness. Your question is very messy :-( \$\endgroup\$ – Bimpelrekkie Jun 12 '18 at 20:56

    \$\begingroup\$ Please edit your orginal question. It still says NiMH. \$\endgroup\$ – winny Jun 13 '18 at 8:25

Many links in Google say that a 052030 battery is a Li-PO, not a Ni-MH type. A li-Po is almost the same as a Lithium-Ion type but the huge battery will take a very long time to charge.
