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\$ LiPo and Li-Ion don't always mean the same thing when used by different manufacturers. Check the charging info for the cells. My charger does LiPos to 4.2v, but Li-Ions to 4.1v. Just sayin'. \$\endgroup\$ – Neil_UK Jun 13 '18 at 9:33

Here is a really great guide to the differences between LiPo and Li-ion battery chemistry. They are very similar but have important differences. You must always be careful when charging and discharging lithium batteries, because they can explode if done incorrectly.

The short answer is yes, you can do that because the voltage is the same and the capacity is larger. This means that the charger voltage will be correct and that the charging current will be lower than 1C, which is safe.

The downside is that it will take a long time to charge in comparison.

  • \$\begingroup\$ What are the differences between Li-ion and LiPo?? (Except for the phase (liquid vs solid) of the electrolyte.) \$\endgroup\$ – Oskar Skog Jun 13 '18 at 8:05
  • \$\begingroup\$ That's just it, the electrolyte. LiPo is actually Li-ion Polymer. The electrolyte means the cell can be made smaller, lighter and has a slightly higher energy density. \$\endgroup\$ – MIL-SPEC Jun 13 '18 at 8:08
  • \$\begingroup\$ What are the important differences then? \$\endgroup\$ – Oskar Skog Jun 13 '18 at 8:23
  • \$\begingroup\$ Why will it take long time to charge? As far as I know li ion and li polymer require the same voltage to charge \$\endgroup\$ – Abu Bakar Jun 13 '18 at 13:16
