How to replace the EMO battery

I see a growing number of inquiries about EMO charging and power issues here recently.

Lithium polymer batteries mounted on EMO are more efficient than mercury, manganese, and alkali batteries, but eventually, charging efficiency will decrease over time.

Can EMO’s battery be replaced by an average user with basic soldering technology? I want to know what kind of battery model I should use if I replace it.

I want to let Korean users of the online community I run know this tip.

Although EMO’s battery was designed to be non-user replaceable, just like most electronic devices there is always a way. But it would render any warranty or return null and void.

EMO’s battery is a simple square LiPo soft pack, and it is glued to the inside of EMO. It would need careful and proper removal technique but it would be doable by someone who is proficient in electrical work. The actual battery replacement could be sourced online once the part number is known.

I do not endorse anyone doing this themselves as there are safety issues that could lead to personal injury or loss of property through fire.


If EMO is working fine then the battery life is his main limitation. I have schools and skills to replace it by myself, we just need the part number of the battery and a possibility to buy it.

If EMO’s battery does eventually fail out of the warranty period, then the replacement needs to be;

Part Number: 603450, 3.7v, 1200Mah, 4.44Wh Li-polymer battery
