Bosch Intuvia: replacing internal battery

In this video I'm replacing the internal battery of a Bosch Intuvia (used on Bosch ebiks: classic, active line and performance line).
When the Intuvia has a dead battery, you can only power up the bike with the button on the battery. Luckily this is fixable without buying a new one.

wow even applying silicone for the gasket impressive.. .. i was typing this comment and there was you text haha .. nice attention for detail btw. the moment i saw the gasket i thought after this diy fix i would buy the intuvia screen / rain protector just to make sure..

Many thanks Wim this was VERY helpful but sadly my 50 YR old eyes wont be able to solder something that small but hey my teenage daughter will have to do it.

very good tutorial, i also have to change the battery of my bosch intuvia ... where did you buy the new battery? on which website? thanks :-)

[@wim4245]

The battery type is 052030 (3,7 V, 250 mAh). I did not find a reputable seller in Europe yet. Till now, I order from aliexpress:

My intuvia seemed to have the same difficulty. After opening the display and testing the old battery this one showed still 4,1V.
Should I replace it anyway ?

[@wim4245]

I would assume that your battery is still fine

[@harbuzadrian7257]

good evening can you tell me if after you changed the battery, the general mileage was reset ?, or was it memorized? thanks

[@wim4245]

That's all stored in the drive unit.

[@fenecca]

Thanks a lot! On the back of my display, it says 5.0V === 500mA. Would the 502030 3.7V 250mAh be fine?

[@wim4245]

Those are the specifications of the USB port. The battery is fine.

[@kentyboy1951]

Did you try charging it up off the bike?

[@wim4245]

Won't work when the battery is dead. When it's just discharged, you can indeed charge with the USB connector

[@neil16377]

Hi, could the USB port be replaced?

[@wim4245]

I don't have a source for them. When the port is broken, I just use another display to update or diagnose the bike.

You don't need instructions to change the 3,7V LiPo battery. Everything you need i the capacity and dimensions of the LiPo. On the video you can see the labeling of the battery very badly.
