I got used Braava 240 recently in excellent condition. When I want to put battery in wall charger it rapidly pulses amber then switches green. But when I put it inside Braava body and press Clean button it won't wake up.

What is the voltage in the battery? Try performing a load test.

Thanks for reply vic. I've purchased new battery and it works fine both robot, wall charger and battery. So this was fault on the side of old genuine battery that comes with this used machine to me. Now, any idea how to check its manufacture date (battery, robot) ?

I have a few Braavas' and I have a problem with the battery it seems like the contacts don't line up when I plug in the battery. Something is wearing out over extended use.

If I plug in the battery while holding down the power button I can usually wiggle it in and out until works. I can see where the robot turns on and position the battery so it works. It just takes time.

Sometimes I can add tape to space the battery so they line up.

The contacts are pretty delicate I have tried scraping them and that sometimes work but more often that not it damages the batteries

I have at over 10 batteries and this seems to happens to the older batteries I have checked lipo voltage and the batteries are well withing acceptable voltage. Its an issue with the contacts.

Anyone else having issues or have solutions I have at least 4 dead batteries and its not the battery it the connector.

I am contemplating opening up a robot and wiring an 18650 battery holder outside the robot.

Anyone have other solutions.
