Braava 380t Spare Battery - How to charge?

Postby tks » April 14th, 2017, 4:20 am

Bought the iRobot Braava 380t. Would say I am 80% satisfied. On the other hand, I am 98% satisfied with my Xiaomi Mi Robot Vacuum Cleaner. My short video on the Braava 380t:

My main complaint is that the battery runs out fast and I have to recharge for a few hours before I can use it again. Hence, I am not able to complete mopping my entire house in one afternoon. I found that I can buy spare batteries for about $15 from Amazon and taobao. ... ZV7YJPNP74

Seems easy enough to replace the battery: ... es-battery.

But I do not want to have to charge the battery in the Braava. Can I buy or fabricate an external charger so that I can be using the Braava and charging the spare? And when the Braava runs out of battery, I will swap the batteries, one to use and the other to charge?

You will probably need to make an adapter for the plug but any RC charger for NIMH/NICAD batteries will work.

Putting wire/pins into the red and black locations and hooking up with alligator clips would work.
