iRobot Roomba 4220 battery charger

Hi!

I require your help regarding a problem I’m encountering.

Hi,
I have an iRobot Roomba 4220. The battery won’t charge. I got a new battery and the Roomba worked fine until the battery died.Then I also got a new charger cord. Still won’t charge. After some research, it looks like I might have to buy and install a new mother board .
As an alternative, could I buy a charging device that I can just independently recharge the battery outside of the iRobot, and then just reinstall it each time to run it?
And where can I get one of those?
Thanks for any help on this issue.

Thank you so much in advance for your help!

Hi @Opheliavirginia and welcome to our forum!

Can you send the link where you bought this new battery?

What is the type of the battery and what are the voltage/current/power specification for it?

Thank you.
