Hi,
I have a Logitech Harmony one universal remote controller. I had removed the battery prior to storing it a few months ago and am unable to find it. Can anyone suggest where can I buy a replacement battery for Harmony one in India?

Thank you for this creative suggestion @shankarcams. Logitech is not responding to my mails. I will try what you suggest with some hope.
