FS: T410s battery free for mailing cost

[RRHODY]

I have a battery labeled "T410s" and no longer have that laptop. I have absolutely no idea of the condition, or even if it really is for the T410s . Non-Lenovo "Replace 42T4688"
If it can be mailed in a flat rate USPS envelope, I'd send it to who ever want it for the cost of mailing.
