Never used battery for a Palm Treo. This was included with the phone when I bought the whole setup. I've since moved on to other smartphones, and found this battery in my desk drawer. This battery has never seen the inside of the phone.

Here is a link to Amazon where you can buy the same unit for $4.20 + shipping. This link also has a picture of the exact same battery.

I will send it by USPS priority mail, which should cost $4.95, plus I'd like at least $1 for my time in packing and delivering to the post office. So contact me with $5.95 and I'll get it shipped to you.
