It sounds like you're referring to a brand-new OEM (Original Equipment Manufacturer) battery for the HTC 10 Evo (also known as the HTC Bolt or M10f). The model number you've provided, B2PYB100, is the specific battery for this phone, with a capacity of 3200mAh and being in "0 cycle" condition, meaning it has never been used or charged before.

If you're looking to buy or sell this battery, it's important to ensure that it is compatible with the specific HTC 10 Evo model you have, as battery compatibility can sometimes vary even for phones with similar names. The battery should provide enough power for the device if it's a genuine replacement part. Make sure to properly dispose of or recycle old batteries if you're replacing one, as lithium-ion batteries (like the 3200mAh battery you mentioned) can be hazardous.

If you need any further details or help with installation, let me know!
