This item was included when I purchased several used units, which were almost new. I haven't used it at all. I confirmed its operation with an ip100. However, since it's a battery, the degree of wear is unknown. I was able to print several color pages normally, but the battery load varies greatly depending on what is printed, and I haven't tested it to its limit, so please prioritize the current condition. I haven't fully charged the battery either. There is no sign of use, and the exterior is very clean.
