Product Description: Includes Rechargeable Battery - Battery Housing - Battery Charger to take your Canon printer on the road
Rating : - It is a battery and it works. Simple to install.Snap the battery into the holder and then screw it onto the back of the printer using a coin. Then charge up the battery. Don't freak out when you see the three green lights flashing -- that just means it is charging. They go off when charging is complete. The battery seems to hold a charge for a long time. People seem surprised to see the printer suddenly start printing when it is just sitting on the table with no wires. It is rather expensive in my opinion, but it does the job.
