Bests & Worsts Reviews from Amazon

I've had this printer for about a year and a half and found it useful. I liked that it was USB powered, took up little desk space and had easy to use Windows software. Today I attempted to print and found that the internal Li-ion battery had failed. The battery will no longer hold a charge and this prevents the printer from working. Why in the world is this a battery powered device in the first place? There is no user interface on it. The only time it is useful is when it is plugged into a USB power which is, presumably, attached to a laptop/desktop which is providing it power. The battery part number is w003688 and is available for sale at dymo.com for $26 + shipping. This is the same price I originally paid for the entire printer. I don't mind so much paying inflated pricing for the printing tape but to be also dinged $40 for a battery every year or two ain't cool. ---------- Edit: I won't be beaten! Per other comments I am using a 9V alkaline battery to trick device into working. Decided to solder a battery connector to the Li-Ion battery pack terminals. See images. Seems to work perfectly. I will probably disconnect USB port from computer when not actively using this as I am not sure that constantly applying the Li-Ion charging voltage/current to the alkaline battery is not a fire hazard.
