Query: Battery is available, but not cheap

I've been using my Ryobi 155VP for nearly 10 years now. I have replaced the battery three times. I average three years per battery. The battery is available but will set you back at least $[...] each time. Ryobi doesn't appaer to support this anymore but parts can be found at BUYMTDONLINE.com. This is where the Ryobi site will send you. As of today, the 155VP 12 volt battery is $[...]. That's $[...] plus shipping. (They're heavy) Other than the battery, I had to replace the little plastic bump start piece a few times as well. I have a LOT of trimming so all in all it has held up well. Mine has never been used as a doorstop! :-)I love this trimmer. I have trouble starting the gas trimmers. I gave my old gas Ryobi away - after kicking it across the lawn a number of times!
