Chainsaw Repair

I have not been able to get the reps to answer a few more technical questions on the ECHO line.  But did find some answers deep in the Q&A on the HD website for some of these products.  I would feel a lot more confident if I could get a direct answer from an ECHO cordless, or Home Depot rep.

- It "sounds" like the batteries are covered under the five year warranty, for residential use only. Not sure how you would prove or document this. HD may actually be more casual about this, than an ECHO dealer.

- ECHO clearly states that you cannot charge their batteries using a 12 V inverter in your vehicle. Oregon says that you can charge their batteries as long as it is the right kind of inverter (pure sine wave?).

- Still unclear which accessories can be used with their string trimmer powerhead. Apparently, some ECHO attachments will fit, but may not have adequate power. For example, I can't get an answer about using a pole saw attachment.
