anyhow, i am sure the manual tells you that you only can use the original battery that came with the 8700, right?
just like I went to Walmart to get oil change, and asked them to change my light at the rear. they gave me some light bulbs with were from other model. They worked while the guy installed and showed me. However, once I drove off from Walmart, it stopped working. I finally found out the model of the light they gave to me were not comparable to my car. The guy who did the oil change just assumed they worked because they looked alike. ...
