I will be happy to assist you. The battery on your model is a little tricky to access. I posted the factory instructions below. Just click on the image to enlarge it. You will see that you do not have to remove the handle to remove the battery.
I hope this is helpful. Please let me know if you need further assistance.
I can understand how this can be frustrating.I have attached a link from the Manage My Life website for the manual which shows where the battery is located,and also a link for the electric start. Hope this helps until an Expert responds. Have a great day !
