Thanks Alex, easy to follow
I need to remove the cable from the battery because my new battery did not have one. Do you know how to get this connector to let go? I didn't want to force it.
The cable for the battery seems to pull straight up from the battery to disconnect it, after which it can be attached to the new battery by just pressing it onto the battery.
I did not notice the absence of the connector on the new battery until after [I screwed all 8 battery screws in, scrolled up to reverse the battery removal instructions, realize I was not able to find the connector, and unscrewed all 8 battery screws again]. After that, I realized the old battery had a connector that I could use with the new battery.
This guide is less than ½ of a battery replacement guide; knowing how to remove the battery is quite helpful, but the guide, as is, is not foolproof.
Please, please improve this guide.
I plan [[to check the comments section of future part-replacement guides that I follow] and [to think much more carefully, fool that I am, before doing any actual replacement] whenever I notice the guide skipped everything after removal].
