I've seen videos of some people taking off the caps on their batteries and just dumping it in to top it off and other people just putting a small amount in the bottom. How do you know how much to put in the battery for it to be considered properly filled. I know there's a ton of YouTube videos but trying to see what the majority are doing vs 1 person who may or may not on YouTube. If you have a link to a video of the proper way I'd be interested in seeing that too.
Thanks
