Hi, I'm not sure how to reach you. I was going to buy some batteries from your Amazon store & I've made sure it is correct model series and number for older model & even though it's correct, it also says it has to have screw in bottom. Mine does not, so which battery do I need for HX6220-05? Double batteries AAA? Please help if you can, ready to order & pay. PS ... I've watched your videos for a little while, thank you so much for your attention to detail! I was happy to see the name "Million Magnets" when I was trying to purchase batteries! V.
