    Instead of banging on it with a scraper and hammer, try cutting through the stickers on both sides with an exacto or similar blade. Then you can hold the battery in a vise and just push it open with no problem. I did a video on this. The ones I have opened have contained mostly LG cells and they are the most difficult to get the cells out due to the amount of adhesive they use. The Sony and Molicells were the easiest to get the cells out.

    Edit: I got a response from a person later the same day, and it looks like they will be helping. Seems like I got a bad batch. So far so good!

    I use these backs, that glue is so messy to get off. I used an exacto knife to cut around the glue. I might need to re-wrap 1 battery out of each set. Not sure I recommend this back. I brought 20 of them. I would recommend the 3 battery modem one when it's back in stock.

    Very easy method to open these type of cases, including laptop batteries with no tools. Use a "q-tip" and spread a spearing coat of gasoline between the 2 halves of the clamshell. Wait 2-3 min the case will almost fall apart in two sections. Chemicals in the gasoline dissolve the adhesive. I was shocked how well this works. Lots of videos on this online. give it a try.
