I’m trying to change my battery on my BA II plus pro and I’m struggling to get it out. I’ve tried to push it down, use a pen to move it a bit to the side but the old battery won’t budge.
You have to lift the battery up, not down, nor to the side. Up UP! There’s even an instructional diagram under the battery cover on the case. If this is a serious post, then perhaps you’ll need to get that hacksaw and use it for its intended purpose.
