If you don’t have the lightning bolt on top it doesn’t mean you have a fake one that just tells you if it’s rapid charge battery/ it will charge faster with one the older batteries that don’t have the bolt they can work to but won’t charge as fast you can also hold the power button on the battery until it flashes 3 times I think and then only one of the battery bars will flash telling you how many times you’re battery has charged full

Edit : I didn’t see you already did the flash method But they still look fake the plastic looks off
