I posted this reply in the other thread you started about this:
The first generation of ego-t
batteries didn't have the 5 click feature, and some stores are still selling them. The 900mah
batteries don't have it, the regular ego batteries don't have it, and the battery on the usb PT doesn't have it (even the 1000mah PT battery doesn't). You can purchase a battery button protector ring if your battery doesn't have it. Your best bet is to ask the vendor before buying if the website doesn't specify that the battery has the 5 click feature.
