Three Electric Contacts vs Four on the EGO Blower.

I have a question regarding the EGO Blower.  Back on the mounting slot for the battery, I've seen some EGO blowers with four electric contacts (the metallic plates which insert into the EGO battery contacts) built into the blower, and some EGO blowers with only three electric contacts instead. 

Thus, on the EGO Blowers with only three electric contacts there is nothing being inserted into the slot marked "T" (next to the negative terminal slot) on the EGO Battery.  And yet the blower appears to function normally regardless.

Are both arrangements normal?  I'm not technically savvy enough to understand the difference between these two setups, so I was wondering if anyone could offer an explanation.  Mostly I'm wondering if the blowers with only three electric contacts is a production defect.

Hi Joe, this is normal and not a production defect.  Some of the early generations of blowers were made with 3 contacts while later generations were made with 4.  There is absolutely nothing to worry about.  Keep in mind that we stand behind our products and if you happen to have an issue, our 5 year (3 year on battery & charger) warranty will be there to help you!
