I think the specific battery model number is printed on the box. The fuel gauge batteries end in “T”.

Thank you. I think we are on to something here.
My wife just picked up the trimmer this morning and told me the battery model on the box ends with an X. Guess I'll have to return it and look for one with the T at the end.
Thanks,

Still not sure if this is correct or not. Just seen plenty of fuel gauge batteries on eBay that actually have the X at the end of the serial number. This might be a losing battle.

Open the box and solve the mystery

Opened the box and the battery has a June 2019 date and is not the fuel gauge battery.

Issue is not sure if there are any currently available with the new battery.  Current stock may all have the original.

If you live in a populated area you can check the stock at several near by HD and Ace.  If you are ordering via online it will just be a shot in the dark

This reply was created from a merged topic originally titled New 15" Trimmer ST1521S from Home Depot - How to get battery with fuel gauge ?.

Purchasing a new 15" String Trimmer ST1521S from Home Depot and was wondering how I can be sure to get one with the new Fuel Gauge Battery? 
Any dates or serial numbers on the box to look for to make sure of receving this newer style battery with the fuel gauge?

As some have mentioned above, it's not the serial number that ends in T, it is the part number that ends in T that indicates if it's the Gen 3 battery. 
Part number, not serial number. 
I have the new mower and it came with a 7.5 ah Gen 3 (T) battery and I don't recall if the fact that it was a T battery was mentioned on the box.

Same thing. I just got one and battery is dated Sept 19. I waited to buy from last year so I would get the fuel gauge. I guess I'll have to return it

Why do you need to return it ?
