    The connectors on this new battery were F1 connectors, not F2 connectors like the listing said. This meant that the battery terminals were smaller than the connectors of the weed trimmer. I just pushed them on and they were tight enough to not cause a problem so far. I did not change the end connectors to a smaller size. I was still able to install the battery and it has been working fine for the past week.

    It fit exactly and gave new life to my very old weed whacker. Can’t give it 5 stars until I see how long it will last.

    Battery was an exact drop-in replacement for the OEM battery. Works as expected. Received before due date.

    Great product and a perfect fit. The battery holds its charge and lasts a long time; at least 1.5 hours during my last use. This battery saved me from having to throw out and replace my trimmer. Thanks guys!!!

    I received the battery about a week ago, and everything seems fine.The size is as stated and it fits my B & D CST1000 weed eater just fine. I don’t know what an F1 terminal is but it is a little smaller than a quarter inch terminal. My quarter inch connectors fit snugly enough though.At the time of this writing Mighty Max Battery has a no questions asked return policy. Since the price of the battery includes the shipping, if you do have to return it, you get all your money back. ( Less return shipping I suppose.) That makes Might Max Battery a good deal.

Very good batteries, i've had good experience with this brand. Bring back 2 ups just today ! Way cheaper than new ups.
Easy to install
Perfect fit. High quality item. Highly recommend.
I had purchased a Mighty Max Gel battery almost 1 year to the day of it failing, I contacted Mighty Max, and in a very simple process they warrantied the faulty battery and sent out a new battery. I definitely would buy another Mighty Max battery just because of their customer service.
Replacement for the battery in this. Over the years I've done exactly this a number of times.
Wonderful.
Couldn’t be happier with arrived battery.
Thank you.
So far, the Mighty Max YTX16-BS battery has worked as expected. It arrived from Amazon and delivery was quick. I needed a battery for my 4 wheeler fast and at a better price than Oreilys, Walmart, etc.
Easy to install
Works great as always ...mounted to a generator set up for easy start works just as it should
