    You should not use USPS for shipping – the box was crammed into my small mail box and it took 10 days to get here. I have not installed the battery in my snowmobile yet so time will tell if it is a good battery.

    Haven’t had any problems with these batteries previously and have bought quite a few but I bought two new ones and one of them was completely bad right out the box. Other than that no problems previously

    Not sure how long it will last, but fits as it should and seems to work as expected. Bought for a can am side by side and it starts it easily.

    This battery is just really nice worked well for my jetski and was much easier to install than other batteries bcz it has a groove for the metal piece u screw into.

    My 2007 Grizzly ATV died and all it needed was a new battery. This battery worked perfectly.

    Battery fits well, been using for ~6mos, no issues yet. Would have given it a 5 star but the terminal blocks are very cheap/flimsy. Be careful when tightening…

    I have an old Yamaha Grizzly 660F (I think 2003). It had sat for 18 months without being started, and the battery was completely dead and could not be revived. This fit very tightly in the battery compartment, but it had enough juice to get it to start and it was not easy given how long it had sat. It arrived the next day after I ordered, and seems to be a great battery.

    Second battery of this model I have purchased. Lasted more than a season so has definitely outperformed others.

    I ordered this for a Seado Spark. its the only battery I could get on such short notice before the weekend had hit…so my daughter could use it for her Bday.Im wondering if I got the wrong model number ass the terminals were reversed. Positive was on the left vs the right on the stick battery. Luckily the leads were long enough. Had a full charge and has worked all this past weekend so no complaints.Like I said I will need to check to see if the model number was correct but it did work luckily. Will update If I run into any issues later on.

Good price...about half of the big brands... performance is good...I am happy with the purchase.
