  16. Zachary Vincent

    Decent battery. It lasted about a year on my atv when it gave up. Perfect fit but I just upgraded to a big lawnmower battery so I’ll no longer need to worry or have to get a push start or jump

  17. BOSS903

    Great price! Fit perfectly would buy again!

  18. Jessie Martin

    Proper fit

  19. Troy W.

    Just had to buy another one. The first one only lasted 4 years here in Alaska. LOL. This is the only battery that has lasted more than a year in either my 4 wheeler or snogo. I always disconnect the battery before winter storage but all others die before spring. This battery takes the extreme conditions I have here in the Alaska Range. 40 to 50 below and the snowmobile still starts easy. By far this is the best atv battery I have owned. I will continue to buy them.

  29. Customer

    I read other reviews where the battery had to be placed on a block of wood to support it, but I ordered it with the hopes that just maybe. Please note if you order this battery it may not replace the original oem fit battery. For some a block of wood supporting the battery will work. I prefer things be secure on my Honda Foreman and a block of wood holding up a battery is not ideal. The battery seems ok and the price paid was reasonable. The battery charge amount was right on when it arrived. Haven’t installed while I look for a true replacement if there is one to be found. If none found, I will fabricate a mount for the battery to securely sit on.

  30. Jerry Lynch

    Starts my Polaris 330 well the fitment not so great but for the money very pleased

  31. cjeff13

  32. Wyatt furman

  34. Jerald Grant

    used this battery on a generator and it has preformed flawlesly

  35. Customer

    Product worked fine and I did not have to add the acid to the battery.

  36. Ranchhand

    This battery is a great value, as the price is very competitive with WalMart, where I have in the past purchased replacement batteries for my ATV’s. Delivery to my home was ahead of schedule. This battery is sealed, a great plus, and has plenty of power, despite being smaller than my prior batteries. I just placed a short piece of 2 X 4 under the battery to raise it to facilitate wire connections. My only criticism is that the connection posts are deep, and when connecting the battery, you must put a shim under the nut to get it to thread on the screws provided. Nevertheless, this battery deserves a 5-star rating. I highly recommend this battery and the seller.

  37. brivander

    I bit smaller than the original battery size on 2002 Honda Foreman so I used a small piece of wood to shim it up, but for $30 it’s an amazing deal.

  38. Mark diamond

    Works like a champ. Great price.

  39. Vincent cruz

    Works great on my ltz400

  40. Ruth Creighton

    It fit the hoda 300ex perfect and works perfect. I waited until it was used a lot before writting this. It is a good product and so were the people I bought it from. Recieved in 3 days. Came charged only had to finish the charge and install it. It doesn’t come with electrolyte seperate, it comes ready to use. Very happy with it, specially at the price.

  41. Rick Allison

    Works great

  42. trmoto

    decent battery for the money i would buy again

  43. BC

    Fit perfect in my XR650L. Works good. Only time will tell how long it lasts but it’s off to a good start.

  44. Travis Mast

    its amazing to have the 4-wheeler start up so easily! great battery for the money. it really seemed to ship fast. We have only been using it for a shorty period of time so I can’t speak to the longevity of the product but so far we are very satisfied. I really seems to have done the trick. I am hoping this battery lasts longer than the last one. It may the the age of our machine but the last one only lasted a little over a year. Easy to install. Nice looking for a battery.

  45. Shannon Mosby

    Item was a little big for my 2001 bayou 220 so it was extremely snug in battery compartment. Was still able to make it fit and worked great

  46. Mike Rice

    So far it’s started my bike every time even when the temp. dropped below 30 degrees outside and that’s something the old batter wouldn’t do.

  47. Dennis sahli

    Very happy fast shipping

  48. Nicole Phinn

    so far so good

  49. Sherri

  59. Simply Dad

    Battery fit perfectly into my 1992 Honda TRX300EX quad. After an evening on the trickle charger, the battery had a solid charge and fired up the ATV after many long minutes of cranking. My ATV has been sitting for over 2 years, so it was a little rough. Been riding now for a couple of days and the battery is doing fine. Very pleased with purchase.
