    Overall I am Content the only reason why I did not give a 5 star rating is because the battery is actually much smaller than the battery it replaced.. It starts up my ATV just fine and that’s all that I needed.

    Perfect match up for a 2005 Kawasaki kfx400… terminal screws could be an eighth of an inch longer but oh well

    I bought this battery for one of our ATVs 5 months ago and it’s still working just fine. I’ve bought these Mighty Max batteries for our other ATVs and jet skis and they have all served me well.

Excellent
Mighty Max Battery
Based on 5640 reviews
So far so good
Fast shipping
Ordered it on Amazon and it arrived the Amazon usual one day after posting. The packaging was over the top plus inside a stuffed Amazon box. Ordered it for slightly less than the OEM battery and this is above that in specs. I did have to make longer tiedowns but no big deal.
Bought this 320 CCA battery to replace my 11 year old Mighty Max deep cycle battery on my Skag FreedomZ ZERO TURN. If I get that type of lifetime from this battery it might be the last one I buy. Mighty Max might want to consider planned obsolescence.
So far, seems to be working great on my jump pack.
GREAT SERVICE ON BATTERY FOR MY STANDBY GENERATOR.
Order, delivery, install all as promised and all good
Exact fit and works as expected
MightyMax battery has been a great battery so far.
Love how many items I can charge at the same time. No more searching for the correct chord and charger, all in one place.
