    I put a charge on the battery as recommended, But really didn’t need it. Put it in my ATV, and off we went. No problems at all. Better and cheaper than OEM. Thank you

    Worked good. Bought in 2016 and worked until yesterday after I accidentally shorted it out while hooking up my sprayer clips. Oops. 4/5 because it’s a little low on amps. If your not over concerned with that then it’s an excellent buy for the money.

Mighty Max Battery
Based on 5595 reviews
I took this battery right out of the box installed it on my Honda rancher and first crank it started right up strong battery for a great price thank you guys!!
I ordered this for my generator. I ordered it off Amazon because it got here faster than ordering it from Lowe’s or Home Depot and it’s the same battery.
Gonna see how long it holds up.
Arrived promptly, packing was great. Exact fit. Easy 15 minute install in my Duromax Portable Generator.
Ordered and 2 days later received the battery and installed it in a ATV for my grandkids. the ATV started right up lot of power from the battery and all I had to do was pull it out of the box and install it. Also you get 3 months extra warranty by just registering the battery.
I'm impressed
Put the mighty Max Mighty YTX20L-BS Gel 12V 18AH battery in my polaris scrambler xp1000. Turns it over alot better. Got a brand new dud from another company. Should of stuck with mighty max to begin with
Great battery, great value, great warranty - looking forward to many years in my alarm system
Order the battery from Amazon came in 2 days installed no problem whatsoever for my matco tool jump box good service hope the battery holds up very well too
Battery arrived in perfect condition! Western house was the only place that sold the battery at the lowest price. It also helped that shipping was free.
I purchased my mightymax battery online model number YTX14-BS it was shipped to my house fast I was so excited to install this battery on my 2004 Honda VTX 1300c it fit perfectly. It turn on instantly, I will definitely recommend mightymax battery to all my friends and family.
Thank you so much!
