    Mi cargador de baterías de carro quedó como nuevo

  2. Web Customer

    This Rechargeable Battery for Champion Generator 9000/7000 is very reliable and fits as expected. The price was excellent.

  3. TMan Services LLC

    The battery arrived well packaged and ready to go. Enclosed was a card to register with the manufacturer and receive three month extended warranty. Their website collected my info but never received the email verification. I also emailed their customer service but no response. The battery works. Most likely it’ll work well past their mfg warranty. Fingers crossed!

    As described, the same for my champion 6000w Generators. Easy to install. Will keep on a battery tender until needed. Hopefully it will last 10yrs like the original. Also same battery as my jumper box.

  82. Richard J. Bendorf

    I have 5 UPS units that I use on various servers and desktop computers. I have installed the MightyMax ML18-12 batteries in my older APC Smart UPS 1500 units and they have operated perfectly. Each unit takes 2 batteries, and I have hot glued them to together just for stability. I would recommend this as an excellent replacement battery for the Workhorse APC Smart UPS 1500.

Mighty max brings the battery backup back.
Arrived well packed in unopened sturdy box. Was replacement for identical Mighty Max battery I ordered 2 years ago. Taking 1 star off because didn’t include the needed terminal clips - was able to use the old battery’s clips
Same model fits in each of our four wheelers great product
Replacement for my Murray MT100 riding lawnmower. Murray does not make replacement batteries and you are on your own if the battery goes bad. Bought Murray MT100 in 2023, battery went bad in 1 year and all other Murray replacement batteries are LARGER so it won't fit.This Mighty Max Battery fit the MT100 fine and it starts it perfectly too.
Direct replacement for generac portable electric start generator. Works great.
Received really quick. Boxed well and fit great. Worked like a charm! I would definitely recommend this battery.
As an athletic trainer I rely on our water units every day to provide the water to our athletes. We have over 900 student athletes enrolled, and these units get used daily, so it is imperative these batteries are reliable. On a side note, I also use these batteries on my fishing kayak to power my fish finder. I can use my fish finder for about 20 hours before it turns off. These batteries are great! Highly recommend. I have not had any issues so I haven't spoken to customer service yet, but if they are as good as these batteries have been, I think I am in good hands.
Needed a replacement battery and the manufacturer wanted $50 whereas you only required $20. Made it worth it!
satisfy with price and easy installation.
Arrived in great condition comes with the bolts to attach the wire over all very satisfied
