    It was a perfect fit

  4. Invaluable

    We have a Toro push mower about 15 years old and the battery has been dead forever. Got this battery it was a direct fit and mower started the first time. Can’t comment on longevity because I’ve only had it for a day.

    Popped the old battery out, put this new one in, and *voila,* my APC works again. That’s all I was looking for. Well, that, and a better price than the OEM.

  7. Christopher Arkwright

    it fit my mower. Fast delivery.

    WALK BEHIND TORO SELF – PROPELLED LAWN MOWER.

  9. Chez

    Battery does better than the original.

  10. mizwithme

    Bought it to replace aged battery in Uninterrupted Power Supply. I had to chisel out plastic brackets in the UPS housing for the battery to fit, but now the UPS works and can accept a real generic size battery.

  11. ICETRAINS

    Direct replacement for APC ES-350 UPS, helped bring an old UPS back to life. One caution: If your UPS is not plugged in to the mains, there is significant discharge on the battery at no-load, but is able to recover quite fast upon connecting to the mains for 20 min or on a automatic trickle/float charger. Overall good value for the price. Happy with this brand and this a third type of battery I have purchased over past few months.

  12. j-keenan

    Direct fit replacement for APC battery.

  13. JMO

    These replace previous batteries from the same manufacturer that were 4 years old. For the cost, the longevity is great. I will continue to purchase these.

  14. Dale E. Ferguson

    Exact fit, I have purchased numerous batteries for UPS, etc. (Mighty Max brand) All have been a perfect fit.

  15. John Kirk

    Bought this battery for an APS ES-350 UPS. UPS works well now. I have used Mighty Max batteries in the past and they have always worked well and provided good value.

  16. little auggie

    I used 2 of these for a Chamberlain garage door opener. The batteries fit perfectly and work fine. You may need to get new terminals for the wire ends or solder them to the battery. I soldered them. Great price for a good battery.

  17. Shady Brook

    I have bought several UPS batteries from Mighty Max over the years. The one time I had an issue, they quickly sent replacements. Can’t beat the value for the price.

  18. Web Customer

    Worked great for my Toro Mower

  19. Jack Fergus

    My Battery died in my Toro Lawn Mower after 8 years. I bought this one and charged it up overnight. I started my Toro with the key and it turned over and started lightning speed.

  20. Nayan Patel

    Okay quality battery. I bought it because of Price was attractive. Original battery lasted 3.years.

  21. Web Customer

    Perfect

  22. Cortney Brown

    Very good battery for half the cost

  23. The Reverend A.J. Miller

    Very pleased with this purchase. wires are color-coded and have good, tight connectors. Currently have a laptop, tv, and external hard drive attached. Did have a bit of worry at the beginning when first attached, as the U.P.S. showed a building wiring fault light, but it turns out that the wall tap the U.P.S. was plugged into was not properly grounded.

  24. Web Customer

    Works Great!

  25. Tim R.

    Works as it should, wish it was cheaper.

  26. RCC

    It’s got the correct electricals ratings, and I’m sure it works as intended, but it’s physically too long and prevents the battery cover from latching. Unfortunately I don’t have the old battery to compare dimensions.

  27. Alan C Wilson

    Battery works as expected. Liked the price!

  28. Donald Behrens

    Price is right, the size is right and it works perfectly in my APC for my computer.

  29. Donald Behrens

    Price is right, the size is right and it works perfectly in my APC for my computer.

    As Advertised

  31. R. A. Moore

    Don’t throw away your UPS just because it won’t hold a charge. Replace the battery and save yourself some real money$! I have 2 Cyberpower 425VA UPS units one older and one newer. Both needed new batteries. the older unit I had to modify to make this fit (had to carve out some plastic) but it does definitely work. the newer one just dropped right in.

  32. krakowmike

    Battery on APC we use went out and this is a direct replacement to make it work again. We repair items that go out and do not replace when possible. Battery cost was much cheaper than a new APC unit.

  33. Machdr

    Wanted to replace the 8 D cells in my granddaughters water bumper boats that seemed to need constant replacement. The battery fit perfectly in the compartment with a plug in I made. Also set up to recharge without disassembly. Works great and lasts all day. Both batteries cost less than 16 D cells and rechargeable !!!

  34. Paul R Crow

    Solid replacement part at a great price point.

  35. Paul R Crow

    Solid replacement part at a great price point.

  36. Anna G.

    This battery works great and is easy to install. I was charging my Black and Decker CST1200 Weed Trimmer for an hour to only get 3-5 minutes of weed eating done. This battery has brought it back to life.

  37. DHO

    I don’t know why so many people throw out UPS units when the battery dies.A replacement battery is cheap and get it working good-as-newEasy swap out. No issues. Works great

  38. Ron L.

    Replaced a 12 year old electric start lawn mower battery. Plugs in the same as the old battery, cranks fast and starts right up. Hope it lasts another 12 years.

  39. Vincent Price – NOT

    I purchased this to replace the 3-year-old battery in my APC ES350 ups. This battery fit perfectly and after installation, my UPS recognized the battery and stopped beeping.I had discovered that the original battery that came with my APC UPS is actually just a third-party battery that has an APC label put on by the UPS manufacturer… i.e., the internal battery seems to be made not by APC but by third party companies. So I saved a few dollars by purchasing this battery instead of a replacement that’s marketed by APC itself. was quick to ship, and the battery was in good condition when I received it.Overall, worth the purchase.

  40. B

    This is such a good buy for the money. Once I got the weed whacker opened up it was really easy to install. It worked right away and brought my weed whacker back to life.

  41. Frederick Martin

    Would order agaiin

  42. Momscoming

    what can I say. its a battery. took a bit of time to get here but it is working fine.

  43. Mighty Bros

    fast shipping, works great!

  44. JKVStang

    Just as expected.

  45. Al Bacas

    Everything went fine.

  46. Jon Freivald

    Perfect fit. Performs well. WAY less expensive than the OEM replacement.

  47. HaulinAshe

    Excellent replacement for my ancient Craftsman weedeater. Batteries Plus said they didn’t stock that type battery and could not order it. I saved a bundle on the batteries. Very satisfied customer.

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
