90 reviews for ML8-12 – 12V 8AH Replacement Battery for APC BACK-UPS BE750G 750VA

  1. Broyer

    Secure Packaging. Fit my BE 750 UPS perfectly. Build quality seems as good as other more costly ones. Will of course have to see about longevity but I have no reason to believe them of inferior quality. Would buy them again.

  2. SS in FL

    Quit working in my APC 750 VA after about a year.

  3. gary b

    Exact fit works good

  4. Samuel Rodriguez

    A perfect fit for my version of APC backup unit

  5. Offer Shamir

    Wonderful battery replacement for my UPS.

  6. Randy

    Ordered for a battery backup. The measurements matched perfectly to the old one. I haven’t lost power to see if it will hold up but I’m sure it will.

  7. AllenC

    I currently have 3, APC Back-UPS BE750G, backup units for 2 computers and a Multi-Media system. After several years of use they require replacements batteries. I replaced the battery in my oldest unit 3 years ago with this same Might Max battery and bought this latest battery to replace it. My other 2 identical units are on year 2 of this same battery replacement and will be replaced in another year. So far no problems with any of the replacements. The battery terminals are a little thinner than the APC originals and the battery lighter, but it’s an exact fit in the unit and the terminals connect same as the OEM. Overall a good replacement for the price.

  8. Customer

    Exactly what I needed… At a much better price!!!!

  9. Johnnie Martin

    First battery arrived damage in the mail. 2nd(Replacement) battery arrived in excellent condition. Only issue with the battery is the width of the terminal lugs (Both + and -). The terminal lugs on the new battery are approximately 1/2 the size of the lugs on the old APC battery. They work. Just have to be careful hooking them up and not disconnecting while installiing the new battery.

  10. Athabasco

    Installing the new battery was simple. Everything fit my old BE750G perfectly. Life span of the battery is yet to be determined. I downloaded the latest version of the software which works just fine with the older model unit.

  11. Joe R.

    Seems to be everything they claimed and is working great in my UPS so far. Overall, I’m pleased with this purchase and transaction.

  12. Paul D. Tyler

    This item has done well as of this time. It fit my case exactly as it should. I have read reviews about the terminals being too small and the wires would not stay on. I did not have this problem. They clipped on just fine and stayed attached without any problems.

  13. RLS

    Replacement battery for APC Back-UPS BE750G. Terminals were 3/16 instead of 1/4, but still works.

  14. Eddie Davidson

    Excellent product, fit, compatibility, ease of installation.

  15. S. Heintz

    Exact replacement came fast no problems very satified

  16. burntroach

    Love it. Great value for money fit rite in my apc ups and working fine. Def worth it. Shipping was a bit slower but it was worth the money saved instead of buying apc battery

  17. Bubba Ker

    It holds it’s charge and provides a steady current.

  18. Austin

    Our UPS battery died and this was a cheap replacement considering ours was an older model and the on-brand prices have increased. Installation was simple and the product appears to work fine.

  19. David

    This battery works perfect. I used it in an APC power supply for computers and technical equipment. Great value!

  20. Customer

    Quality Battery, UPS is now good as new.

  21. Victoria

    I am very happy with it. Installed easily.

  22. Michael Ellison

    Works as it should. Easy install.

  23. Janice Rapier

    This is the perfect replacement battery for my APC Backup Power. The battery is inexpensive and lasts for years if properly charged and used as directed. I only use the backup power for my computer. All other accessories are plugged into the surge protection outlets on my APC to prolong the battery life.

  24. Steve O

    Saves you bucks from purchasing a new UPS for your computer. It can be a bit trick to install on some models though as the different brands somewhat limit their access due to enclosure size. Not the battery but the wire length in a tight space situation. Great buy though!

  25. Astute Shopper

    Bought this item to replace the original battery in an APC Back-UPS ES 750. Perfect fix and is working as expected.

  26. Customer

    Fit perfectly. Great for the price

  27. Jazz Guy

    At first you worry about buying the generic or non-brand replacement batteries, but I have bought several of these Mighty Max replacement batteries over the years, and they seem to last a long time. I put dates on the battery case when I make the replacement, and I know how long they last. Good value.

  28. Thommygunner

    A+

  29. DrE

    Works well and fits well

  30. Larry

    Perfect fit and computer is up and running again. Recommend this seller!

  31. J. Buenfil

    Very easy to swap out with the old battery.

  32. KTratt

    Decent battery fits well. Great price

  33. Charles Alter

    Replaced battery in surge protector. No problems yet so can’t determine longevity. Great price!

  34. Bubballoso

    worked as expected

  35. Customer

    Installation was very easy and less expensive then purchasing the entire battery backup, when only the battery replacement needed to get the backup back up and running efficiently.

  36. GH1

    This battery was a perfect replacement for the original APC battery at a much cheaper price. Unplugged old one and plugged in new one.

  37. Waynemia

    First- the terminals on the battery did not match the plugs on my APC UPS. The battery was specified as a direct replacement for the one that was in the UPS. I contacted the seller and they sent some adapters. I appreciate the adapters but they should just include them with the battery if they are going to market as working with my APC unit. The battery size and capacity does match the original battery. The new battery is working fine. I cannot evaluate the battery life as it has only been installed a couple of months and it should last for years.

  38. Chris

    Has small terminals, I read it had the normal larger UPS size spades.

  39. RPM360

    I received the battery a couple days earlier than the estimated delivery time – good! Battery was easy to install and met the same specs as my old battery. I let it charge (over night just to be sure), then did a power fail test and the battery held up for the time I estimated based on my load on the UPS. I would buy it again.

  40. Vickie

    Fit my UPS backup BE 750 perfectly. Reserved a star because I haven’t had opportunity to test it out yet. It’s charged and ready to go.

  41. Risenheart Consulting

    …saved my big bucks replacing the battery over a new UPS. I used to buy a new UPS because lets face it APC’s batteries are almost as expensive as a new UPS. Found these and have been using them ever since. In the last 6 months I’ve replaced 3 batteries in 2 UPS’ that finally died after 2 years. These batteries work great and are far cheaper than the APC batteries.

  42. Jeffrey B

    It’s good to see a company that stands behind their product. When the first battery failed Mighty Max sent me another. The replacement battery appears to be working fine.

  43. LARRY BATEMAN

    Fit charged and is working

  44. Customer

    Took right care of my problem with my ups

  45. ThinkGeek

    works great fits fine!

  46. S. Greco

    The battery fit my APC Back-UPS ES 750 Battery Backup (Model BE750G). Connected easily (had to remove the clear connectors at ends of positive and negative wires to connect). Works fine thus far.

  47. editus

    I got the battery and it fit the UPS fine. It charged up quickly and the UPS is working as expected.

  48. Paul

    Came in a timely fashion, fit perfectly as a replacement in mt APC power backup

  49. M. Tanner

    Great product … would definitely buy again

  50. online shopper

    I got an battery which seemed to work, but only delivered roughly 15% of the advertised 8 Ah when I ran tests on it. I found it 2.5 months after my order, which was outside the 30-day return window. Mighty Battery offered to replace it with a fully tested battery, so I am waiting for the replacement now.My load was 12-13 watt, and the battery only lasted for 1 hr 10 min. For a 12V battery, this is 1.1Amp * 1.2hrs = ~1.3 Ah. I know this was through a 110v transformer of a UPS, which maybe has 20-25% loss, but this still does not explain a factor of 6 of actual capacity vs. advertised capacity.For comparison, a 4.5Ah battery from a new APC UPS has lasted me 1.5 hrs on a 16 watt load, which is roughly 50% more actual capacity in a battery that is advertised as 4.5 Ah! (and the one being reviewed here is 8Ah).At any rate, will see how the replacement performs.

  51. Pete Ruttman

    We are currently using this battery due to a block power outage. We are sitting in the dark but, thank God, we have Internet!

  52. Ralph L Papenfuse

    Very good buy. Works as advertized.

  53. Jason P

    Replaced Verizon Fios battery.6 months in, still going strong.

  54. Rover

    Fits well in my ups and works as advertised

  55. FurryFriend

    Great replacement battery!

  56. David Bower

    Installed and operating perfectly. Only time will tell about its service life.

  57. Rich B.

    Good replacement battery at a good price. No issues. Easy installation.

  58. Joel Saunders

    Decent price, prompt shipping, good packaging, and it works great.

  59. Dennis R. Hughes

    fine

  60. Willie

    Works like a charm at a fraction of the cost of a factory advertised battery!

  61. Customer

    great replacement! I will get more in the future.

  62. Hawaiiguy808

    Great deal, works! Reasonable, fast shipping even to Hawaii. Much cheaper than the alternatives and most wouldn’t ship to Hawaii despite listing Prime shipping. Simple to install. Glad I did this instead of buying a whole new UPS.

  63. Adan Hernandez

    it revived my ups

  64. KentuckyBill

    Plug and play

  65. Nick

    As Advertised!

  66. dre

    Worked great with the UPC I got at a goodwill for 5 dollars.

  67. BILL

    Worked as expected.

  68. MICHAEL DePADOVA

    Fits. Works.. Have not tested the mAh. Volts ok. Best price, delivered when and as advertised.

  69. Lindell

    Higher amperage and 40% savings over the original equipment battery. The same theory I have followed with automotive batteries for decades.HERE IS AN UPDATE…We have 2 of these bought to replace originals in UPC Systems the oldest of which is almost 3 and a half years ago (June 2016) and doing fine. Since then in 2018 for another UPC and one for our Security System more recently as well. No problems of any kind with the very reliable Mighty-Max batteries.

  70. Paul D.

    This worked just as described. It is well made and arrived fully charged.

  71. Anton

    Worked as advertised for my APC battery backup.

  72. Be Oh Be

    Worked great. Plugs are a different size but seem to work just fine.

  73. Mike

    Worked well in our APC Battery Backup device.

  74. michelle

    Update: a month or 2 later, the replacement lost its charge as well. I decided to try APC (same brand as my UPS) – guess what, same thing happened. After emailing with APC we think my UPS is draining the batteries. I checked and it’s 9 years old, so I’ll replace it – and when I need a new battery I’ll go with Mighty Max again (the ones at work are still going strong).Initial review: Installed as a replacement battery in an APC Back-UPS ES 750. Worked for a couple of weeks then seemed to lose its charge. Mighty Max was very responsive via email and quickly sent me a replacement which has been running fine for 3 months now. The price is good and I’m confident enough in their customer service that I just ordered another set of batteries for my work UPS.

  75. B00M3R

    works great, just as advertised.

  76. cado2

    The Mighty Max Battery is working perfectly. I had no problem installing it in my battery back-up unit. The shipping was great, I received the battery 4 days after ordering. I would order from this company again with no hesitation.

  77. Customer

    This was a great deal for us. Best price, best quality, and the best shipping. I recommend this company for everyone!!

  78. RPL

    Arrived as expected. The contacts were a little smaller as stated in comments, but it worked just as stated in the comments. We lost power last night due to a lightning strike, and the battery powered the backup unit to perform perfectly.

  79. [email protected]

    working fine

  80. K. Knudsen

    Battery was a perfect fit in my APC UPS, at a fraction of the APC price. I can’t speak to how it will last of the long term at this point obviously. But it was a very easy swap and has worked perfectly for about a month so far.

  81. johncatl

    Don’t throw out that UPS battery backup. Get an affordable, quality Mighty Max battery for a lot less than a new UPS. Your wallet and the local landfill will thank you.

  82. John Rathbun

    Battery fit as advertised. Plug and play.

  83. Patrick A. Cooper

    It is a battery that does the things batteries do. And does it well…

  84. Stuart L. Maletsky

    Just worked perfectly right out of the box, no problems

  85. Jack-Way

    The battery arrived in a timely manner via USPS. The date code on the battery indicated that it was manufactured only a couple months ago, so it should have good remaining life. (This is good compared to previously purchased batteries from other vendors that were over 1 year old and did not last very long; SLA batteries have a limited useful life.)-The only negative is that it has 3/16 (0.1875) terminals which, while they fit the standard 1/4 (0.250) connectors used on my UPS, is truly not ideal.-Note: These folks offer a 12V 9Ah BATTERY APC BACK-UPS XS1500 RBC109 PS-1290 – 2 Pack – Mighty Max Battery brand product which I found to have standard 1/4 terminals. These batteries, each one being the exact same size as this battery, are cost effective assuming that there is a use for the other battery, not to mention being 9 Amp-Hours versus 8 Amp-Hours.- I would recommend to Mighty Max that they market their 9AH, 2-Pack offering as a single battery as it will fit in most APC UPS devices using this battery form factor. Also, Mighty Max is good as they accurately list the battery dimensions, however they should also list the terminal dimensions.

  86. Roy A OKeefe

    Don’t throw out that UPS. Just replace the batter at a fraction of the price!

  87. Gunda Corporation

    Was a perfect replacement for our battery backups and seems to be working just fine. Have only had it a month.

  88. Philip Youngholm

    Arrived quickly, fits perfectly.

  89. Customer

    Worked just fine in my APC-750 and cost way less than ordering directly from APC or of course buying a new UPS!!!

  90. Biofilm

    As advertised, an excellent battery, that fit perfectly, the APC battery compartments are a tight fit.I would recommend the Mighty Max Battery to anyone.

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
