  1. John –

    I haven’t used battery and I’m sure it’s fine. My customer ordered one also so I wanted to return this one but it says I can’t return because it’s a battery that can’t be sent. It was sent USPS so why can’t I return it using USPS??

  2. J. Harris –

    It’s a good value so far, we will see how long it lasts

  3. Nunya Bidness –

    The Chamberlain battery that came with my garage door opener lasted for 4.5 years. I replaced it with this battery and the Mightymax ML5-12 battery lasted for just over 7 years. I am ordering a new replacement battery and will be buying the same brand and model again.

  4. LMF –

    Used on a 1-1/4hp Chamberlain garage door opener.

  5. John Kuhfahl –

    perfect

  6. Penguin –

    It works great so far.

  7. cpickman –

    I cannot comment on the longevity of this battery since this is the first time I’ve used this brand to replace the factory Chamberlain branded battery, however, it fit perfectly in the battery compartment and connected to the garage door opener without any issues. Very pleased that I purchased this replacement battery since it was half the cost and it was immediately available for delivery unlike the Chamberlain replacement battery which was two to three weeks out.

  8. teddybear Knoxville Tn. –

    Installed it fired right up plenty of power.

  9. Web Customer –

    Garage door

  10. Earl L Lord –

    It was the correct battery and fit OK.

  11. Nancy –

    Garage door opener battery died, this one was a lifesaver. It came in quick, easy to install and not expensive.

  12. Fuzzy –

    It’s a battery, it fits, it works. I go thru these every 3 years and have low expectations for this one last any longer.

  13. raj –

    No comment

  14. Andrew Lai –

    Great replacement option. Have none local for me, so no choice but to get one online. Installed easy and was fully charged by the next day.

  27. Bertrand Waché –

    Decent value. When we lose power for a week, the battery does not seem to be able to handle things properly. What’s the use? Not a good backup.

  28. Anonymous –

    Decent value. When we lose power for a week, the battery does not seem to be able to handle things properly. What’s the use? Not a good backup.

  29. Calvin Miller Jr –

    So far so good works good just what I needed.

  30. PatrickF –

    Good value and arrived on time

  31. justin –

    Needs to be packaged better.

  32. Hailu Beyero –

    Garage door battery

  33. Vickie White –

    Battery starts working right out of the box

  34. RLew –

    The stock Chamberlain battery was rated at 4.5 Ah and this being 5 Ah is rated higher. I am pleased by the price and the ease of install of this replacement battery. The stock battery is a bit heavier than this, so time will tell as to the longevity. I got 8 years from the stock Chamberlain battery until it started beeping at me to replace it. Fast shipping too.

  35. TK –

    This replacement for the Chamberlain battery was a perfect fit. It arrived on time and was well packed. Only gave a 4 rating for longevity because I installed it only a month ago. Hopefully it lasts years and I can give it a 5.

  36. willy –

    Lasted roughly 4 years. It would be nice if it would last longer. Easy install

  37. Customer –

    Just installed cannot judge longevity

  38. 40Habits –

  41. Shirnett B. –

  42. Teddy M. Aponte –

    I bought this battery for the garage door.

  43. david bird –

    much cheaper than the opm battery

  44. ED Soliman –

    good product and price

  45. Stan Walters –

    Quick delivery. Easy installation. Right size. As for durability can?t say as I haven?t long enough. Would buy again.

  46. Clinton Massey –

    The battery was a little lighter then the original battery. Not sure if that will mean is has less power or will have a shorter life. I bought this for a back up battery for my garage door opener. It fit just fine and my ?bad battery alarm? finally stopped.I got this one because it was cheap, but that was the only reason. I would recommend this if you have the money going OE would be the best because you know how long it will last.

  47. Speedy Electron –

    We got almost exactly four years of life from the same make/model of replacement battery for the original Chamberlin one (which goes for more the 2X) For this price point, that was good enough for us to order another as replacement.Now if you are here I’m sure you know the life of the battery is somewhat determined by the Chamberlin unit . Once it decides the battery needs replacing, it begins to beep. Not as bad as a Smoke Detector but close to it and at least it’s in the garage….still irritating.

  48. Tony –

    It was easy to install, and seems to be working as expected for much less $.

  49. Adam Brown –

    It?s a direct replacement for my garage door opener. In 5 years I will buy another one to replace this one. No complaints.

  50. Dorothy Hughes –

  51. Bruce S. –

  57. Peter –

    Way cheaper than the Chamberlain version, works exactly the same. I have bought 3 of these (they only last 2 years or so)

  58. Customer –

    Bought this battery as a replacement for a Chamberlain garage door back-up battery. The original lasted a little over 5 years. This Mighty Max battery only lasted a little over 2 years.

  59. BOCA RICH –

    As good as it gets….works great. Less expensive than the original battery which was also made in China

  60. ARG –

    exactly as expected, great charge so far

  61. Comdoc –

  66. Carlos –

    Works great

  67. Customer –

    Works great

  68. Customer –

    This product is a perfectly capable replacement for the OEM battery. The dimensions are perfectly compatible, and it comes with the proper lead. When mine yeah, I noticed the battery leads at Walmart, and the entire project was fully sealed unlike some other vendors. I took probably as much time to install, as it was to order- virtually none at all.It’s been installed for over a month, and I have tested it several times. I have no doubt that this battery will continue to operate at least as long as the OEM battery.

  69. Kenneth Stanley –

    This item was delivered quickly. It was a an exact fit, form, and function replacement of the original battery. It was half the price of the OEM replacement battery.

  70. John –

    Prompt delivery. Battery working great.

  71. Customer –

    Yes

  72. startreker –

    Fits perfectly. Fast delivery.

  73. Pecan –

    Works great, easily installed.

  74. Customer –

    Fast service, does everything as well as original,fits better, costs less. What more could any one ask?

  75. Gerar –

    Perfect works great

  76. Mike –

    Plugged it in and works just fine. Let’s see how long it lasts.

  77. BLEdge –

    Great battery

  78. may –

    This battery is exactly what I needed to stop the annoying beep noise that my garage door opener made when the old battery died. This is my second battery replacement in roughly 10 years, so I expect to need another in five years.

  79. Chw6586 –

    Works in garage door opener. Easy to install

  80. Count On My Review –

    This is a great replacement. Buy it.

  81. Einpton –

    This battery is an exact replacement battery for my Chamberlain garage door opening but at a fraction of the cost. It arrived in 3 days and I installed it in seconds. It has only been 3 weeks, but so far so good.

  82. Alex Yovorsky –

    Just what we needed for the Garage. It’s a back-up system battery. It came when it was scheduled and a very fair price too.

  83. Customer –

    Looks good.

  84. Scott R Turnbull –

    I was happy to buy it. It was easy to find and put in, but as it is a backup battery for my garage door, I honestly hope to never acutally use it.

  85. T. Thomas –

    So far so good

  86. Jack Jones –

    A good product at a reasonable price. I would buy again.

  87. Michele R –

    Worked great and came quickly

  88. Customer –

    Works great and the price is fair too!

  89. Gustavo Torres –

    Very cheap and effective.

  90. Baron Haner –

    Direct replacement for our Chamberlain door opener

  91. Alan K –

    Great replacement for the Chamberlain battery. Perfect Fit. Longevity is unknown. Has been in use for a month and tested weekly.

  92. Kris V Murthy –

    Good product.

  93. D. DEGEORGE –

    This is a compatible replacement battery, at a fraction (around 1/3) of the cost from Sears or Chamberlain. While only time will tell about the durability of the battery, I have to note that it would not have to last more than 3 years to equal the life of the original. This battery, unlike some of its predecessors and competitors, fits into the unit’s battery compartment easily and connects to the wiring exactly the same as the original–no adapting of the terminals or additional wires needed.

  94. Armen K. Torigian –

    Shipping was quick and works great

  95. Edward M Potzmann –

    works great

  96. Joan M. Jones –

    It worked out perfectly for me, thank you very much

    Very impressed

  103. Dan Cavalieri –

    Good price

  104. D. Curran –

    Exact fit, same size as original battery. Just hope it lasts as long.

  105. Luv2Ski –

    Prompt shipping and good packaging. The Mighty Max fit just a tad snugly in my Chamberlain GDO which is now happy and working again. I let the old battery get so depleted that it apparently caused the wireless receiver to forget the remote codes. After replacing it with this battery and reprogramming/relearning the remotes, everything is working fine now 6 weeks later with no problems whatsoever.

  106. Rob –

    Needed a replacement for my whisper drive Chamberlain garage door opener. Seems to work just fine. The OEM battery lasted 7 years.

  107. Jeff M –

    Plug and play compatible with my Chamberlain door opener.

  108. Jimbo –

    delivered as promised and is working fine

  109. Customer –

    Worked perfectly! Thank you for you quick response??

  110. Nocturne –

    This was a replacement for a Chamberlin garage door battery that had to be replaced. The battery was packed well, with lead covers to protect the leads from becoming bent during transit. I’m not able to assess it’s longevity or its ability to sustain enough charge to open the garage door several times if the home power is interrupted. However, given the quality of the battery exterior, clear writing on its side (inferior products often have misspelled words, inattention to quality of the print and information), and packaging, with contact from seller asking if the product was what I wanted, I respect their desire to produce a quality product for the consumer.

  111. Shaun –

    Perfect fit for my Chamberlain garage opener. Hoping to a few years out of it. Way better than paying twice as much for OEM battery. Only gave it 4 starts cause it is not OEM battery

  112. Aly –

    I was glad to find this battery. The price is very reasonable. My last battery lasted 3 years. I like knowing that if the power goes out, I can still operate my garage door.

  113. H. Hover –

    Great so far, haven’t had a power outage to truly test it yet though

  114. Lawrence W. Olenginski C.R.N.A. –

    Just replaced, no problem.

  115. Beckie Wood –

    Battery arrived in a timely manner. Working just fine at this time.

  116. J Doyle –

    Replaced what I had with no issues and stopped my garage door opener from beeping.

  117. David –

    easy to install worked great first time, quick shipping.

  118. Mike Messer –

    SWEET NECTAR OF ELECTRICAL ESSENCE BREATHETH NEW LIFE UPON MINE OPENING DEVICE. PRAISE EDISON FOR DC LIFEBLOOD!

  119. Ingrid P –

    This battery matches the original and works well for about half the cost.J. Price

  120. senoraCAS –

    We’ve had this battery in place for several weeks. Fit well. The test will come during our next storm and power outage. Hope it last longer than the last battery so I can only give it a four star for now.

  121. Edgardo –

    Great product and is working great.

  122. golfmajor –

    Fit perfectly as a replacement for the Craftsman battery in my garage door opener and was about $20 less than the Sears recommended battery.

  123. Lloyd D Ross –

    works great

  124. Lawrence L Greenwood –

    I liked the battery very much. and it does the job for me.

  125. D. K. Numinen –

  126. TS –

    Perfect fit for my garage door opener.

  127. Bobby –

    The replacement battery was an exact match to the original. I removed the old and installed the replacement quite readily, including connecting the push-on garage door opener’s wiring connectors. The battery charged immediately started to charge, meanwhile the garage door opener worked perfectly. The new battery was fully charged in 24-48 hours.

  128. GAIL H –

    Great. works fine.

  129. Bill R –

    arrived quickly , fit good and no problem’s so far

  130. Sharon H. –

    My garage door opener started beeping–signaling that the back up battery was going dead. I checked my local Home Depot and they didn’t have any available. So I went to and found just what I needed. The shipping time was good and the install was simple.

  131. Robert F. Jakubiec –

    easy installation, perfect fit replacement battery with lower price than the brand name one. Great buy!

  132. Brian P. Sullivan –

    One of the few things in life that just worked without hassle.This hardest thing was getting the ladder into the garage.

    Great price and worked right out of the box

  138. oldpoet –

    Arrived as promised. Working well.

  139. GMK –

    The price was so low that I was a little hesitant. It came super fast, and as soon as I popped it in the relentless beeping stopped. Very pleased with the battery and company and the next time that garage door opener starts to beep, I’ll gladly order another.

  140. Ed MacKenzie –

    Exactly what I needed at a great price and good shipping.

  141. arthur everly –

  144. Super Genius –

    Half price and shipped so damn fast

  145. L V –

    It fit just fine. The red charge light on the Chamberlain garage door opener stayed on for at least 24 hours, then it turned green. Indicating a full charge. I have not lost power to try it out.

  146. Fearnando –

    Battery was a perfect fit and works flawlessly! This is a great value product.

  147. James G. Feick –

    This battery works perfectly. The fitment was perfect and was an easy remove and replace of the old battery. It took about 24 hours for the new battery to get a full charge.

  148. richard evans –

    worked like a charm

  149. Dean –

    Just what I was searching for.

  150. Laurie S.-Homosassa, FL –

    It is not something that I would notice working every day. It is a back up battery. The next time the power is out, it will either work or not! Right now, it fit in its compartment and I am happy with my purchase.

  151. Mark, Port Charlotte, FL –

    It is not something that I would notice working every day. It is a back up battery. The next time the power is out, it will either work or not! Right now, it fit in its compartment and I am happy with my purchase.

    worked fine

  155. bettnott –

    We used this battery as a replacement for the beeping one in our Sears garage door opener that we purchased about 3 years ago. The battery arrived quickly & it fit perfectly. It looked like the battery we pulled out. Another reviewer stated she could not tell if it had the same specs as the original battery, but the battery we received was clearly marked with information & just as pictured on the site. It has been in place now for about 3 weeks, so time will tell about its sustainability. Very pleased with the purchase.

  156. Jmarshallsea –

    Did the job

  157. Jackie C. –

    Great battery! Shipped quickly and fit correctly. Wonderful seller. I have bought from this seller before. I will purchase again. Also fits my sears garage openers and my alarm system at my shop.

    I purchased this battery for my garage door opener a few months ago. It has been working perfectly and I have had no problems with it, hence I gave it 5 stars.

  166. S J –

    I worked fine. Getting into the garage door opener itself was not fun! But my husband did it.

  167. Customer –

  186. William –

    Great bargain, just what we needed

  187. Cyndy Clark –

    The new battery works. The replacement was quite easy except that the ground lead on the old battery was larger so the lead is not as tight as before.

  188. Jim Torrence –

    This is a great replacement battery. Essential during power outages (common in Seattle in the fall and winter). Easy swap. Less cost than expected. Works like the original.

  189. James A. –

  190. Douglas Carr –

    Battery worked just fine and arrived earlier than anticipated

  191. bob p –

    Got it sooner than expected and its fine.

  192. seinlin3 –

    Working as expected.

  193. Timothy J. Gallaway –

    What can I say? It’s a battery. It fit my garage door opener. It charged up. It works. It was 1/2 the cost of the same battery from the manufacturer of the garage door. Ta da!

  194. C. Lattimer –

    Got a dead-on-arrival battery that the Chamberlain opener could not charge. Figured out how to send an email thru to the company and they told me to keep charging it. After a week, no charge. Emailed again and Mighty Max immediately sent a replacement. This worked great — the opener accepted it, charged it, and it tested perfectly by raising the door when I unhooked the AC power. So took off a star for the dead battery but company earned the other four with great customer service.

  195. Jerr58 –

    Just what I needed!

  196. Lou Ratsos –

    Priced appropriately and shipped quickly.

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.

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.
