  1. John (verified owner)

    Delivery was within specified timeframe. Pay through Amazon worked well!! Have not had time to exchange batteries and charge them up. Hopefully, I will get the chance in just over a week!

  2. John Dunklee (verified owner)

    Received what I ordered in good time. Thanks

  3. BRIAN L. (verified owner)

    A great product at a reasonable price (if purchased in a bulk package) and pretty quick shipping as well.
    This would have been a 5 rating, but there was a bit of a delayed response (from the company), when I had a purchasing delay (on the site, using Amazon Pay) and it created a double purchase. That I communicate right away, but it took a little time to get a response. In the end, they rallied and more than compensated me.
    There batteries worked great for my application, in emergency lights/exit signs (as back-up power, when the electricity goes out).
    Thanks again for your help.

  4. John H D. (verified owner)

    Perfect fit, gave new life to my lantern. Works great.

  5. Awesomesauce!

    I replaced a old style lead acid battery that ran dry and definitely was not maintenance free with this sealed unit in a 1970 Honda Trail 70. It fits perfect and is holding a charge well.

    Used as replacement batteries for emergency lights.

  9. kernJJB.James PastDennis SchaubelGurvinder SranIgor

    Used in the old style quick pump. Came charged up and ready to go. Happy with purchase

  10. Expdealer

    Read some reviews saying it dies after a few days or it’s not for kids scooters, for me one month use still good.

  11. kernJJB.James PastDennis SchaubelGurvinder SranIgor

  12. Manuel N.

    Ok

    Thank you for the good battery,the toy is running again.Hope it will last for couple seasons.

  14. C Squared

    This replaced the battery for old style Coleman rechargeable inflator. Perfect fit, already fully charged on arrival. I would expect it to last as long as the original, about 5 years. Now I don’t have to get lightheaded inflating the mini swimming pool. Will buy again when necessary!

  15. kathy schmitt

    Our one grandsons motorcycle would not work and when you have two grandsons and only one working cycle it then becomes a fight between the two. This new battery restored the other cycle and they are back to riding instead of fighting

  16. Eva

    I bought this for my grandson’s electric motorcycle. It came charged. He loves his bike more

  17. Bob P

    I was sad when the batteries died in my rechargeable spotlight and my Coleman two bulb lantern. Both take this 6 volt battery so the two pack was perfect. They both fit and work perfectly!

  18. april kelley

    Only charged it once and still going

  19. Michael W Cooper

    using as power wheels replacements. Easy to swap in, work just as well as the stock batteries.

  20. Chris

    Shipping was fast. I was able to change it out and charge it right away. It’s been run for several hours before needing a charge.

  21. Mike R.

    The battery fit perfectly in my Black & Decker hand held spotlight and brought it back to full brightness. I cannot speak to how long it will last. Seems to charge fine though. No problems.

  22. Jim in California

    This battery got it running again, and you can’t make Margaritas on the patio without a blender.

  23. SteveA

    Fits perfectly. Exact size of one that came out of the spotlight/lantern. Works so far.

  24. BP36.

    Batteries arrived promptly and were properly packaged. All of the batteries were charged and all had the proper voltage. The batteries are working well.

  25. Lena Kong

    This battery is still juicing up the old Sunbeam bug zapper. Bye bye mosquitos, yowsa.

  26. Web Customer

    Used this battery to replace the original one that no longer worked. Was able to get the granddaughters driving machine up and running again with this replacement. Too soon to tell how long it will last between charges and what its overall life span will be.

  27. Tammy lujan

    Perfect

    So far so good we will see life of this product later

  35. Destiny

    We have a dynacraft unicorn-original battery went bad within a year of having it we purchased this battery and so far it’s been awesome. The company wanted to charge 40$ for a replacement battery so this is great for the price

  36. mel

    works great for exercise eqipt

  37. Troy Huckendubler

    Worked great in my daughters powerwheel

  38. Daddy Fix

    Nothing to dislike. Made in Thailand, not China. It fit our Coleman air mattress inflator perfectly. It came already charged. Not quite sure why, but this one did not show up near the top of the search results, even though it was well priced and was available next day prime. I’m glad I took more time to look.

  39. Daniel

    Seems to work just fine and a good price.

  40. Bobka

    I bought this battery to repair a rechargeable flashlight. This item was a perfect fit and the seller was very good.

    This was a replacement for my Grandson’s power wheels, very happy with this battery

  50. Dryan Cole

    Works better than OG

  51. Chelsey

    Works great for my sons bumper car. It needed a new battery after sitting unused for a year. Easy to put it.

  52. Jerry Y.

    I bought this battery 60 days ago and wanted to wait this long before doing a review. It has been working great in my hand held vacuum. It takes a recharge and keeps the vacuum ready to be used again. it also lasts a long time in the vacuum before needing to be recharged. Very pleased and the price paid is reasonable. Usually I get about 4 years with one of these batteries in this vacuum before needing a new battery. I expect this one to last that long also.

  53. Donna Dey

    This battery is awesome. Super cheap and I’ve never had to charge it even straight out of the box. Much better than paying $30 for the power wheels battery

  54. LoriEleanor

    Great price, fast shipping

  55. Joshua A.

    Not sure how long their life span will be. The charged and work like the original one did. With two, they double the ride time for my kids.

    If anyone still owns an RCL-3000 lantern this battery fits perfectly! Since I recently purchased this battery longevity and battery life is unknown but sure it will last for years if properly charged periodicaly.

  62. ryan

    My kid loves his 6v Costco paw patrol cruiser. I have the holes and scratches in my walls and baseboards to prove it. The cheap Chinese batteries in them last for about three months. This battery is the perfect replacement and charges great with the original charger and lasts 4x longer.

  65. Web Customer

    Just the type of battery I was looking for at a great price.

  66. Web Customer

    Replaced a fisher price power wheel battery with this generic replacement. Same battery spec as the oem model. I had to crimp standard wiring ends to the power wheel to mate withthese standard battery terminals.

  67. Peter Calabrese

    Have not had long enough to judge fully but all six came and work as advertised. My one complaint is that I wanted to order the 6 pack for the good rate but the shipping of the six pack was advertised as at least 2 weeks delivery time. I needed them ASAP so I ordered six individually. They came quickly in six separate boxes, but all of them neatly fit in one box. I can;t believe it was actually more economical to make 6 separate shipments. If they last I will order ahead of time but disappointed in this aspect.

  68. Storm

    Kid has a battery powered dinosaur and loves riding it. New battery ass days of driving around

  69. Web Customer

    Used to replace battery for a princess power wheel that used same type of battery. Although it worked it didn’t have enough power.

  72. John Guagliardo

    Replaced battery in old rechargable hand-held spotlight

  73. Plakan

    Value for money

  74. jds

    I purchased new headlight, signals and taillights. Front was a bit tricky and tail lights were very easy. I am sure that my lights will be much brighter than the old ones. Also my 11 year old truck looks much better. Very happy so far.

  75. Dan

    Works great and perfect replacement.

  76. Dan

    Works great and perfect replacement.

  77. Robert Davis

    I don’t know how long they will last just put them in.

  78. JH

    Needed a 6v rechargeable battery to replace in a hand tool that an oem replacement was not available. required some creativity in order to mate the battery to the tool, but the compact size of this battery allowed for an easy solution. After making sure this new battery was fully charged before first trying it out, I was surprised to find that the power, and duration of the charge far exceeded what was originally installed on this particular cordless garden tool . Considering the price-point,, this purchase saved me a much costlier experience if I would have simply replaced the entire tool……….This has breathed new life into a tool I have relied on for years.

  79. Sagun

    It is wrong product I need to return or money back for this product. asap thanks.

  80. Nic

    Great replacement for my son’s battery powered quad rider!

  89. Elizabeth Wiggins

    When a tropical storm system was threatening us, we starting preparing and discovered a bad battery in our lantern. We in-turn ordered an affordable new battery and received in 2 days before the storm hit.

  90. Everett Couch

    fit properly

  91. kern

    Brought back life to a Lightening McQueen ride on car that we almost trashed because we thought it malfunctioned. Simply need this new battery that worked straight out the box. Had to cut the two wires from the old battery connection then wire it to and through the pins of this new battery making sure to tape them securely with electric tape. Kids have used it and recharged multiple times and I’m very happy with the purchase.

  92. John Caddell

    Awesome.

  93. S. Thomas

    Bought to put in an air mattress inflator instead of buying a whole new pump. Saved a bunch of money and works just fine!

    Good so far. Replaced the have-been-dead-for-ten-years batteries in two (completely different brand) handheld spotlights and these worked great. I think the original batteries were more like 2 or 2.5 AH so these have been an improvement.

    Fits and works perfectly in my crank-up spotlight. Good competitive pricing, and fast deliviery are always a plus for me. Would buy again from this supplier.

  154. Blue Crab

    I saved tons of money when i bought these! I use them in hunting camp for feeders and have used them also for trail cams. They work great and hold the charge well. The biggest thing is the COST! I saved about 560 to 60% over a BIG BOX STORE. Well worth it! I don’t give good reviews unless i mean it!

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
