I do pest control. I bought a Vevor 4 Gallon back pack. And after a few months the battery would not charge. I really like the back pack and I wanted to keep using it. I looked up the model number of the battery, and I ran across Mighty Max Battery. Same specs and everything. The price was right and I purchased it. I put it in my backpack, and now I am back in business! I just got it today, but I usually charge my battery every 2 weeks. I know without a shadow of doubt that this battery will do a mighty good job!! Read more
When this battery arrived, it was fully charged. I confirm that using my trickle charger. Works great for my fishfinder. Read more
Work fine for alarm system backup, security camera backup, and garage door opener backup. I use them for five years and then replace them. I then use the old ones to run kid's electric cars, bench power supplies, and ham radio power. If you clip a coupla LEDs and resistors onto one it will run for a weeks worth of power outages all night. One will easily run your fishfinder all day w/o hooking the ff'r up to electronic noisey engine or trolling motors. These particular ones are doing alarm, sec-cam, and door opener backup. I test them when I replace them on the bench first. Charge 'em, run them with a 200mA-1 amp load for a few hours, charge them again, let 'em sit overnight and measure their voltage the next day. These passed my tiny tests and are now installed. Read more
Was a good battery, just right for my needs in powering an oxalic vaporizer for beekeeping. However I only ever used it once really before it broke. I used it once to treat my bee's, then charged it and stored it at room temperature inside a heated garage (no moisture), with periodic recharging about every 1-2 months. Just took it out to prepare to treat my bees before spring hits. Figured maybe the battery was low since it had been about a month since it was last charged, hooked it up to my battery charger and got hit with the code for an internal short. As a plus though, despite this internal short the battery never leaked, got hot, or had any corrosion on it, so the external casing is at least well made. I'm going to attempt to reach out to support about this, and see if I can get a replacement as I can only assume this is a manufacturing issue, or I'm just really unlucky. Update: Reached out to customer support on their website about this. Got a tested replacement sent to me without much issue. Very good customer service, and they were quite quick about responding. Cost me nothing for the replacement, they even payed for shipping. Overall, a very pleasant experience compared to other times I've dealt with customer support services. Read more

Great price, I purchased two of these batteries for our lift master swing gate operator. After rebuilding all electronics on it and installing these batteries we're back in operation. Very pleased with our purchase, just what the doctor ordered. Read more
Worked as expected. Received the order quickly. I use the battery on my Muddy game cameras Read more
As a business, I will not do business with this company again. The 2 batteries I ordered were received but after install into my UPC device they would not take a full charge (50%) and then failed completely within 5 days. Sometimes stored batteries fail - I was okay to this point, but the return process ate up another hour between first being directed to the Mighty Max website from the Amazon return process where I provided my order info, then getting a reply from Mighty Max a day later that they needed a copy of the invoice, then providing the invoice and getting a reply from Mighty Max that I had to contact Amazon, then 30 minutes on the phone with Amazon getting a refund processed. A bigger pain-in-the-you-know-what than it should be after already being inconvenienced. Read more
