Okay, I lied. Here we are a year later, and the batteries are still kicking hard. However, I cracked the frame on the chair, and had to get a "new to me" chair. My family and I recently became homeless, and the chair took an absolute beating trying to move furniture, and trying to handle a young Husky with a propensity to run off... through the woods... The batteries never missed a beat. So, when I was able to get the new chair, since it was donated, they warned me the batteries might not last very long. Unfortunately, this was more the case than I had hoped. My Ex stepped up, and provided the funds to get new ones, so I came back to NERMAK. Here's where things got weird. I purchased 2) 36AH batteries and my payment was declined, order cancelled... 3 times... Then I tried switching to another account. No joy. Something weird was going on with Telecheck. In desperation, I reached out to Customer service and the company directly. A few messages, clarifying some things, and they fixed the problem, and I got my batteries. I am officially a customer for life. If these hold up anywhere near as good as the others, they will probably outlast me. ** Final Update** Maybe... The last couple days have been intense, and even though I beat the absolute snot out of these batteries, they never missed a beat. Yesterday saw 8 miles around the neighborhood, and only one lost bar. **remember though, it isn't completely accurate** Rescued some ducklings, went to the store a few times, etc... Today however, I hooked up my old bike trailer to the chair and went full grocery shopping. Now even though this was 10 miles round trip, I'm hauling a trailer with a few steep grades along the way. Got to the store, I'd lost a bar, I expected it, so I plugged it in while I shopped using the handy "mart cart" Full load minus trailer was close to 80 pounds (36Kg) With the trailer, and me on board, it was about 260 lbs (118Kg) The full capacity of the chair with 18AH batteries is 300 lbs (140Kg) Remember, these are 12AH. That short 1 hour charge got me all the way to the gas station near my house, where I had to stop anyway. I put it on charge for 5 minutes, and hobbled in to get what I needed and made it home no issues. NEVER, even with my old chair, that had 35AH batteries compares to these. I'm not saying they'll last longer, but they are significantly lighter, and apparently far more power dense. I want to see what a 100AH ones on my trailer will do. Add a solar panel, Unlimited range...lol. Oh, Yeah, that's a cooler on the back, too. 7 months in... My old batteries would need replacing by now. These just took me on a 5 mile round trip over on a rough shoulder with a steep hill. Even though these are lower capacity compared to the old lead acid, they more than make up for it in weight savings. Essentially making it easier for the batteries to move the chair. I have a set of smaller ones in my cart for a RC lawnmower project I'm working on. Compared to the old batteries, I wish I could give these 10 stars. **original Review** A few weeks in, and 5 stars isn't enough. Everything I say below, and more. I've only charged these things a few times now, whereas with the SLA, I'd have to worry about topping off, or doing a maintenance cycle, which only seemed to kill them faster. These just perform. My range has increased significantly, but I don't have actual measurements. I reflexively look at my battery gauge, but I'm always surprised that I still have charge. I think the primary reason for the range increase is weight. These things feel like air compared to my old batteries. please read my original review below*** ***I bought these to replace the batteries in my Pride G0-Chair. I've been through 3 sets of the "Recommended SLA" batteries from the manufacturer, in three years. I don't use my chair every day, but when I do, I'm usually pretty hard on it. That said, the last set, which I bought from Interstate battery directly, only lasted mere 8 months. I was down to about .3 of a mile before charging, when the specifications list 8+ miles per charge. Though these come out to only 2/3 the original capacity, (12Ah vs. 18Ah) I was able to travel over 5 miles over 4 days on a single charge. I wanted to test the built in BMS's, and I also decided to order a charger specific to 24V, so I didn't charge it. The BMS safety kicked in and shut down my chair at my neighbors house. THIS IS NOT A NEGATIIVE!!!!! Regular SLA or AGM will let you discharge them to death.... literally. The protection worked as hoped, and as a bonus, I confirmed that the battery gauge is "close enough" to read these. If it starts blinking red on the controller, get to an outlet, or get home quick. The BMS doesn't play. I will say, they hold the green far longer, and once your into the yellow, they do fall off faster than I expected, but that is the nature of Lithium vs. lead acid. These do not fit my battery box , but I knew that going in. However, I am going to modify the box, and given the space, I will be able to install the charger on board. Which brings me to my final point. These things are LIGHT. I mean feather weight in comparison to the SLA/AGM batteries they replaced. Even if they matched in size and capacity, I can't imagine them weighing much more. They are literally about 1/4 the weight. The entire battery box weighs less now, than just one of the old batteries by itself. ****NOTE**** I had to change the terminal connections and am making modifications to my chair to accommodate these batteries, and have a good understanding of electronics, and electrical and charging systems. I used to build defibrillator's for the medical industry. Do this at your own risk!!! Even though it says you can use an SLA charger, I recommend a 29.2 volt charger specifically for LifePo4 batteries, if you are on a 24v system like I am. Last word: These are light, powerful, and charge relatively quickly at the recommended 5 Amps. Because they are so light, I plan to build a second "backup" for extended range. Even 4 of these only weigh as much as one of my old batteries. If anything changes, I will update. **Update** Okay, still 5 stars. Wish I could give 6. On my second charge cycle, and even more impressed. I don't know about longevity yet, but given my initial experience, and if they last even close to the specified number of charge cycles, these batteries will actually outlive me.

I used them pretty harshly on a scooter with my daughter and I we use it every day 1 to 2 miles. The original set up was with lead acid so I have to charge them individually, but it’s still worth it. The power difference is quite significant some of the lead acid batteries you order on Amazon have been sitting for over a year, plus lithium batteries hold out a lot longer during storage and if balanced and charged properly will perform better during use, I fully recommend this product.

These batteries stayed charged and are so much lighter. Very pleased w my upgrade. Makes using the mobility scooter a much better experience. Particularly helpful because I transported the scooter in my tiny fiat and the battery weight getting it in and out of the car made a big difference!

In my 62 years. this is my first review. Now. About. this battery. when I first got it. I I would had Given. them a 5 star but Through the 90 days that I had it. I was getting less and less distance off the. charge. To where it wasn't worth charging. anymore. With the batteries I also. bought. a 24 Volt 5 amp lithium life PO4 charger So I was using the right charger for the batteries. Lithium. batteries. Here's the fun part. I try locating the company. on on any and every type thought I could come up with the locate the company. And of course, I know they're in China. Tell no reveal Gotta hold of Amazon. They gave me a 14 or 16 number. to call China. I had no luck. Got back with Amazon. and explain to them how they had this wonderful guarantee on the batteries 5 years or 2000 recharge in 90 days, maybe 15 Charges. my bad forgot to tell you what I was using it for. My mobility scooter. It took two batteries to operate it. Amazon told me again. There was nothing they could do about the warranty that I had to get ahold of the company. And you know how that went. But I was consistent with Amazon. and ended up with less than half of my money that I spent for it. In reality, could have been nothing so again, I guess thanks for Amazon. So I hope you learned something from my text. Like I said, first time I left the text for you all to learn From this. What I did learn from this is I'm going to American company. and pay a little more. for the support with that. Thanks for reading my text.

Worked perfectly for my scooter! Also had a mishap with using the wrong charger and sent too much current to my battery. The protection put in place in these batteries prevented them from being fried. Will definitely purchase again when I need new batteries for my scooter.

I have waited for almost a year to review these batteries because batteries can only be genuinely reviewed once they have been used, charged, and tested at length. These batteries were purchased to replace batteries in a Drive Medical Scout 3-wheel scooter. The scooter batteries are housed within a removable, waterproof case that can be removed from the scooter and recharged. In particular, with medical equipment, you want a product that works — work safely, and works the first time. When receiving the batteries, they appeared new and did not have any cracks, damage or wear visible to the casing or attachments. These batteries were lightweight in comparison to the batteries that came with the scooter (a bonus). They power the scooter without issue and recharged fully, reliably. They fit within the case comfortably as a slightly smaller, lighter weight product to the batteries supplied by the DME. There have been no noticeable issues with the performance of these batteries regarding holding or maintaining a charge, or losing charge early, and they have easily powered the scooter. From this specific vendor and this model, these seem safe to use to power your scooters and similar equipment.
