    • UPDATE*******So far I'm impressed. Very impressed. ****See Note****
Size: 12V 12Ah-2PACK
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. ... show more

    • Perfect for our solar gate operator
Size: 12V 12Ah-2PACK
We used these two batteries wired in series for a 24v 12ah power source for our solar gate operator. They charge all day and if you’re not opening and closing your gate 10x a day, these hold the charge. 2 weeks in and no issues. These tiny batteries are great and I’m so glad I went with this easy to install package vs any bigger SLA batteries. Great option for the price. ... show more

    • A good choice for camping or for trolling motor use
Size: 12V 75Ah
I use this to power a trolling motor for an Intex inflatable. I took it out only once on the water and it lasted over an hour before the battery started to show signs of discharge. I also use it as a backup power source in conjunction with a 750 watt DC to AC power inverter which I use to run an electric blanket in my tent. One thing I would like to mention is that if you have a charger that's 10 amps or less it will take quite some time to recharge this battery so you may want to upgrade to a 15 or 20 amp charger if you want to be able to recharge this battery within say 3 hours or less you need a decent amount of amperage on the charger. I highly recommend this battery. ... show more

    • Failed in less than 2 months (revised)
Size: 12V 7Ah
I bought this for my daughter's jeep and it failed in less than 2 months, so like 12 to 15 uses. UPDATE: revised from 1 star to 4 stars, seller reached out and offered a refund. Although the battery failed, the response was quick and they recommended an alternative that should work better.

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. ... show more

    • Outperforms lead-acid gell cells.
Size: 12V 7Ah-2PACK
These batteries directly replaced the old gel cells in my UPS. As a direct replacement they are designed to accept the (lead acid) charging parameters of the UPS and can be discharged further than the lead acid gell cells. No issues, and a no brainer!
