Lithium Car Battery Start and Stop, 12.8V 576WH Group 47 LiFePO4 Automotive Battery For Car, Starter Battery, 36 Months Warranty

I put this group 24 in my Lexus LS400, it fit perfectly, the cranking speed is outstanding, the alternator charging 14.2 volts, amps initially was 30 amps from alternator, settled down to a little under 10 amps once the BMS learned the alternator output, after researching the high amp output from charging system. No problems at all with this last arctic blast. IF** you have a no start cold, turn on headlights high beams for 5 or so minutes THEN attempt cranking. It's counter intuitive to do that as we are used to LA batteries, lithium must warm up to get to robust large amp discharge. Current flow will warm the batteries.

Initial Review: 2004 Subaru STi (group 26). Received battery yesterday at 87% charge, about 13.3V. My alternator runs about 13.8-14.0 at startup. I charged it for about half an hour while I tried to decipher the weird instructions that came with it. Ultimately just decided to swap the battery in a usual fashion. By then it was at 93% according to its own diagnostics, around 13.4V. Fits directly in without any modifications. It is feather light. Hooked it up. Car cranks a little faster than my tired lead acid battery, which was struggling to maintain 12V. Car started fine. Idles normally around 13.8V. The battery shows 100% at this point. Will have to see how this plays out over time. I drive this car rarely. Also the tires dictate no subfreezing temperatures. I have a battery tender that is capable of LiFePO4 chemistry, but I frequently forget to hook it up, so I'm hard on batteries. My garage is insulated but not climate controlled. So far I'm happy, and if this holds up, I'd never buy another lead acid battery. The weight savings are like getting 1-2 free horsepower, and it's taken from the front of the car. One more tip: get a 12V lighter USB adapter with a digital voltmeter. For like $10 I now have accurate voltmeter that matches my multimeter and has a USB-C outlet as a bonus.

Dont waste your money. Worked well for a couple of weeks, then wouldn't hold a charge, then the bottom of the battery case melted. Seller wont respond to inquiries regarding the 60 month warranty.

Almost a drop in replacement for the dead H5 that was in my 2013 smart fortwo passion cabrio, and is working great after two weeks. So much lighter too - easier to put into the vehicle because it is so light. Exact fit - except it is not a true H5 battery because it does not have the two holes in the handle for the positive terminal cover. I drilled two holes for the cover and all is well. That said, the picture shows the holes and the battery I received did not have them. I believe that the items received should always match the pictures for the item being advertised. Oh - made in China if that matters to anyone. The stock charging system is operating perfectly with this battery - I have a Bluetooth battery monitor attached to the battery and nothing is not where it should be. Starting voltage is higher with this battery than stock, and it appears that the headlights do not show electrical load changes like the flooded battery did - I think the LiFePO4 responds quicker to load changes than the stock batteries. If any of this changes, I will update the review.

Perfect fit in 22 ioniq 5 original battery had dead cells in cold weather. No issues since replacing the original with this one. Nice to be able to easily check the battery with the push of a button while adding washer fluid.

Great battery and extremely light weight. Have 2 in my ratrod to keep up with my dual radiator fans and rooftop AC.

It's been 4 months now and no issues, other than being under the impression it was a direct replacement battery for my 22 Kona N. To be fair, trying to find the exact group for my car wasn't conclusive. I only bought this battery for my curiosity. Since I was having issues with a powertex battery more than double the cost of this battery, I thought I'd try it out knowing a little about batteries. Anti gravity and powertex are seriously over priced. Using my automotive electronics back ground. I was able to use the stock battery wires after removing them from their holders. See images.

I bought for my daughters 2008 VW Beetle and thought that new tech meant better! The battery build quality appeared very good and light weight. It installed easily but after driving it for a week, the car stared to have issues. The radio would turn off and restart randomly while driving and I did notice a hiccup in the car while driving. The alternator light would come on for a couple seconds and would disappear at the same time the radio comes back on. I do notice the headlights look dim while driving at night as well. The alternator is less than a year old and should have no issues. I do notice that before the battery swap, I was charging voltage was at 14.4V while on. With this new battery, the voltage charge dropped down to 13.4V while driving. After trouble shooting this with my mechanic, it came down to this battery issue. I had to replace this with the standard AGM and now the car works fine with bright headlights. It is charging back to 14.4V. I ended up return the battery. Not sure how everyone else is doing fine with theirs but my car did not like it or the battery was defective out of the box.

Awesome packaging, great product and my god is this thing light!! It’s great as my 2nd battery as the after market holder isn’t the sturdiest I find. It would probably make a great battery on its own, but I needed the extra juice when I plow. So this will be perfect!
