LiFePO4 Lithium Car Battery, 12V 90AH 1300CCA Group 49 Starting-Stop Battery, Built-in Smart BMS, Perfect for Automotive Car, 60 Months 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.

This is half the price of the other popular one, but it works great, has a voltage read out with current volts, and also shows battery percentage. I have it in my 2022 Hyundai Ioniq 5, it's way now stable than the factory stock battery. I needed a stable 12v source for my aftermarket audio system with 5ch amp pushing almost 800w rms in total.

Perfect fit in my 2016 Toyota Tacoma TRD Sport. Less than half the weight of my previous battery and feels like way more cranking power.

Picked this up for my Fiesta ST and holy cow it's so much better then a standard battery and it's lighter by a lot. Time will tell how it holds up here in Phoenix.

Claimed to be a drop in size group 47. Bottom of the case was too big in order to be clamped into the battery tray of my Kia EV6.

This battery was the perfect fit to replace the AGM in my 22 Hyundai kona N. The cranking power its got is insane, it's about 1/3 the weight of the AGM, easy to install. The seller was incredibly good with communication. They reached out to me after I ordered to verify that I needed that specific battery type, took pictures of the actual product and gave me exact dimensions so I can verify and confirm. They were great.

Awesome product and the shipping was the fastest. I have ever seen.I got it the next day!!!!

My battery was DOA. The instructions included are basically worthless (it's 1/2 of one side of an 8x11 sheet of paper, mostly warnings), but it does say "empty battery can be used after charging for 2 hours..." So I bought a lithium-capable charger and tried it. Nothing. I looked up reviews and found out that the little display should come on when you touch it if it has any charge at all, and it usually comes with 80-90% charge. So I thought it was defective and set up a return, but then I tried the charger on my old battery and found out it didn't work at all. So I got a new charger and was able to charge this battery. Apparently it had arrived with absolutely zero charge, not even enough to power the little voltage display. It was at 16% after the two hours of charging listed in the instructions, but only showed 8.6 volts, so I wasn't confident it would work if I installed it then and let it charge overnight. It took 26 hours to get it up to 88%, at which point I installed it and it works.The product listing has ten times more info on it than the "instructions" do, even though a lot of the listing is in broken English, that's how bad the instructions are. Between that and arriving so completely uncharged I thought it was defective, I can't give this five or even four stars.
