GROUP49 12V 90AH Car Battery High-Performance Lithium Start-Stop Battery with 1300 CCA and 60 Month Warranty

This is the most impressive battery I ever purchased for any car. When I took out the old one, it weigh about 40 lbs to replace it with this one and it’s 16 lbs, I was stunned. It is smaller with more power, never ever needing maintenance. The car started very well. The battery even has a display showing voltage, and charge status in %. It does not discharge over time. Ergo, when I store the car over winter or longer periods, no charging, no cables dangling, etc. Can highly recommend this battery!!!

I tested this battery by hooking it up in parallel with an existing 12Ah battery as the primary storage in my device-charging solar setup. See attached pix. It took about two hours to charge to full, drawing a maximum of about 4 amps initially, and tapering down. Everything stayed cool. No fuses in the charging lines blew. I then tested its ability to run my 12 volt input charging system and it worked fine.I don't have a good way to measure its claimed capacity. It's about 60% of the volume of the 12 Ah battery sitting to its right in my second photo. I'm going to believe the vendor's claim.It's supposed to be good for 2000 charges cycles which is great. That makes it about three times lighter and able to take four times as many charges as a comparable GEL battery. I'll take that.

Arrived in a heavy box, but only had very thin foam about the battery. The terminals were insulated and nicely printed branded labels were applied. Good fit and finish on the battery case. No manual or data sheet was included. Certainly an odd spec at 7.2Ah, but time will tell. I'll have to use it a bit to see how it performs of course, but for now it looks promising.

Battery works great. It’s very lightweight and well made. Sturdy, and the terminals look to be of good quality.

I've reviewed a ton of LifePO4 batteries and this has the best finish of all I've seen. Not saying that makes it wonderful, just something I noticed. It is well made for a battery, all sealed up nicely and ready to use. It measures just over 13 volts out of the box. Has standard spade terminals for easy connections. Looks good so far.Couple thoughts, this is a very odd capacity. Never seen any battery with .2 some times .5, but never .2. Just strange. Also, this seems a little pricey for the size. But that is only my opinion. Also, some contradictions, on the battery is says super long lasting at 2500 cycles (actually that that is not exactly super, many LifePO4 batteries do more cycles), and then on the product page it says 4000 cycles. Which is it? Just a concern with different information.Good battery, if you are okay with the price would recommend.

This is really small and portable. Worked great running some radios.
