I got the box and thought I had been scammed. Easily 1/10 the weight of a lead acid battery. I wish the terminals were a little more standard, but being threaded and solid vs wrestling with that dang small nut that typically goes inside I'll take this one any day! Can't say how it works yet, but it was at 95% on my charger when I plugged it in. I have a quad that's been sitting for a several months that will go back into plow duty and heavy use on the winch. It will be good to see how it works.

I needed a new battery for my generator starter. This one fits perfect and has higher cca. I have started the generator around once a month since putting it in, ready for winter storm season. I keep the generators batter charger plugged in through the whole winter to make sure it's topped off when the time to use is is needed. This is less than an appropriate small equipment battery at the local nationwide chain store. Good deal in my opinion. It also appears to fit my riding mower if needed.

Reading the specs of this battery, I was impressed. However, I never used a sodium-ion battery in any of my machines before, so I was a little skeptical. I'm pretty happy to report, this battery from Acoucou work very well! My concerns have moved on. I am getting strong starts on my rancher ATV. The specs and capacity of this battery are solid for most motorcycle, ATV, and similar vehicles. It provides 250 cold cranking amps. So that covers a good bit of 12v needing machines. It also has a very high rating for battery life, per the listing. Time will tell, but it is again impressive. I couldn't believe how light this battery is when I unboxed it. It weights probably less than half the lead based battery I removed. It also was a little concerning because I expected it to be empty inside when I felt how light it was! Unfortunately I was not successful in installing this in 2 of my machines. My Yamaha quads both couldn't fit this battery. It was just about 1/4 inch too big to fit into the side can of the Big Bear. It was also too big for my Wolverine quad under the seat box. But finally, I tried it in my Rancher 400 and it fit nicely. It also is starting that ATV very well. Strong and consistent. So despite the compatibility issues, I am happy with this battery. It's a little on the high end of the price range for my ATV batteries. However, if it last as long as the listing claims, it may well be worth the extra. For now, all in all, I give it 4 stars.

Less than a month update: battery is dead. And when I say dead, like overnight non-responsive. Also, battery charger does not recognize the type of battery and therefore does not charge it. As stated before, worked like a champ until it didn’t. Going back to lead acid until the bugs are worked out. Sending it back. Battery is super responsive. Charges and discharges like a champ! It is super light weight when compared to lead acid batteries. Cost less than a lead acid battery. Fitment was a tad off, as the copper connection blocks were slightly too big, but bent the tab on the connector and bam, works like a champ!

I installed this sodium ion battery in my 2012 Harley Wide Glide and it cranks the big twin over easily even from a cold start. The power delivery is strong and consistent every time I hit the starter. It’s nice knowing I don’t have to worry about the cold garage temps affecting it since sodium batteries handle freezing weather far better than lithium or lead acid types. The battery came fully charged and ready to install. I always keep my bikes on a tender when stored and this one holds voltage very well between rides. It’s lightweight, maintenance free, and gives quick starts without hesitation. Fit is perfect in the stock battery tray. It drops right in without any adjustments and the terminals line up exactly as they should. For the performance and reliability this gives, the price makes it an excellent value and a smart upgrade over traditional batteries. I’m so impressed with it that I plan to get another one for my snowmobile since this type of battery really shines in cold weather.

The lead-acid battery on my mower goes bad probably every two years, due to the massive neglect I show the thing. So, I needed a new battery, and this one was available. I tried it out. It works! It's amazing that a battery a tenth of the weight of the lead-acid original can actually crank and run my mower, but it's true. Otherwise, it's been a drop-in replacement and you'd never know the battery is using different chemistry unless you flipped up and seat and looked. Only very very minor issue is that the case size is a little smaller than the battery that should be in there, so I had to jam a stick under the rubber hold-down strap to keep it from banging around. Not an issue with the battery so much as an oversight on my part when ordering.
