Weize Lithium YTX20L-BS, Group 20, 600A LiFePO4 Motorcycle Battery, 12V 8AH ATV, UTV, Jet Ski, 4 Wheeler, Snowmobile, Personal Watercraft, Seadoo, Polaris, Generator and Riding Lawn Mower Battery

Purchased for our 2013 HD RoadKing. The old Harley battery was starting to show its age and required frequent time on the trickle charger. Also had a lag when hitting the starter even though it never failed to start the motor. The old battery had about 375cca and The new one has 700cca and there is a big difference when you hit the starter. Now, it cranks that baby right away with no hesitation. This battery also weights at least 20lbs. less than the lead acid battery it had, therefore it’s way easier to remove if you need it to. The battery showed 13.5 volts right out of the box. It came extremely well and meticulously packaged. You can see the great quality of the terminals and the new hardware provided. The size was a perfect fit on the RoadKing and the terminals perfectly placed for a great connection and this made it an easy to do so. This was a great value when you compare it to others like product if you can even find one as impressive. Just a word of caution. You will need the proper charger that can handle the Lithium battery. A standard charger will not work on these so you will have that extra expense if you don’t already have one as I did. The durability is still an unknown but having used similar lithium cell batteries, it’s very unlikely that they will fail. When they’re bad, you will know right away. Just my personal experience with these. If this battery durability or performance fails? I will be on here immediately to report any issues, I assure you. In closing, I highly recommend this battery.

This is one of the best motorcycle batteries I have bought for my Harley-Davidson Electraglide Classic. It's super high cranking amps are perfect for that big 96 cubic inch motor, plus it's compact size and light weight show state of the art technology and engineering. Great performance!

I have a 2007 Suzuki m109r, This is an 1800 cc V-Twin engine and it requires quite a battery to turn it over.... The last battery I had in this motorcycle was a shorai lithium battery, and it would literally crank this big engine like a capacitor discharge.... After about 4 years and probably because the bike had been sitting for so long and not being charged regularly finally failed so I installed a brand new mighty Max lead acid agm battery rated at 230 cold cranking amps .... The battery worked fine for initial startup while the engine was cold, but once I ran the bike and got the engine hot I had to hit the button three times to get the engine to rock over to start.... So I ordered this battery which claims 500 cold cranking amps ... It fit perfectly in my Suzuki M109R... And initially it seemed to crank the engine over well, But then back to the labored cranking... When my bike is running it shows about 14.2 volts charge rate and when the bike is sitting after a week or two it shows about 13.4 before starting... When I hit the start button the voltage drops way down and yes my cables are tight and there are no accessories drawing off the battery when the bike is off... It shows the weight of this battery to be over 3 lb but as you can see in one of the pictures it's only about 1.6 lb... Who knows maybe I just got a bad one and if you were cranking anything but a big b-twin I'm sure it would probably do the job... This particular battery that I got is nowhere near 500 CCA I would guess it's closer to about 180

I ordered this to put in a Kawasaki ATV. It was listed as a direct replacement for a YTX14-BS Battery. Nothing could be further from the truth. When it arrived I knew it would be lighter, but it felt almost empty. I decided to read the manual before doing anything. Right on the cover over the Manual it Said Starting Battery. I thought that was strange , then I started reading more.. It became apparent that this was a battery only for briefly starting the vehicle and nothing else. when I read the warnings it basically said do not connect any electronics without authorization or damage will result. I have uploaded the manual pages here. I messaged the manufacturer to tell them I had a winch, stereo and light bar on my ATV. Here is the response I got "The Weize Lithium YTX14-BS battery can provide sufficient power for basic ATV functions. However, accessories such as winches, stereo systems, and large light bars typically require more power and may cause a sudden high load on the battery. Therefore, this battery may not suitable for safely powering all these accessories. You should consider a higher capacity battery that is designed to support high-power accessories to ensure safety." So, after getting that message and reading the specs break down which is also here in my review. I returned the battery. After reading the detailed specs I have a guess as to what this so called battery actually is. I believe they have some small number of 18650 Lithium cells or some other model#. Then they have two or maybe more capacitors in there. When you start your motor you get a 3 second 500cca burst from the capacitors which then turns into 200cca for 10 seconds according to the manual. And that is about it. then while you ride it will recharge the Lithium batteries which will charge the capacitors. At best this is a Hybrid battery that as the manual says right on the cover is a starting battery. It really cannot do anything more. I cannot imagine having this battery in a very cold climate where you may encounter hard starting. This battery would be useless I buy lots of AGM batteries from Weize that are always a good performer as well as a good price. This is not one of those batteries.

The Weize Lithium YTX9, 400A LiFePO4 Motorcycle Battery is a solid upgrade from a standard lead-acid battery. It’s lightweight, holds a charge well, and provides plenty of starting power. Installation was quick and easy. The only reason I didn’t give it 5 stars is the price—it’s a bit higher than traditional options. Still, the performance and long life make it worth it.

I thought my Harley battery was ok, maybe a little older and weaker than new but ok. Got some grinding when trying to start it a couple times so I was concerned that I might need a new starter. It usually started ok and ran fine but one day after riding to the DMV when I came out the motor turned over slow, made the grinding, continued turning slow and then fired up! Went straight home and parked it and put it on the charger. It showed charged fairly quick so that's when I started wondering about the starter. Long story short, I had started to suspect the battery and one day after putting it on the charger when I came back to check on it the "Trouble" light was on. Researched some batteries that day and ordered this one and now it turns over the motor easily, haven't had an grinding at all and it fires it up so fast it actually startled me the 1st time! Ordered the lithium iron charger with it and charged it up before putting it in the bike. Install was easier due to the threaded posts (with provided bolts)-another reason I ordered this over others as it was enough of a pain to install because of the short pos/neg cables without having to fight with holding the battery AND a tiny nut while trying to thread in the bolt! Finally, the 5 year warranty is a plus in offering some piece of mind that I hopefully won't need to worry about it for quite some time but if I do, being a name brand, they will take care of it. Very grateful this seems to have taken care of my problem and I don't need a new starter! 5 Stars

WOW!! I installed this battery in my 2014 Harley Davidson Ultra Limited. Since the bike was new, it has always taken a strong battery to start up. I have been through many batteries that weren't Harley batteries trying to find a cheaper option since you have to pay an extra $100 just for the HD name on the battery. None have worked longer than a month until I bought this little dandy. My bike has never started this easily since it was new. The 700 CCA is just what it needed. I can't say enough how great this battery is. Last year I put a Weize deep cycle marine battery in my boat and I am sold on the Weize brand batteries. I will only use this brand for all my boats jet skis, motorcycles, trucks and cars from now on. Best batteries I have ever had! Strong, powerful and ready to go right out of the box. I am amazed at how cheap they are priced for what you get. Do yourself a favor. Buy this battery and you will see what I mean and no, I am not a representative of Weize. I am just an old retired dude from Oklahoma who appreciates quality at a great price!!

This battery was a perfect fit in a 2011 Harley Road King, from overall size to post postition. Bike was cranking slowly with the 4 year old, 380CCA lead acid battery. This lithium battery is amazingly light, I picked up the UPS box and I was concerned there was no battery in it. Fit perfectly in the bike, and let me say, I've had quite a few Harleys with 98 and 103cc motors, they all seem to crank somewhat slowly especially on that first rotation. This battery has the motor JUMPING to life on the first rotation, I've never had a Harley start this quickly or effortlessly. I also hooked up to my battery tender, the tender showed it was charging for a while, when I checked later the green light was on indicating it detected a full battery. so the lithium battery management system seems to play nicely with the standard battery tender. Time will tell on longevity, but first impressions are that this is a light, powerful battery. Copper threaded battery posts are a nice touch, compared to the game of skill and change you usually have to play with the lead posts on most batteries and the little square nuts that you have to get in place and pray they don't fall out into the abyss under the battery box.
