Weize Lithium YTX14-BS, Group 14, 500A LiFePO4 Motorcycle Battery, 12V 5AH 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 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

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.

This battery is very light. Looks good and definitely turns my king quad 750 over very easily.
