WEIZELithium YTX9, 400A LiFePO4 Motorcycle Battery YTX12, 12V 4AH YTX7 ATV, UTV, Tractor, Generator, Scooter, Personal Watercraft, Seadoo, Jet Ski, Snowmobile and 4 Wheeler Battery

I’m giving a 5 star rating because of the customer service. I didn’t totally understand battery ratings and thought the 600 CCA. was great because it was twice the CCA of the standard battery in my CAN am Spyder RTL. What I didn’t realize was that this battery is only 8 amp hour and because of the electrical demands of the Spyder a 21 amp hour battery was needed. (Electric power steering, high amp audio, electric seats and grips, windscreen etc). The alternator was being over taxed. I appealed to this company and they graciously offered me a refund without having to return the battery. I’m sure this battery would be great in a vehicle that doesn’t have the electrical demands of the Spyder RTL it did crank very well.

This battery came charged and started my VTX 1300 easily. Same installation as my old battery without any spacer adapter. Works great. 1/10 the weight of my old battery. It’s the second battery I’ve bought from the company. Would buy again.

Had a battery going bad on My Harley, cranking slow! Removed it and noted it was about 9 years old. Pitched the Battery, installed the new one and when I pressed the Starter button, I was Shocked at how Powerful it was and how quickly the Bike started. I would Highly recommend this Product!

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 sucks won't keep a charge have to constantly jump it. Even after it's been on charger all night.

I bought this battery last year as a cheaper alternative to NOCO (which is a straight-up excellent battery) It fit my bike, it had zero issues staring and running my bike all season (HIGH compression Buell 1203 built to the moon) Then, I left it in the bike all winter, cause I'm lazy like that. I live in Maine, winters are COLD. Several weeks of sub-zero temps, warm ups then freezing again. Went out this morning at 34 degrees and hit the start button.....that battery hit hard and strong and after about 15 seconds the bike fired right up. Try that with your $300 HD lead-acid battery.

I use this on my 2004 Harley-Davidson Road King classicFits perfectly in the battery boxWhen fully charged it is a dynamoStarts the bike up right off the batAwesome battery

Great item and good price!
