I think that most of them are now made in China. In a VARADERO I had, it needed a change after 7 years (China).

I installed it in August 2018 on a KLE 500, price (at that time) €88. It lasted until today (DEC 24) with daily trouble-free use with an alarm and the lights constantly on (LED bulbs). However, before this, I had a YUASA (not lithium) on the same bike, and it lasted a bit longer while being €15 cheaper. I probably won't choose it again since it doesn't justify the higher price.

Installed on Honda Xadv 750.. As a first impression, positive.. I will return in a little while to give additional feedback with the cold.. that's why the 4 stars

I bought it in the summer of 2023 and like others I read in the comments, it died in the first cold weather. It didn't even last a year.

First day I put it on and went to start my engine. I don't know if it was a coincidence, but it made everything new on the first ride.. I had damage to the electrical system. Be careful, guys, before you put it on.

Very good battery and at a reasonable price for a lithium one. It is the second one I buy for a second motorcycle. The first one was installed in a Hayabusa and the second one in a gs1100. They have no comparison with conventional ones in terms of durability and starting power.

While it was working, it was excellent, lightweight, and powerful. However, one time I forgot to turn off the lights, and in the morning it was dead. The charger couldn't detect it, so I borrowed a special charger, but since then the battery didn't have much life left. After 2.5 years, I will go back to a conventional one

Very strong battery, until winter comes and the temperature drops below 10 degrees, then the battery dies completely.

Lightweight battery purchased for 89 euros.
I have it in a sym 300 i. Citicom.
It doesn't impress me in the morning when it's cold, like 8 degrees in December. It takes 4 tries to start.
I have changed the starter motor and the electrical system is perfect.
However, the power in cca is not as much as it claims, it falls a bit short.
I also connected it with a bs battery that I had, 8 amps, and now the starter motor is killing it

I have it here for a few days without any issue (it's still early).
The truth is that it is very lightweight and I thought I made a bad choice, but contrary to the initial start, I understood the intensity of the sound and I was satisfied.

Lightweight, good starting performance, and relatively good durability over time (2-3 years depending on how long the engine remains idle and its energy consumption from alarms, etc.).

After almost 2.5 years of daily use (purchased in January 2020) on the SH300 CUSTOM (340cc) with tremendous compression, without ever needing to charge from an external charger, it is a real powerhouse. I highly recommend it, I also got a second one for my big (VFR800X).

250 amps of starting power and not 300 as they claim, measured with two different machines and checked...
But still, its power is very good and it shows immediately

I haven't had it for very long. Only a week. I have installed it on a V-Strom 650. So far, I am satisfied. I will add more comments after about a year passes.
------
After 4 whole years, there wasn't a single day it let me down..
In the winter of 2026, after leaving it on the motorcycle for a month without removing or using it, it did not fail me.
I hope I will come back to inform you when it finally "lets me down"..

After a full charge, it was placed on the machine and became a completely different machine. The battery wore out, and the starter was completely different.

4.5 years and it's still a beast just like at the beginning. Without an alarm (important), it didn't notice 4 months of inactivity and still showed as full. On a CBR600. No malfunctions in the engine and the starter turns so quickly that you think it will pop out and fly.
I never charged it, it doesn't notice 2 and 3 months of inactivity over and over again, and whenever I checked the indicator, it's full. So far it has paid for itself, and the longer it continues, the more satisfied I am.

Lightweight and with very good performance during startup. I am not sure about the discharge time when idle.

I put it in a Tracer 900 and the difference is noticeable. Immediate start without any problem. The difference in weight is expected (LIPO vs lead). Only time will tell its durability.

I put it on my Kymco downtown 300i and immediately noticed the difference in the starter motor. The only problem I encountered was that it was a tight fit because it is slightly taller and the battery cover did not close properly. I used two of the four screws and secured it with zip ties. I hope it withstands the test of time.
P.S. Huge difference in weight compared to the previous Yuasa.
Update. After a year, its performance is like the first day

The battery is excellent in the few months that I have it, it always seems to have power, whereas the conventional one would drain quickly. Its weight is impressively small compared to lead-acid batteries. The machine charges it normally and the indicator always shows it as fully charged.

After 6 months of use with an alarm, everything is fine. I forgot to turn off the parking lights and it completely discharged. I charge it and it lasts for 1-2 days and then dies again. I'm going to get a replacement because I don't want to constantly connect and disconnect it. This time, I will get a simple one that is not so sensitive!

You are supposed to buy a lithium battery not only for its lighter weight but also for its durability. After 11 months of use, the battery is dead, after the motorcycle's inactivity for only about 10 days. The lithium charger does not charge it, and when I took it out, I saw that it had swollen. The charger and the motorcycle were checked and they do not overcharge the battery, so I assume that there was some manufacturing problem, possibly due to temperature

It does everything it says, except that if it completely discharges, the charger does not recognize it. You have to test it with a tester and when only one light turns on, it charges. After 8 months, with only one charge from zero, it's done. It charges in 1 minute and it's empty.
