One might think there is not much to say about a motorcycle battery. However, I was really impressed with this product. In all honesty, I had my doubts regarding the lithium technology. I have ridden for close to a half century. The primary bike over the last 20 years has been a 2000cc V-Twin. When I installed this battery it spun the big engine like a top. No cranking, hesitation, etc. Also like the fact it has a little charge indicator light on top that reflected it was not absolutely "topped off". Every start since then has been exactly the same. At this point, I would say it represented a great value. My experience has shown that a lead based motorcycle battery might be good for a couple of years or so if one keeps it on a maintainer, etc. If this EBL lithium makes that mark it will represent a vast improvement over any battery I have used.

Well the battery tested fine on the bench, BMS cut off at about 14V during charge and about 10V on discharge. I put this in an old Sears riding lawn mower and it started just fine. However, after about an hour of use it caught fire and melted. I was lucky the whole mower did not go up in flames and me with it. I suspect that high voltage and maybe even AC noise did something to the BMS and caused it to over charge. Many reviews for this battery are free product reviews, keep that in mind. The seller/manufacturer should warn buyers of problems with older engines that use the battery to regulate voltage. Once the BMS cuts off charging, the voltage is largely unregulated. This may have caused the fault or there may have been a bad cell.After further investigation, my mower has a 1/4 wave rectified AC current with no regulation and most likely that very spikey Voltage signal fooled the BMS allowing the battery to continue charging until thermal melt down. These batteries should not be used on such a poorly regulated system but they should also be designed not to fail in this manner. Many riding lawn mowers have a poorly regulated DC voltage output that is also not pure DC. Many use the battery to help regulate things. If you have an old lawn mower, please do not use one of these.

The 2.5Ah is a great battery for a 250cc.Initially I assumed it wouldn't be able to power the starter in the 250, but it has more power than necessary. If anything I'd say the 2.5Ah is powerful enough for up to a 350 or even a 400cc.The 5Ah is perfect for my CFMoto 450. It's got more power than I need to start the bike. The only reason I went with the 5Ah version instead of the 3.5Ah was fitment. The 3.5Ah was too small for the compartment. Also, the bike uses a t-box with parasitic drain. So the 5Ah works great for 30-60 days of no riding.With the 3.5Ah I would have needed to disconnect the battery during such long time no riding, or plug it in a trickle charger.I also bought the 2.5A for my cg250.Due to an electric error, the starter kept cranking the engine for 2 whole minutes, even with the keys out of the keyhole and the starter button in off position. This was no fault of the battery of course, but I was amazed that the 2.5A battery just kept cranking that thing without seizing, for 2 whole minutes, until I was able to fix the issue.Also, one of my engines had a charge issue. This bike just kept riding for 2 days before the battery gave out. After a 30 minute quick charge, was ready to go again.

Didn't quite fit in the original battery's position, but it came with foam shims and for my 2003 BMW R1150rt it works! Fantastic. Starts to bike every time. Has plenty of cranking power. Great battery for the price.

Installed on my Ninja 400 last year. Still working fine. Super light compared to the OEM battery.

Works in my GPX tse300r or KTM 300xcw. Comes with a base extender as this battery is shorter than the stock. Seems well built and packaged neatly. Time will tell how long it will last, but the price was good

If you are buying this for an actual motorcycle...don't. I'm not sure why Amazone or anyone else would say this fits my bike. It's 1/4 the size of the actual battery. How am I supposed to use it? Will it actually works who knows i can't install it because the cables don't reach it. If I raise it up and connect one, I can't reach the other. Waste of time and money. Real nice battery, don't get me wrong, but completely useless in my motorcycle. (Which Amazon says it fits)

Works light
