A kick in the pants ~
I bought this for my 1995 Suzuki Intruder VS-1400, instead of another $110 12v ten-pound lead-acid 14BS AGM battery. The old battery was rated as 12 amp-hours; this one, just 4AH. But the higher 13.2+ voltage and alleged 5000 recharge cycles, and especially the 2.1 lb weight and lower price, got me.Changing the battery on the Intruder, which was styled in California and built in Japan, is a nightmare. The battery drops out the bottom of a compartment in which it sits, which would be great IF the factory battery cables were long enough to let you access the connections on the top of the battery once it’s out. But noooo, you are literally working with under an inch of clearance for your fingers and wrenching or whatever because hanging by its cables, only the bottom half of the battery appears. Thanks, Suzuki.That said, wrestling with a two-pound battery beats the pants off a ten-pound one. And when finally completed, the bike’s starter cranks like there’s no tomorrow with that extra volt-plus on tap.Five stars.

Awesome battery
The battery arrived on time and it was well packaged. I ordered the battery for my duke 790 and even though the Amazon site says this model doesn't fit my bike the product company says it does. And it did fit the Duke. The lithium battery is 1/2 taller than my current lead acid battery. The bike fired right up and cranked very fast and without hesitation. The battery comes with brass connectors that have dual screw holes allowing you to mount the battery upright or sideways if needed. It also comes with plastic spacers to add more Hight to the battery if you need to make it taller. I'm very happy with the battery and with the weight savings.

Easy replacement for my old sport bike
First off, this battery is stupidly light, Like I'm pretty sure that the old school Maglite flashlights were heavier. The big brass terminals look nice, have multiple connection angles, and include the bolts to attach your bike terminals to them. I ordered the charger recommended for the battery, so the tiny little charger topped up the battery without issue. I unplugged the battery for a couple of weeks to see if it would drain down due to a bad cell. Battery held charge just fine, and the included voltage tester made it easy to check. The only thing that would drop voltage now is if my bike has a parasitic drain. Installation was pretty straightforward, the battery includes a couple of standoffs to make sure it fits snug in your battery box. I used two of the four, and it snuggles right into the battery box, nice and tight. Bike starts up real quick, the LiFe batteries have plenty of punch to spin the 1 liter engine over, and electrically, the bike seems to have no issue with headlight function, or flasher speed. Time has yet to tell on if my 24 year old voltage regulator plays nice with the BMS, but I don't forsee an issue on that front. All in all, a wallet friendly, super light, and easy replacement for my bike. I'm happy so far, especially as parts for old sport bikes are getting hard to come by. Two thumbs up from me. I'd give it three, but I don't have that many hands.

Screwed again
I received the battery on 3/30. I installed it in my bike on 4/3 and the bike fired up perfectly. I rode it all day long the next day with no problems and the bike started every time. I tried to start it on 5/16, it finally quit raining, and the battery was completely dead. I have tried for the last two days to get it to take a charge, with no luck, and yes I do have a lithium charger. Can not find anything about a warranty.

Did not fit as described
Did not fit my 2014 Vstar as it said. It would.

Great for limited space.
Installation was much easier with the adjustable plates. The terminals are also removable, making it possible to connect all of your wires to the terminal, then fasten the terminal to the battery once everything is secure - it beats wishing for a third hand if you're working with limited space. It's still snowing where I am, so it will be a while before I can write a long term assessment, but hearing the engine fire up for the first time in months was wonderful. I will say it seems to fire much quicker than the old SLAB, and all lights are as bright as ever.
