So thus was bought for a 2008 Yamaha FJR1300 after trying 2 other AGM batteries from Yuasa. They just wouldn't cold start the bike like they should and would constantly needed a top off charge. Stator putting out 13.90 to 14.1v running. I'm pretty sure the Yuasa Battery was a fake of the real deal but Amazon refunded it for me being they are awesome. I decided on this Lithium alternative. My battery is located in the front fairing by the fairing so a lot of weight on the front end. This battery weighs 1/3 of the old one, has a cord that displays the health and a spot to plug in your maintainer. Use a LITHIUM CHARGER ONLY. I got Optimas D200+ for $90.00 and it's a matched set for the battery. Time will tell if the $300 investment was wise but I don't want to come out to a dead bike. As a bonus this battery has a booster built in the event your battery drains. It will cut off the parasitic drain and keep enough to start your bike to make it home. Price wise....... sort of expensive but it IS cutting edge tech. Size wise.....1 foam space at bottom made it a perfect fit. It feels like the plastic is well molded and feels like a quality product. It came on time, boxed attractively and includes everything you need to install it. I'll update this in 3 months to give anyone interested a more long term review. IT SPINS THE BIKE TWICE AS FAST AT COLD START. UPDATE: It's been 3 months since I bought this and I'll say it still continues to work great. The dongle on the battery allows me to monitor the charging system and load on my stator. I've used the CPR feature twice jysy to test it and it's flawless. I also bought the D200+ charger but unfortunately, it went out on the 2nd charge. It was replaced and so far thus one has been good, time will tell. Happy 😊. UPDre

Love the built in jump start feature.

Super high quality battery! The higher cranking amps makes a huge difference turning over my 1900cc Vtwin. Also purchased the DM400+ charger to go along with the battery. Battery is super light and has 2 extra terminal posts which made it convenient. Battery comes with a 5 year warranty as well! They also include some nice foam blocks to take up space and prevent battery from moving around.

This battery is terrible. The proprietary charger, LED read out, and cable are ridiculous and keep it from fitting in tight places, like motorcycles... 4 weeks in the garage and the battery was flat dead. For a lithium battery, that is horrible. You have to leave the giant LED charger cable accessible because the battery "goes to sleep" when the voltage gets low and you have to use the button on the LED read out head to wake it up. Whoever designed this clearly doesn't use it and, god forbid, they could just use a standard charger cable connection that we all have a dozen of already. I'll go back to Battery Tender lithium since I just wasted a ton of money on this piece of crap. Optima had always been great in my cars and trucks. They missed the mark with this one, big time.

VERY GOOD PRODUCT BUT THE COST NEEDS SOME ATTENTION, TOO HIGH FOR WHAT IT IS. USED FOR ATV

Fantastic battery, was debating on getting a lithium battery but decided to pull the trigger. I got the battery and the charger for it. Both are great products. The battery has never left me stranded!! In a few certain situations where a normal battery would've left me in a bad spot this battery with its jump start feature has saved me. I would highly recommend getting this. It will save you

Foam spacers made for snug fit. Installed easily and ran cord out through back tool compartment(taillight assembly) on 2018 Honda trx500fa7. This would easily fit my 2022 atv as well, even though Amazon says that it won’t fit. Battery working fine. Hope it lasts longer than the stock batteries. A new battery seems to resolve shifting and starting problems.

Great battery for motorcylces. if you can get one over the cheaper batteries, i would suggest it.
