NOCO Lithium NLP20, Group 20, 600A Lithium LiFePO4 Motorcycle Battery, 12V 7Ah ATV, UTV, Jet Ski, 4 Wheeler, Quad, Riding Lawn Mower, Tractor, Scooter, PWC, Seadoo, Polaris and Generator Battery

I have a 1993 Harley Davidson FLHTC. I've replaced the motor with a 113cu high compression engine. I added electric compression releases, but the motor still turns really slow with the AGM battery. The problem is that the battery compartment only allows 3.5" for battery depth. That max's the CCAs to 350. I bought an EarthX battery, and it was amazing. It was also 800$. It quit after a year. EarthX honored the warranty and sent me a new one. That one lasted about 8 months, but I found that a mouse had chewed my ignition wires and it send a dead short to the battery. That certainly is not covered under a warranty. Not having 800$ to shell out again, I bought a Wicked Start AGM. It's supposed to be 500CCA. It certainly didn't spin the motor like 500cca, but it started the bike. Just went to ride this weekend, and it was cold. Battery was fully charged, but it cranked very slow, then died. I jumped it with a jump pack and it worked all day. Tried to start it that night, after the temp dropped, and it died again. Battery tests good, it just can't crank my motor when the oil and the air is cold.Back to lithium. Did a lot of shopping and found this Noco. I like their chargers, so with the reviews, specs and price, I ordered the NLP20. Installed with no problem. It has really nice cable mounting options! It's light and has everything you need to make it taller of shorter with the accessories they give you.Anyway...the motor spins just as amazingly as it did with the EarthX. Starts in cold (it was 48 when I started it again this morning) just as vigorously as when it's warm (it was 80 in Daytona for Biketoberfest last week).I can't speak for longevity, but I'm hopeful. There are good and bad reviews for almost everything. For the price difference between EarthX (or even Anti_Grav) and this NoCo, it seems well worth it for me.Update 2-19-2024:Went out to the garage yesterday and started the bike for the first time since early November. It was 40 degrees, and the bike cranked super-fast, with no issues.

I purchased the NLP20 NOCO battery for my '95 Heritage Softail with a 117 c.i. S&S motor in it because even with the electronic compression releases, it turned over very slowly. The lithium NLP20 turned it over extremely fast and the Bike started right away. I highly recommend this battery to anyone running a High performance motor. I don't worry any longer if the bike is going to start and no longer carry a jump box in the saddlebags. Since I didn't have a charger that I could use on the lithium battery (yes it's different then an AGM) I purchased the NOCO Genius 2 battery charger which will charge AGM, Lead Acid and in my case Lithium and I must say it works very well. Both products were packed EXTREMELY well. Due to battery's small size I had to make a few minor adjustments using the included rubber pads, no big deal and worth it in the end. Don't forget it has a five year warranty. I use to get 2 years at the most with a stock Harley battery. I'll see how this holds up but so far I am very impressed with it and will most likely purchase again in the future.

Had to grind a couple nubs off the battery connectors on the bike side though, but trivial stuff for anyone handy. Even though it was half charged (all lithium batteries are supposed to be shipped that way), it started my 1800cc motor 6-8 times right off the bat, with no charging inbetween.Since it has a much smaller Ah rating than a standard battery, you should NOT be leaving it sitting for much time with the lights on but not running, as it will drain much quicker. But for starting, it does the trick, and very light.Can't speak to longevity though yet.

Like most reviews, at first battery does a fantastic job. Great power, slow discharge, and no issues other than the posts don’t fit the motorcycle battery connectors and have to be modified. I installed my NOCO 20 on my 2018 Honda Gold wing February of 2022 and no issues until the winter of 2023 around November. December. I went to start the bike after a week or two and while it did start there was a hesitation before starting this time. And noticed some of the settings on the bike were lost, as if the battery had been disconnected at some point prior. From that point on the loss in charge started to increase until at one point from a full charge with a lithium charger battery will discharge in 33 days and not be able to start the bike. I ride all year and don’t use a battery charger that often. That said, after install I could go a month with the bike sitting after a ride and be able to start it just as strong as day one. For some reason after a year and a half just started discharging at a high rate and I did use a meter to check to see if I had some kind of parasitic drain and did not.

I have a 2003 Yamaha snowmobile - and every year I need to put a new battery in it because the old battery no longer holds a charge. This was my first attempt at replacing a motorized vehicles battery with a lithium battery. The battery seems very well made - and comes with spacers to help adjust the height of the battery that worked well. It weighs a fraction of the old battery - and its a tight fit where the battery goes - and being able to hold this battery upside down, sideways, on end etc - made it easy to put the battery in place. I was worried about charging the battery with a standard battery charger (Mine is a noco brand charger) - but I plugged it in and about an hour later - had a green light that my new lithium battery was fully charged. So far since I have had this battery installed - the snowmobile jumps to life with a touch of a button - the motor turns over quickly. Seems very powerful thus far. The big test will come next year after the snowmobile sits for a winter. But so far so good!!

Although my battery was defective, their customer service (actual human answered) helped me troubleshoot the problem and sent out another unit. Very impressed with their customer service!
