I picked up this battery from Amazon in April 2016 for my 02 electra glide classic, and it’s been a fantastic performer for years. I’ve kept it maintained with a trickle charger, and it’s powered my bike reliably through ride after ride. It’s starting to show some age now—getting a bit weak and struggling to start after sitting for 5 days without a charge—but that’s to be expected after nearly a decade of use. For the price and the solid run it’s given me, I’m still giving it 5 stars. Great value and durability for any Harley owner looking for a dependable battery!I just ordered it again.

I have a 2017 street glide special and a 2021 road glide special bought 2 batteries on Jan 7th had them on trickle chargers took them off chargers both died within a week ..... one charger says that its bad. now I need to more new batteries. Batteries I had lasted # and 4 years then I go to return them and they have a one month return obviously I’m by the month. I bought them on January 11 didn’t put them in right away once I did. I’m finding out their junk complete junk. One of them won’t take a charge at all and the other one takes the charge but overnight it’s dead and that’s after taking them out of the bikes again.

This is my third XRated battery. First time I purchased this brand and type I got a solid 3+ years of good service. The last one I purchased in 2017, I got a whopping 7 years out of it before battery woes hit me. So naturally once this model (HDX30L) became available, I got a third one. Hoping for another decent service life out if this one.Be careful with sellers. Some will specify their brand and model fit or are “compatible” with your bike model when in truth they are not. Battery post set back is the key. Look at the images carefully.This XRated HDX30L is a direct drop in bolt up configuration, and includes the two 1/8” stand-off brass spacers that allow simple and secure fastening. Came on time and fully charged

My original Harley battery died with no warning. I went to a popular HD fourm(s) (get it?) and asked what battery to buy. The overwhelming choice was the Deca xx, which can be purchased under many names, including X-Rated! The price was great (same as everywhere else) with free shipping. The surprise was how quickly it arrived. It was promised Monday, it arrived Friday, just in time for the weekend. Five stars, five thumbs up, perfect. Oh, it came fully charged. Dropped right in, fit perfectly (2010 HD FLHTC), and started right up. Now, if they would drop by and pickup the old battery....Jan 2022 - just died, lasted 5-1/2 years and probably damaged it by leaving it sit for 6 months in storage. Not bad!

My 2013 Road King would sometimes hesitate in the initial turnover of the engine. It always started but my initial " Oh No" when I hit the starter was getting old, and a bit more frequent. I checked my 3.5 year old OEM battery and found it at 12.35V. To be safe, a new battery was in order. I really like Odysee Batteries, but reading information about maintenance charging using just their special chargers turned me off since I have several Battery Tenders. The X-Rated battery seemed be be the most popular for OEM replacement, and good reviews, so I went for it. Delivered in 2 days, checked state of charge and it was 12.65V. I put on a tender overnight, and had a 12.72V before installing it. Plus, $90 less than the Harley inflated price. Easy install, perfect match to the OEM, and that first start was like music to my ears. No hesitation, just immediate power to turn over those 103 Cubic Inches, and engine is alive immediately. That's the way I expect an engine to start now-a-days.

Great battery. Arrived on time with a full charge, 12.85 volts. Fits perfect and works great in my 04 Ultra Glide. Handles all the loads while starting with all the other electronic stuff turned on. I have had it only a month, so will update on longevity at a later date. I was really disappointed with my last Harley battery. Just one caution, If you are like me and like to over-torque things, use caution, the torque spec for those bolts to the battery terminals is 60-70 inch-lbs. So, don't lean on it. I had to tap new threads and get out my torque wrench. Hope I saved you some time. I was an hour late for my ride. Keep the rubber side down. Thanks, Denny

Hey Folks,Just installed yesterday, April 15, 2015, with an odometer reading of 11.5K, in a 2011 Road King Classic. It had a strong charge out of the box. Worked great on a 40 mile test ride. So far, so good. I will update in coming years to let you know how she's doing. Third party batteries are always guilty until proven innocent. So, we'll see how it goes. TIP: My old Harley battery strap just snapped as I went to remove it. Use bungee cords to make sure you get all the posts and wires and engine control panel pulled back out of the way so nothing grabs on to the battery as you lift it ou. The battery compartment is very tight, especially for us big hand people. I had to replace the strap with a nylon dog leash so I can pull it out easily next time. UPDATE 3.1.2017. Battery has done very well. I don't ride much and when I do, it delivers strong cranking power. Still satisfied with purchase and lower cost.
