Review: Almost 7 1/2 years out of this batter on a Harley! - Bought this battery back in July 2018 for my mother in law’s softail deluxe. Kept it on Battery tender during the winter months. Yesterday 11/28/2025 was the first time it failed to start. Definitely has been a great battery.
Review: Fits and works great in my 2011 Harley Wideglide - UPDATE AGAIN!! I reached out to Throttle X and their customer service is excellent! They replaced my battery in a week and now I’m rolling again with a brand new battery! I am happy with this company! UPDATE!!! Do not buy this battery!! It is now dead and didn’t even make it one year! Starts out great but then just dies and will not even take a charge! Better buy the 2 year replacement plan if you buy it!! I went from 5 stars to 1 star in 11 months! Turns the bike over probably better than any other battery I have bought. Im not sure if it's actually 550 cranking amps but it spins the engine well, and faster than the auto part stores batteries. No regrets here, I'd say it's worth the money.

### ⭐⭐⭐⭐⭐ Perfect fit and very reasonable cost!
*by G***C on December 4, 2025*

So far, so good! I wanted a more powerful battery for my FatBoy, especially during the cold weather, but was concerned that ordering it online would be a problem if it didn't fit or did not have the power it claimed. I was very please that it is exactly what I needed. the same size as my 310 CCA battery, but with more power. The install is a breeze, with the installed connections being threaded with the standard bolt specifications. (Many other batteries I have used come with no threads and require the use of an undercut to secure the cables. This is particularly problematic on motorcycles because the battery drops down into a recessed opening, and with the very short cables, it is almost impossible to get everything lined up just to get the bolt started.) The only issue still a mystery is "How long will it last?" I always keep track of any maintenance or repairs to my vehicles, and I will post a review if I have a problem. Just so you know.
