Yuasa GYZ20HL Factory Activated AGM High Performance Battery

This new generation of maintenance-free batteries delivers higher cranking amps for vehicles that require extra starting power from the largest motorcycle battery manufacturer in the world.

Great battery Cranking power is sick, bro. No problems. Super tight. August 11, 2016
So far so good I had the factory battery in since the purchase of my 09 Street Bob. It wasn't turning over so I ordered this replacement. It took 4 minutes to swap it out (most of the time was trying t remount the battery strap). Started up first pull. I'll let y'all know if something changes, but, so far so good. June 6, 2016
Yuasa Battery Excellent battery, easy to install. Much better than the Harley battery my bike originally had. March 22, 2016
IT'S ALIVE! I bought this battery for a friend. His poor FLST died not too long ago. He was a little upset so I picked this bad boy up for him because it sounded like a bad battery. Went over, swapped this bad boy in and she started up on the second hit. It runs, it's great. Can't complain. March 5, 2016
So far, so Good! Ironically, although I purchased this product at the end of January, I just got it in my bike two days ago. After doing so, at one point I barely hit my starter switch, and do I mean barely, and it turned over immediately. A couple of the features that I really like is the flush terminals with built-in brass nuts; this reduced change out time by at least 30 minutes. I rated it a four because (1) I haven't had it installed that long and we have some cold days coming; I will have to see how it holds up in the cold; (2) the warning label shows through my battery cover; I would rather have a cool design of some kind or at the very least the name of the battery. Finally, besides the battery, Revzilla's service is outstanding, and that battery arrived in two days hot and ready to go! February 23, 2016
Quality Battery The Yuma Battery is a excellent quality battery. It was very simple and quick to replace on my 2013 Harley Breakout. It gave my bike a very quick start without any lag when I first press the start button. It starts my bike the same whether it is hot or cold outside. I would recommend the Yuma Battery to anyone who needs a new battery or just wants to upgrade starting performance on their bike. December 7, 2015
Awesome step up! I got this battery for my 2012 H.D. Blackline. The battery is a beast compared to stock. Cranks the bike up very quickly. I definitely recommend this battery to other H.D. owners at the very least. July 22, 2015
