Weize Lithium YTX20L-BS, Group 20, 600A LiFePO4 Motorcycle Battery, 12V 8AH ATV, UTV, Jet Ski, 4 Wheeler, Snowmobile, Personal Watercraft, Seadoo, Polaris, Generator and Riding Lawn Mower Battery

This is the best battery ever. I have installed this battery in two of my generators, a 13KW DuraMax and a GenMax inverter 9KW and in both cases the electric starter starts every time, even if it's been 6mo since I started it, it still starts great. I never have use a battery tender anymore. These just keep a good charge for a very long time. It fits perfectly in the generator mounting space. I think it's actually smaller than the original lead acid battery. I simply use the built in charger from the generators. I haven't had any issues with charging at all. Fantastic battery for the price.

I got this for my 2008 Walker B18 lawn mower. It has a very small space for the battery. I bought a small Lead Acid motorcycle battery last time and it only survived a couple of years. This fit better than that one did, allowing me to actually secure it as designed. It provides more juice to the starter, turning the engine over faster and making starting much easier. I've no idea how long it will last. I'm not convinced the charging ability of the B&D engine is all that great, but after using it a half dozen times, it still seems fine.

I was a little bit nervous about going from the Harley AGM battery to a lithium battery, but so far I am really glad I did! The cranking power is sooo much better! I would say that this Weize battery is an extreme value! I have only done a couple of rides with it, so I can't speak to the longevity of it. But I have done several starts and stops with it, and no problem, so I'm not so nervous now. The voltage is right up there and it turns the bike over very well! The Weize battery is about 1/8 inch shorter than the OEM, but no problems with the hook up, and all the other dimensions were the same so it's not moving around.

I have a 2007 Suzuki m109r, This is an 1800 cc V-Twin engine and it requires quite a battery to turn it over.... The last battery I had in this motorcycle was a shorai lithium battery, and it would literally crank this big engine like a capacitor discharge.... After about 4 years and probably because the bike had been sitting for so long and not being charged regularly finally failed so I installed a brand new mighty Max lead acid agm battery rated at 230 cold cranking amps .... The battery worked fine for initial startup while the engine was cold, but once I ran the bike and got the engine hot I had to hit the button three times to get the engine to rock over to start.... So I ordered this battery which claims 500 cold cranking amps ... It fit perfectly in my Suzuki M109R... And initially it seemed to crank the engine over well, But then back to the labored cranking... When my bike is running it shows about 14.2 volts charge rate and when the bike is sitting after a week or two it shows about 13.4 before starting... When I hit the start button the voltage drops way down and yes my cables are tight and there are no accessories drawing off the battery when the bike is off... It shows the weight of this battery to be over 3 lb but as you can see in one of the pictures it's only about 1.6 lb... Who knows maybe I just got a bad one and if you were cranking anything but a big b-twin I'm sure it would probably do the job... This particular battery that I got is nowhere near 500 CCA I would guess it's closer to about 180

Works great in my atv so far. Starts faster and the winch is quicker. Fit perfectly in the original location and is much lighter. Need to see how the cold affects it and how long it lasts but good replacement so far.

Put this battery in an older Honda Valkyrie. Lots of power, have never had a battery turn this big 6 cylinder motor over this quickly! The fit is snug, but all batteries are snug in this motorcycle. If it lasts as long as it is supposed to I will be $ ahead, compared to replacing the battery every 2 years.

I purchased this Weize Lithium YTX30L-BS battery for my 2003 HD Road King Classic. The last battery's cranking amps were slowing dwindling and required frequent charging over the last few months. Easy enough to tell as it lagged a bit at start time. The old battery originally had about 400cca but this new Weize Lithium touts 700cca. And of course, there is such a HUGE difference when you hit the starter. Now, it cranks the Road King right away with no hesitation. Out of the box the battery registered 13.6 volts. I topped it off with an appropriate lithium charger which settled it in at 13.8 volts before installing. The battery was a perfect fit and the terminal blocks well placed for easy connection of the cables and lugs. This Weize battery weighs in at 6.2 lbs. enabling me to set it into the motorcycle battery compartment with just one hand. Nice quality hardware included in the package for connecting the battery cables. So far I am impressed with its performance. And after having said that, only time will tell as I only received this battery yesterday and installed today. I've read that this unit is designed as a "starting" battery and not really to be used for extended discharging of high current items for long periods of time. Since the Road King has no power sucking lights or motors or other items that would draw high current continuously this battery should work just fine for a looooong time!

Ordered two of these batteries. One for my 2004 Road King and the other for my 2009 Road King. These fit perfectly in both and they are super light compared to AGM batteries. Now to see how long they last in the Arizona heat...AKA The Devil's Cauldron, currently 105 outside and that's fairly cool compared to last week.
