The battery itself is fine. I have been buying batteries from this company for a long time. The only issue I had was that the terminals were not on the same side as the factory battery on my Husqvarna YTH 22V46. I had to take the battery box out and pull the wires in to the box from a different spot and they just barely made it to the terminals on the new battery. ... show more

    • Works ok but doubt CCA rating
Edition: ML-U1-CCAHR
I installed this in a Generac generator. It was rated at 320 CCA (minimum recommended) but the generator reports low battery when cranking (12.1 volts vs. 13.4 no load), so I suspect that the CCA rating is a little optimistic. Other than that, it has been working ok for a couple of months. The true test will be when temperatures drop below freezing. EDIT - 1/1/24 - The battery continues to work OK. The voltage when cranking drops to 11.9 Volts in cold weather, but the generator starts up fine and does not log an error. ... show more

    • Best battery brand out there today.
Edition: ML-U1-CCAHR
This brand has served me well since i first bought a battery for my generator. Their battery lasted 7 years which is pretty good. Decided to get their brand for my fathers ride-on tractor since walmart everstart's only last 3 yrs. A bit pricey (double the price of everstart) but hopefully that means double the life. Fit was good in his craftsman T2000 ride on. Needed 230CCa, this battery puts out 320CCA. Fully charged on arrival with free overnight shipping! ... show more

    • Great purchase.
Edition: ML-U1-CCAHR
2nd time buying from this company, very pleased. I have a small 4 wheeler battery and it's doing great so I bought a bigger one for the lawn tractor, arrived reading 12.7v (DC) on multimeter. Working flawlessly. I got a sticker with the first one, and was hoping for another but sadly no stickers this time. Great quality battery tho. ... show more

    • No Warranty Info, nowhere does it say AGM on the Battery, but...
Edition: ML-U1-CCAHR
I have bought 2 of these batteries. I wanted the highest CCA (cold cranking Amps) and found this. It turned my engine over where other U1 type batteries needed a jump, to get the riding mower engine to turn... (the motor has a worn compression release). It would crank sometimes and not at other times. With this battery it was great. No Problems all season. So I found my new best friend in this battery and bought another. It worked like a charm also. Then I messed up and left the ignition on on the riding mower, all winter! Drained my new battery dead! I was able to trick my battery charger into charging the battery and it came back to life, but now the "No Crank" problem has reared its ugly head. On the second battery that worked perfect the first season, also drained completely over winter. I do not think it is the batteries fault. I think this other rider has a extremely slow drain that a test light won't even show a draw. I am in the process of slowly charging this second battery, but it doesn't look good. The pros are: the high cranking amps The cons are: no one to contact to even ask a question. No warranty information anywhere. The description says AGM and it says lead acid. If it is AGM say so ON THE BATTERY. If there is no warranty, just say so. If there was somewhere to write, email, text or call would sure instill confidence in us. It is not the batteries fault I messed up. These batteries are great, but their claim "deep discharge recover" might not be 100% accurate. Just to let you know I will keep trying to recharge both of my batteries and if they recover I will let you know & change my review to 5-stars. ... show more
