Ytx4LBS, so far so good
I usually use the mightymax (mm) brand with the clear window for the acid but decided to go with these instead due to shipping time no so much for cost as the mm are about $4 more. I bought 2 cause I have 2 taotao ATVs they arrived fully charged about 13.2v but I still stuck them on my solar bank charger for 2 days mainly cause I wasn't ready to work on the ATVs. Got around to fixing up my 125cc and put this then nothing....atv has not ran in over 3yrs. So no plastic fairing anywhere as it all flaked off and I just replaced the PZ20 carbs and fuel line and filter. I have added external accessories like an extra led spot light on the handle bar. The spot light lite up but no cranking. I thought maybe the switch was bad and was getting po. Then it dawns on my, how about the keys to the ignition 🙄. Jeez what reeree! Got the key, turned the ignition on, press the rear brake, and push the start bullion and it started cranking. Was cracking for about 2min as the fuel hadn't reached the new carbs and finally the engine started catching. I thought the battery was gonna give out but nope it stayed powered up until the atv fired up. These small batteries/motorcycle batteries really are a hit or miss as far as longevity goes. The acid leaks out if you keep on trickle charger. It's cheap and it works. Has my thumbs up. Would recommend and buy again.

Battery for scooter
I got a great deal on these batteries. My only problem was that I bought the wrong voltage with the proper cranking amps needed. My mistake. Arrived quicky so no problem was with the actual purchase at all
